Damn, this is the man that inspired me to be a mechanical engineer, 7 years later I achieved that goal, and obtained the job I always wanted, thank you man! Keep up the amazing job.
Because... life should be boring, we should only eat paste and grass, and only listen to elevator music? Edit: I'm totally kidding just to be precise. I do care if you have easily indused nausea
IF Optima felt confident in their claim of "Can last 3x longer than regular batteries" then why are their battery warranties no different than the cheaper flooded acid batteries? For the price on one optima, you can buy nearly 3 ordinary flooded batteries. I'll take my $80 flooded and you can have the $240 Optimas from Mexico.
@@nthgth i am not talking about beating it with a hammer i'm talking about all the people who would run with a bad alternator over charging under charging killing it constantly. we are talking electricity and charge cycles there is lots of ways you can kill a cell or weaken them by "abuse" that won't leave any tell tale signs that would just look like a manf. defect and they have to protect themselves. these batteries are not meant for a everyday driver in a normal car they are meant for higher "abuse" scenarios
I get that he has to pay the bills, and he's got a pretty rad way of doing it, but it just smells a little off when he's wearing the company's shirt while explaining the virtues of what happen to be the type of battery they're known to produce.
Dominic White It's not "shameful", he helped A LOT of people (including me) to understand automotive subjects and the engineering behind it, teaching isn't shameful. Also as far as I know he loves cars in the first place.
You're a smart guy and I like your videos. It's difficult to provide a service to both your viewers and sponsors. The camera tricks on this video feel gimmicky. Please don't move further in this direction.
If this is supposed to be an Explanation then there's no need for the distracting background music, camera angel shouldn't jump through all those weird-angle intercuts and main focus should be either on the person talking or on the whiteboard. As a short lecture on Car Batteries it is too distracting and as a sales promotion it is too boring. Jason, you've mastered it and I seriously think you should teach these guys how to make a proper EE video.
Haha, thanks for sharing your thoughts, I’ll certainly keep it in mind for future sponsored opportunities! I agree that when diving into chemistry it can be a bit hard to follow with short clips. I’ll take everyones thoughts into consideration! For what it’s worth, I thought the editing was great, but perhaps a bit too fast paced for the topics discussed.
no one watches tv. cept. old people. and most old people are dead so we dont cater to them. try bringing back anti pedophilia instead. thats an old people thing that was cool.. oh and not watching tv. thats why old people built a nation but the kids today cant even read and count and rob every other nation that builds
Engineering Explained: I'm ambivalent about this. I mean, I want to like it, it's certainly different, but I also find it too distracting. I wouldn't give up on this idea entirely, but tone it down a bit. Or actually, a lot. :D
Considering this guy's videos and how he looks at everything from an engineering standpoint rather than brand or hype, when he puts on a company t-shirt makes a video for their product even if he's getting paid it has more credibility than someone else. This is not the type of guy that would accept millions of dollars from a company to push a product he personally did not believe in.
The jump cuts and low dolly shots of the side of a table are really antithetical to your style. I think whoever directed this bit doesn't understand your drawings or why we'd want to see them for more than .3 of a second. I feel like the editing pushed this from a "sponsored-yet-still-full-of-information" video over to the advertisement side of things.
Yea whoever directed this was a f**k-stick.”ohhh I’m gonna show you a table with stuff written on it, but it must be too much for the average viewer to even attempt to understand, so I’m gonna make it look like something big is happening and cut out all the “boring” stuff. Worthless.
I discovered that my Chevrolet spark EV uses a 12v AGM battery. Searching the internet for more information, I found a lot of confused, contradictive, speculative, unreliable information. Will the traction batteries charge the 12v battery when the car is parked and not plugged into a charger? Can you substitute an AGM with a flooded battery without harming the electronics? Can you put a battery charger on the 12v battery in an EV just as you would in an ICE car?
Engineering Explained is definitely one of the overall best channels out there. The video quality is excellent and the content is explained clearly. Please don't ever stop making videos! You're making a huge favor to people all around the world who are interested in engineering and technical stuff like this. Education is always good for you.
Firstly, I love your channel and videos. Not only I learned a lot but also enjoyable. I have a little note about this video, the cinematography was extremely distracting to the point where I could not follow what was being said. Cinematography treckery should aid the content and not distract from it. I get that sponsors sometimes impose things on you, but I hope you wouldn't let them change the things you do best.. A simple camera set up is definitely the best strategy for educational videos, and let them go nuts when it's time for their product plug.. Finally, have I mentioned that I LOVE your channel? :)
Multiple cameras are fine, but this had way too many cuts back and forth. Very distracting. Great info though. Seems Optima is trying the same route that Odyssey is doing with the AGM non-spiral design.
The cinematography thing was so harsh it made me pause the video after 30s just to comment on it. First you make a nice graphic, but then the camera points at your face while you explain something on that graphic, and panning over your hands while youre pointing at something is even worse.
Anthony Ramsey hyperbole, my man. Learn it, love it. And I agree with him. Shits distracting and makes me feel like he's just trying to sell me a battery while having no idea if it's a good product or not
First off, thank you, I love watching and learning from your video. This video felt a little different than most of your other videos, because it didn't really feel like you gave us a summation at the end with you thoughts and opinions. I think I understand why you did this video the way you did, i.e. Optima kind of sponsored you to to this video, so you can't really say anything negative about their product; that is, if you even had anything negative to say. Anyway, it would have been nice to learn a little more about when you'd want to use the red top vs the yellow top batteries, i.e. truck with a wrench, high powered car stereos, etc. Also, what are the real difference between the yellow top and the blue top batteries? Thanks again for all the videos you post!
Hey there! Thanks for the feedback. Red-top is more purely for high cranking amps, but good overall. Yellow-top has lower cranking amps, but can be cycled a lot more (great for applications like a truck, winch, RV, etc). Blue top is specifically packaged for marine applications (extra terminals), yellow top is packaged for car applications. Chemically, they are identical (but differ slightly here vs Red Top).
Johnson controls is the oe supplier for mopar/fca products. I work at a Canadian dealership and we see a lot of frozen lead batteries. The glass batteries can loose their charge over long periods in the cold, but rarely "freeze" solid and often can be thawed and charged without much fear that one of the cells ruptured when the battery lost its charge in the cold. If your in cold Canadian weather glass batteries are definitely the way to go! They can be saved wayyyy more often then any battery I've seen
crkt308 that might be one of the reasons why I’ve never really had a problem with optimal batteries. I’ve used them in the USA Rocky Mountains and I like them so much I’m not planning on going back to flooded lead acid batteries again but I would like to try a lithium one
Fire the director. Moving shots do not belong in an educational video. This isn't a promo selling a whizbang or a cooking show. Excessive cuts are distracting to the ability to absorb this information. I usually love your videos and the content here is great, but the video direction is not appropriate and the editing not conducive to learning.
Actually, it IS a promo, selling a battery. They aren't even good batteries, they're well marketed batteries. 2 year lifespan on those spiral cells. I know because I sell people XS Power batteries to replace their 2 year old Optima batteries.
Ballistic makes a 4-cell 12v Lithium Iron Phosphate motorcycle battery (EVO2) that weighs less than a pound. I used it in a converted motocross-bike-turned-supermoto and literally strapped the battery inside the airbox it was so tiny! It worked great in that application and cranked a modified 450 4-stroke with ease, although the 8-cell would be a better choice for most street bikes and those are still under 2 pounds.
As of today, our three cars have all had new batteries in the prior 12 months. It's always a pain when an otherwise reliable car needs a new battery, to say nothing of incidentals (some batteries are tougher to remove than others). I'll probably start using AGMs on cars we expect to have around for a while, instead. Great vid! I've been wondering about the hype, but now it's much more concrete to me.
I ran across your channel a week ago, been looking up things for my 13 STI I just got. I think I’ve watched them all. Thanks for the explanations on everything. You make it really easy to understand!

Good info but this video felt kind of scripted and over produced compared to other videos of yours I have seen. Kudos to Optima for sponsoring this, but personally, I prefer your home made videos.
Dislikes?.. Obviously we are in the day and age where excellent information backed by science and research is frowned upon. Excellent information as usual thank you for posting.
I'm learning so much from these videos, and your simplicity of explanation. This helps me with my engineering designs for various automotive components and actual vehicles themselves. Loving this.
The old EverStart Maxx-78S lead acid battery in my truck got me 13 years of dependable use without any maintenance. Amazingly, it could start the truck after sitting months at a time (that was a pretty common occurrence too).
Been waiting for this video ever since I saw the pictures from it months ago. Always wanted to know the differences between those two types of batteries. Awesome job!
Optima were good batteries at one time now they are making them poorly as many have also stated here and on countless car forums .. I went with an Odssey battery and so far so good.
@@space_114v2 Odyssey is the way to go. Their parent company, EnerSys, acquired Northstar in 2019 so they’re really the best batteries money can buy. I’ve always suggested those two and now they’re made by the same company so even better! Plus they have a 4 year full warranty on all their batteries haha
optima used to be made in the USA and had stricter quality control standards... they built a new factory south of the border and let their quality control go... they are not the batteries they once were, and I too won't waste the money on them... the company was sold and the new company is making money off of the previous companies good name while running it into the ground. They won't be in business long at this rate.
Optima batteries are fantastic, I've got 1 in each of my historic cars. One is getting close to 9yrs old and still cranking strong, the other is in a 4x4 pickup that might see use once a month or two without problems for the last 5yrs. ..both yellow tops. Great description, keep up the great vids. ...and the white board
Johnson Controls is the manufacturer of most automotive batteries in North America, currently making Optima, most "store brand" batteries, some of Interstate's batteries, and a lot of OEM equipment, too. You really have to go out of your way to not buy one of their products.
Cars Simplified I think their AGM's are okay. The flooded Johnson batteries can't handle the desert heat. The battery posts eventually cake up in like 2 years. Never seen an AGM do that from them.
We've used Optima batteries for years!! The only way an old style lead acid battery comes on the place, is if we get new equipment... currently, we have about 40 Optima batteries in use... In the last year, we've started using the heavier Yellow top starting/deep cycle batteries... They hold up better in the service truck and in the semis. Good video!! Well explained! One advantage I didn't hear you say is.. corrosion is pretty much non existent with the Optimas... We always make sure everything is clean, cover the terminals with dielectric grease... Zero issues!!! We used to clean everything, then paint the terminals after connecting them... It seals the connection and works also.
This is markedly harder to follow than videos past. Background music is distracting. The white board made differences easier to follow throughout. Sponsorship fail.
Good info thank you! Here in AZ the water filled batteries do not last at all in our summers and I end up topping them off every couple months in the summer. I put an AGM (not Optima brand) in my truck a few years ago and have been very happy
Remember, AGM and Flooded need different alternator voltages. Swapping these will over or undercharge the incompatible battery. So change the voltage regulator to maintain compatibility.
A huge Thank You to Optima's videography!! Best quality (visually speaking) you've ever produced. ...also I'd wear that shirt every day, I've been a long time proponent of Optima's technology. I have a RedTop from 6/08 that's been in 3 different cars through 2 summers in FL, 3 winters in WI, 4 years in TX + more. Stoked you now have this connection in your journey!! ....cheers mate (p.s. ..I seriously need one of those shirts)
Absolutely LOVE this. Such an informative video. I like how you drew everything out.. that way, can see it better in my head rather than just being told. I’ll always love my optima battery and will def keep pushing to sell them at my job. They’re much better quality!
Good technical information. My first and last Optima died after almost a year, was replaced under warranty and that one also died in about a year. I bought an Advance Auto AGM and it is almost three years old.
That’s a good question. I’m not sure on the actual weights, I would imagine for the same weight, the pure lead will offer better deep cycle and cold cranking characteristics. I have a couple sitting in my garage, I shall weigh them!
Dear Engineering Explained, I have noticed the quality of the video has been dramatically improved. I like the "less static" flow of the video and more editing/animation put into it. Cheers and keep it up!
Is this still engineering explained or just an Optima commercial? I like your channel and I understand if you mention sponsors that provided equipment, testing facilities etc., but I do not want to see a six minute commercial about something that you could have explained better without Optima. What about LiFePo batteries or other AGM designs? Why not mention their advantages?
He kind of sold out. Optima used to be a great batteries before they were sold in 2009 and closed their plant in the USA. Now, they are made in Mexico with inferior parts.
I work in a battery production plant, this video is little bit older by the time i am making this comment. Johnson Controls sold off the battery division, it is now called Clarios. Optima batteries quality has diminished a bit since they moved production to mexico. Overall this was a good explanation of internals of the different types. Keep making videos, you doing great job.
Thumbs up for Optima batteries! I've always used the yellow top for my car stereo needs. They will help with the lights dimming on hard bass notes. My old 2000 watt amplifier liked to kill batteries about every 3 months but this one lasted til I sold the car. It was over 8 years of abuse.
TIP: when you are not looking at the camera, we shouldn't be looking at you. So when you are explaining something on the board, going back and forth adds negative value.
TIP: understand what you're seeing before you say anything about it. If you've seen ANY of his other videos for more than three seconds, you'd immediately recognize that the only part of this he had to do with was being there to speak. The irritating editing, lighting, and background music are very much likely out of his control.
Wow that new flat plate agm battery looks great! Very aesthetically appealing. Goes very well with the overall square design of most muscle cars. Now all they need to do is offer different colors for all the battery types and they would be unbeatable.
Let's say I purchased a yellow top Optima battery. If the car won't turn over and the battery seems dead, and I need to get somewhere immediately due to an emergency or other reasons, can I use a traditional battery charger that most of us have in our garage (on max output setting voltage or amps) to charge this battery like a traditional flooded-lead battery? What about short and long term risk from this event?
We did a test with our Police fleet and found the Optima batteries life expectancy was 1 1/2 to 2 times that of flooded lead acid batteries but the price was 3 times higher. The Optima's performed about the same but they did have a lower cold cranking amperage ( 750 CCA vs. 850 ) and lower reserve capacity (120 vs. 150 ) then the flooded lead acid batteries.
Please name the flooded one¨s brand, as I would like to find out a cheaper option for normal, cheap cars. My experience with Optimas here in Finland that they last 4-10+ times the flooded ones do. Actually, all AGM batteries last so much longer than flooded ones, if you find one that physically fits your car or truck there is no reason to buy a flooded one. With your fleet, what may have been the reason for so little margin, usually Optimas are hard to fit to the place of the original; I had to modify the battery tray/box of my H3 to fit a suitable size (electrically) Optima. Usually only electrically "smaller" optimas fit original battery trays, so it is apples to oranges unless the situation is made fair.
I have a small mat-type battery for my garden tractor, and it has out performed the other two regular batteries I had before. It's still working fine after several years of Wisconsin's freeze/thaw cycles.
A FLA battery is 2.1V per cell not 2.2V with resting/fully charged voltage of 12.6V not 13.2. AGMs are usually around 12.8V. You also could have discussed acceptance rate during charging in that AGM batteries can be charged more quickly as they can accept more current.
i put a red top optima in my 07 Xterra once the old factory battery was getting funky.. and it starts up quicker and is great. Plus they're not that expensive compared to other regular batteries. I'm glad i switched it up to the optima. Great video as always.
Great explanation, as always. The editing is really bad, though. EE's usual videos emphasize the actual explanation of the topic, and this feels extremely like the sales pitch it is. Maybe they should've just let him do his usual routine with sponsored content.
I saw some negative comments below from people that feel this gentleman took the easy way out from doing true engineering to do TH-cam videos. Well let me say this about that. He is sharing his knowledge and obviously likes to teach. As a fellow engineer with 30 plus years of experience, I personally feel that it is wonderful that this man is "GIVING BACK" and sharing his knowledge versus some people that are self-absorbed and never make any contribution in life what-so-ever. If he makes more money doing this then in traditional methods, kudos to him. Today you need to strike hard and strike fast to secure you place in society and TH-cam has afforded him with the platform to do so. Regarding the keyboard warriors out there that love to comment from the safety of mom's basement, stop typing and get out there and do something with your lives rather than playing the role of the critic. I can tell that with 35+ years of hard work in the real world, it can be very rewarding!
Optima has been running the agm battery game for. Over 2 decades from what I remember and I been using optima since I’d say my first car in 2008 never looked back 2
Enjoyed the content but didn’t like the constant cuts to you then back to the diagram. Much harder to follow than your usual you at the whiteboard format. It doesn’t add to the delivery rather it distracts. Love your work
Engineering Explained your diagrams are great and I scan them absorbing whilst listening. When the cuts jumped to you I found myself stopping listening because my head was preserving a sort of mental bookmark of the image. Then trying to catch up. Anyways, keep up the good work
I quite dislike the editing in this video..... we dont need to have strafing shots and scene changes every 3 seconds while he is describing something and demonstrating it on paper..... honestly its not only silly looking, but it actually distracts from what he is doing cause you keep shifting the focus away from the topic. Criticism aside though, good video content, I have always wondered what the difference was.
I should also note, It was spicifically distracting when you are doing the in deth explanations/demonstrations on paper. there were many situations where it did actually work, like when you were shoing the actual products exc. Experimentation is good :P
I really don't care about the change of angle as I was not paying attention to these angle changes. My ears are focused on hearing the content but my eyes drift multiple times to that distraction of a candy red car up in the lift. Having the Porsche is a "convenient inconvenience".
Excellent video, very informative. However, unlike the rest of the EE videos, I had to keep rewinding and pausing to read the captions. They were there and gone in a flash, and it was difficult to concentrate on what was being said and reading the added info at the same time. I'm glad this isn't a common format for EE!
~5 years ago got the round 55 Ah Yellow Top and alongside with it 4A Defa battery charger. The Yellow Top is more expensive than regular batteries, but it's absolutely worth it! Month ago it was -30°C here and I didn't have preheating on. Took 3 short cranks and the car started - couldn't do that before with regular FLA.
I bought my MGB 9 years ago with a 6 year old Optima Red. It still charges well and with 15 years on it has 12.5 at startup. I am amazed it is still working like new with 15 years on it.
What I don't appreciate about this video Jason is that you did not state any disadvantages of the "alternative" designs of batteries vs the conventional flooded lead acid ones. There must be some. And this made it too obvious that its just a "Pay to show our product" sort of video with little objective value.
The main purpose was to demonstrate the chemical differences. Like anything, you get what you pay for; AGM style batteries are significantly more expensive (the disadvantage).
I get that, but the message in this video is basically - The battery that is probably in your car is not as good as this Optima one, buy it. Im sure there are more disadvantages in that design other than just price. In today's level of technology it's always about tradeoffs. And even if it was just the price, mentioning it in the video would be appreciated. Keep up the great work. These are just my two cents in form of (hopefully) constructive criticism.
Unfortunately, this video did come across more like a paid advertisement than one of his normal educational videos. The optima golf shirt he was wearing contributed to that impression as well.
Hey EE, I watch a lot of your videos and love the way you explain technical issues in a way that's clear and understandable to the average person. Two comments on this video: 1. you got a few things wrong here. Minor details but this is my speciality professionally so I noticed. 2. It was probably a mistake "partnering with Optima" for this video - but that's my opinion.
The alloy used typically in a flooded lead acid battery is antimony(1-4%). Replacing antimony with calcium gives you a maintenance free battery. Advantages of calcium include improved resistance to corrosion, no excessive gassing, less water usage and lower self discharge. The case can be sealed so the small amount of gassing can condense and return to the cell.
Because it's more expensive, doesn't like being stored fully charged, internal resistance can go up quite rapidly over time and it requires way more "management" than a lead-acid battery increasing not only costs of the battery, but also battery management electronics.
Lipo batteries have many issues. For example, they can't tolerate sitting fully charged for extended periods of time. Lithium batteries also need intelligent management systems, which would add cost, complexity and points of failure. They don't tolerate heat either, which is a big problem for an automotive battery. Another major problem is their environmental impact. Lead acid batteries are nearly 100% recyclable, and you get paid for them. Lithium batteries, however, are much more difficult to recycle, and they are expensive to dispose of properly. Recycling a lithium battery costs more than you'd make off the materials, so a lot of batteries would probably end up in landfills. Another major issue is safety. If a lead acid battery gets overcharged, it damages it and may leak acid. However, if a lithium battery gets overcharged, especially a large enough one to be used in a car, you have a fiery bomb. Same goes for the battery getting crushed in an accident. All in all, 25-30 pounds of weight savings is not enough to replace lead acid batteries with lithium batteries in automotive applications.
Excellent as always. As a personnal experience with Optima Battery, mine was a Yellow Top and was 12 years old in my car (I say was, but you'll see why). Got a bit of audio that needed a better battery. Sold the car (hence the was) with the battery still in it (a,d the audio). Did a test of the battery before selling it : 100% charge ok, and still giving 100% of the voltage ! Never had to recharge it ! Really good quality, and I will go again with Optima on my next car.
I keep buying Optima Yellow Top batteries but I have never had one last more than 3 years. My last one only lasted 8 months. However, I am not giving up yet. They power my stereo system very well.
Wooow very bad video Did not like this technique in any way The good thing about ur videos have always been ur easy to understand well thought out graphs and pics but the way optima took them for u was really bad PS not saying in anyway that being sponsored by optima s bad it's cool af Way to go Jason
The music was unnecessary and I would prefer it slower at your natural, uninterrupted speed. It was a good video though and I am happy for the company to sponsor the video.

Thanks, glad you enjoyed it! :)
Thank you for not doing these crazy dramatic angles and camera pans in your normal videos.

For the price on one optima, you can buy nearly 3 ordinary flooded batteries. I'll take my $80 flooded and you can have the $240 Optimas from Mexico.
because you can abuse anything especially batteries
Warranty is for problems that are not due to abuse.
@@nthgth i am not talking about beating it with a hammer i'm talking about all the people who would run with a bad alternator over charging under charging killing it constantly. we are talking electricity and charge cycles there is lots of ways you can kill a cell or weaken them by "abuse" that won't leave any tell tale signs that would just look like a manf. defect and they have to protect themselves. these batteries are not meant for a everyday driver in a normal car they are meant for higher "abuse" scenarios
@@ericvickery6357 ohh I see, I misunderstood. That is a good point.
Went through 3 optima red tops in one year...bought from Amazon..
I love your channel but not crazy about the "high energy, shilling" camera movements and angles. Just keep it old school, my man.
I think that is his sponsor wanting to film him XD
I'ts a shame. I'd rather see him AND the whiteboard all the time
I get that he has to pay the bills, and he's got a pretty rad way of doing it, but it just smells a little off when he's wearing the company's shirt while explaining the virtues of what happen to be the type of battery they're known to produce.
Amen
Agreed, the camera work is inappropriate.
Dominic White
It's not "shameful", he helped A LOT of people (including me) to understand automotive subjects and the engineering behind it, teaching isn't shameful. Also as far as I know he loves cars in the first place.
You're a smart guy and I like your videos. It's difficult to provide a service to both your viewers and sponsors. The camera tricks on this video feel gimmicky. Please don't move further in this direction.
This channel shouldn’t be looking for sponsorship in Motorsport-related companies, but Sharpie. He’d be a millionaire.
I think you mean Expo. Sharpies are (usually) permanent markers. He uses Dry erase boards.
@@TheMototerrestrial I think Sharpie makes dry erase markers, but don't quote me on that.
They do, they just aren't known for it
I don’t like the way you filmed this. I like when you do it standing up next to the whiteboard, that’s the Jason I know.
Camera moving around every second. Meh.
its because its a sponsored video.
yeah with the bushy nerdy wig
It's an advert.
spider.
If this is supposed to be an Explanation then there's no need for the distracting background music, camera angel shouldn't jump through all those weird-angle intercuts and main focus should be either on the person talking or on the whiteboard.

Jason, you've mastered it and I seriously think you should teach these guys how to make a proper EE video.
Haha, thanks for sharing your thoughts, I’ll certainly keep it in mind for future sponsored opportunities! I agree that when diving into chemistry it can be a bit hard to follow with short clips. I’ll take everyones thoughts into consideration! For what it’s worth, I thought the editing was great, but perhaps a bit too fast paced for the topics discussed.
ready for your discovery channel tv show!
no one watches tv. cept. old people. and most old people are dead so we dont cater to them. try bringing back anti pedophilia instead. thats an old people thing that was cool.. oh and not watching tv. thats why old people built a nation but the kids today cant even read and count and rob every other nation that builds
This feels too formal for your channel, the camera's also very jumpy with awkward angles.
Doesn't help with concentration at all.
Thanks for the feedback!
Engineering Explained Thanks for the videos.
We want this channel to improve as much as you do.
I second that, felt like I was watching a game of tennis.
Engineering Explained: I'm ambivalent about this. I mean, I want to like it, it's certainly different, but I also find it too distracting. I wouldn't give up on this idea entirely, but tone it down a bit. Or actually, a lot. :D
It felt like he was trying to handwave thru the technical details because he didn't really know, and needed to pretend.
Nothing says "impartial examination of the facts" like wearing a shirt that has the name of one side of the problem printed on it
i know right....
Considering this guy's videos and how he looks at everything from an engineering standpoint rather than brand or hype, when he puts on a company t-shirt makes a video for their product even if he's getting paid it has more credibility than someone else. This is not the type of guy that would accept millions of dollars from a company to push a product he personally did not believe in.
Well can you point out anything he said that was wrong and support it when evidence?
The jump cuts and low dolly shots of the side of a table are really antithetical to your style. I think whoever directed this bit doesn't understand your drawings or why we'd want to see them for more than .3 of a second. I feel like the editing pushed this from a "sponsored-yet-still-full-of-information" video over to the advertisement side of things.
David Edmeades, I agree. It just felt like an infomercial.
Yeah, you could also immediately pinpoint where the sponsor told him to say things very specifically. Like, the entire video. It was very un-Jasonlike
David Edmeades The literal definition of sell-out. When it interferes with and changes the content communication.
Yea whoever directed this was a f**k-stick.”ohhh I’m gonna show you a table with stuff written on it, but it must be too much for the average viewer to even attempt to understand, so I’m gonna make it look like something big is happening and cut out all the “boring” stuff. Worthless.
I discovered that my Chevrolet spark EV uses a 12v AGM battery. Searching the internet for more information, I found a lot of confused, contradictive, speculative, unreliable information. Will the traction batteries charge the 12v battery when the car is parked and not plugged into a charger? Can you substitute an AGM with a flooded battery without harming the electronics? Can you put a battery charger on the 12v battery in an EV just as you would in an ICE car?
Engineering Explained is definitely one of the overall best channels out there. The video quality is excellent and the content is explained clearly. Please don't ever stop making videos! You're making a huge favor to people all around the world who are interested in engineering and technical stuff like this. Education is always good for you.
Happy to hear it, thank you so much! 🙏
i agree one of the best !
I gotta concur.
Firstly, I love your channel and videos. Not only I learned a lot but also enjoyable. I have a little note about this video, the cinematography was extremely distracting to the point where I could not follow what was being said. Cinematography treckery should aid the content and not distract from it. I get that sponsors sometimes impose things on you, but I hope you wouldn't let them change the things you do best.. A simple camera set up is definitely the best strategy for educational videos, and let them go nuts when it's time for their product plug.. Finally, have I mentioned that I LOVE your channel? :)
Thanks for the feedback! I certainly take it into consideration and will make changes in the future!
Multiple cameras are fine, but this had way too many cuts back and forth. Very distracting. Great info though. Seems Optima is trying the same route that Odyssey is doing with the AGM non-spiral design.
its like the toothpaste comercials on tv where they keep zooming on angles at the persons face and other
To add to this the cinematic effects also make it seem less personal which is part of the appeal of your channel.
The cinematography thing was so harsh it made me pause the video after 30s just to comment on it.
First you make a nice graphic, but then the camera points at your face while you explain something on that graphic, and panning over your hands while youre pointing at something is even worse.
Nearly impossible to follow with all those jump cuts
Truls Bekk was thinking the same thing
Anthony Ramsey hyperbole, my man. Learn it, love it. And I agree with him. Shits distracting and makes me feel like he's just trying to sell me a battery while having no idea if it's a good product or not
Just use your ear and listen, I hardly watched and was able to follow
Makes me think Johnson Controls required that poor style of video production.
I want one of your drawn charts to hang in the garage forever. Masterpiece as always!
Creeper alert!!!!
Mark he should start a book with all his drawings. That’s be neat
First off, thank you, I love watching and learning from your video. This video felt a little different than most of your other videos, because it didn't really feel like you gave us a summation at the end with you thoughts and opinions. I think I understand why you did this video the way you did, i.e. Optima kind of sponsored you to to this video, so you can't really say anything negative about their product; that is, if you even had anything negative to say. Anyway, it would have been nice to learn a little more about when you'd want to use the red top vs the yellow top batteries, i.e. truck with a wrench, high powered car stereos, etc. Also, what are the real difference between the yellow top and the blue top batteries? Thanks again for all the videos you post!
Hey there! Thanks for the feedback. Red-top is more purely for high cranking amps, but good overall. Yellow-top has lower cranking amps, but can be cycled a lot more (great for applications like a truck, winch, RV, etc). Blue top is specifically packaged for marine applications (extra terminals), yellow top is packaged for car applications. Chemically, they are identical (but differ slightly here vs Red Top).
Difference between yellowtop and bluetop are the terminals. Bluetop has stainless (not 100% sure if steel) terminals, yellowtop has normal terminals.
I agree this felt more infomercial-ish. Hopefully EE got a good payout for it to fund the other (IMHO nerdier and thus better) vids.
.
It felt off because it's a 7-minute commercial.
Johnson controls is the oe supplier for mopar/fca products. I work at a Canadian dealership and we see a lot of frozen lead batteries. The glass batteries can loose their charge over long periods in the cold, but rarely "freeze" solid and often can be thawed and charged without much fear that one of the cells ruptured when the battery lost its charge in the cold. If your in cold Canadian weather glass batteries are definitely the way to go! They can be saved wayyyy more often then any battery I've seen
Thanks for sharing your personal insight and experience with the subject!
crkt308 that might be one of the reasons why I’ve never really had a problem with optimal batteries. I’ve used them in the USA Rocky Mountains and I like them so much I’m not planning on going back to flooded lead acid batteries again but I would like to try a lithium one
The BGM music is distracting...
It's mostly midrange and should be mostly not midrange, so as not to overlay his voice so much. It's busy and constantly jarring.
music is completely unnecessary. @engineering explained, You have magnetic voice, use it!
@TR P yeah, it's like an ATM machine or a PIN number
Fire the director. Moving shots do not belong in an educational video. This isn't a promo selling a whizbang or a cooking show. Excessive cuts are distracting to the ability to absorb this information. I usually love your videos and the content here is great, but the video direction is not appropriate and the editing not conducive to learning.
Dwight Awesome Agreed, This would only work as a refresher course, but for a new learner of the material, it’s too difficult to follow comfortably.
I liked your comment for your use of "whizbang"
Actually, it IS a promo, selling a battery. They aren't even good batteries, they're well marketed batteries. 2 year lifespan on those spiral cells. I know because I sell people XS Power batteries to replace their 2 year old Optima batteries.
Would be interested in seeing a break down of lithium batteries. I have a Shorai lithium battery that weighs 4lbs(!) in my BRZ.
Good suggestion! I’m curious as well.
+1 for Shorai
Tell us more about your BRZ...
Ballistic makes a 4-cell 12v Lithium Iron Phosphate motorcycle battery (EVO2) that weighs less than a pound. I used it in a converted motocross-bike-turned-supermoto and literally strapped the battery inside the airbox it was so tiny! It worked great in that application and cranked a modified 450 4-stroke with ease, although the 8-cell would be a better choice for most street bikes and those are still under 2 pounds.
What's the CCA on those???
As of today, our three cars have all had new batteries in the prior 12 months. It's always a pain when an otherwise reliable car needs a new battery, to say nothing of incidentals (some batteries are tougher to remove than others). I'll probably start using AGMs on cars we expect to have around for a while, instead. Great vid! I've been wondering about the hype, but now it's much more concrete to me.
Informative video. I dont like the constant camera shifting, though. It kinda feels like a marketing video for a car or something.
I purchased a yellow top today. I wasn't sure at first but later I remembered you made this video, and I was sold!
Engineering Explained it's ok my dude, sponsored vids make me a little sad as well...
You look a lot less happy than usual on the set.
I ran across your channel a week ago, been looking up things for my 13 STI I just got. I think I’ve watched them all. Thanks for the explanations on everything. You make it really easy to understand!
Happy to hear it, thanks for watching!

Good info but this video felt kind of scripted and over produced compared to other videos of yours I have seen. Kudos to Optima for sponsoring this, but personally, I prefer your home made videos.
Thanks for the feedback!
Dislikes?.. Obviously we are in the day and age where excellent information backed by science and research is frowned upon.
Excellent information as usual thank you for posting.
That Porsche in the background
🙌🙌 So many sweet cars in that Garage. 720S, Ultima GT-R, NSX, and loads of beautiful 911s.

I'm learning so much from these videos, and your simplicity of explanation. This helps me with my engineering designs for various automotive components and actual vehicles themselves. Loving this.
In a garage with all these pieces of hardware and many physical examples... but still uses a white board. Staying true to yourself I see 😁
You didn't see the hardware and physical examples he used?
its too dangerous to be disassembling a battery, it could burn you or cause a fire my dude
The old EverStart Maxx-78S lead acid battery in my truck got me 13 years of dependable use without any maintenance. Amazingly, it could start the truck after sitting months at a time (that was a pretty common occurrence too).
Been waiting for this video ever since I saw the pictures from it months ago. Always wanted to know the differences between those two types of batteries. Awesome job!
Thanks!
I’ve been through 3 Optima yellow top 51R batteries in the last 5 years… never again…
Optima were good batteries at one time now they are making them poorly as many have also stated here and on countless car forums .. I went with an Odssey battery and so far so good.
@@space_114v2 Odyssey is the way to go. Their parent company, EnerSys, acquired Northstar in 2019 so they’re really the best batteries money can buy. I’ve always suggested those two and now they’re made by the same company so even better! Plus they have a 4 year full warranty on all their batteries haha
optima used to be made in the USA and had stricter quality control standards... they built a new factory south of the border and let their quality control go... they are not the batteries they once were, and I too won't waste the money on them... the company was sold and the new company is making money off of the previous companies good name while running it into the ground. They won't be in business long at this rate.
Informative as always; however, I am not a fan of the new "cinematic" film style. I prefer just the white board
Appreciate your feedback, thanks!
I can always respect someone who freely shares knowledge
So if you are partnered with Optima, you are now under a fiduciary responsibility to paint the company in the highest light possible.
Optima batteries last about 6 months at most
@@errornull390 i have a redtop Optima which dates back to 2013
Optima batteries are fantastic, I've got 1 in each of my historic cars. One is getting close to 9yrs old and still cranking strong, the other is in a 4x4 pickup that might see use once a month or two without problems for the last 5yrs. ..both yellow tops.
Great description, keep up the great vids. ...and the white board
Johnson Controls is the manufacturer of most automotive batteries in North America, currently making Optima, most "store brand" batteries, some of Interstate's batteries, and a lot of OEM equipment, too. You really have to go out of your way to not buy one of their products.
Cars Simplified I think their AGM's are okay. The flooded Johnson batteries can't handle the desert heat. The battery posts eventually cake up in like 2 years. Never seen an AGM do that from them.
We've used Optima batteries for years!! The only way an old style lead acid battery comes on the place, is if we get new equipment... currently, we have about 40 Optima batteries in use...
In the last year, we've started using the heavier Yellow top starting/deep cycle batteries... They hold up better in the service truck and in the semis.
Good video!! Well explained!
One advantage I didn't hear you say is.. corrosion is pretty much non existent with the Optimas... We always make sure everything is clean, cover the terminals with dielectric grease... Zero issues!!!
We used to clean everything, then paint the terminals after connecting them... It seals the connection and works also.
This is markedly harder to follow than videos past. Background music is distracting. The white board made differences easier to follow throughout. Sponsorship fail.
Good info thank you! Here in AZ the water filled batteries do not last at all in our summers and I end up topping them off every couple months in the summer. I put an AGM (not Optima brand) in my truck a few years ago and have been very happy
Remember, AGM and Flooded need different alternator voltages. Swapping these will over or undercharge the incompatible battery. So change the voltage regulator to maintain compatibility.
A huge Thank You to Optima's videography!! Best quality (visually speaking) you've ever produced. ...also I'd wear that shirt every day, I've been a long time proponent of Optima's technology. I have a RedTop from 6/08 that's been in 3 different cars through 2 summers in FL, 3 winters in WI, 4 years in TX + more. Stoked you now have this connection in your journey!! ....cheers mate (p.s. ..I seriously need one of those shirts)
Well produced and entertaining advertisement.
I like how a lot of people are telling you ways to make your sponsored content more effective instead of complaining.
Absolutely LOVE this. Such an informative video. I like how you drew everything out.. that way, can see it better in my head rather than just being told. I’ll always love my optima battery and will def keep pushing to sell them at my job. They’re much better quality!
Good technical information. My first and last Optima died after almost a year, was replaced under warranty and that one also died in about a year. I bought an Advance Auto AGM and it is almost three years old.
Weight differences between the 3 batteries? Would also be interesting to compare to a lithium battery
That’s a good question. I’m not sure on the actual weights, I would imagine for the same weight, the pure lead will offer better deep cycle and cold cranking characteristics. I have a couple sitting in my garage, I shall weigh them!
They aren't too different, I've handled both. Spiral cell optimo batteries are fairly compact, so easier to handle than some batteries
Dear Engineering Explained, I have noticed the quality of the video has been dramatically improved. I like the "less static" flow of the video and more editing/animation put into it. Cheers and keep it up!
Very cool interesting video I've always wondered about this. Thank you👍
Happy to hear it! I was always curious about it as well, it was interesting to learn about!
Is this still engineering explained or just an Optima commercial?
I like your channel and I understand if you mention sponsors that provided equipment, testing facilities etc., but I do not want to see a six minute commercial about something that you could have explained better without Optima.
What about LiFePo batteries or other AGM designs?
Why not mention their advantages?
So glad someone did a breakdown on these battery. Always wanted better but heard rumors that customers had bad experiences with optima batteries.
I failed to learn anything from this video because the format 2oo distracting.
okay.
Yup they kept switching camera Just when he was explaining.
Not his usual style though
Thanks for making this video. I've been using Optima for atleast 10-12 years now. Zero issues, I even have one in my camper.
Good overall video, not in love with the background video and the constantly changing camera angles
He kind of sold out. Optima used to be a great batteries before they were sold in 2009 and closed their plant in the USA. Now, they are made in Mexico with inferior parts.
I work in a battery production plant, this video is little bit older by the time i am making this comment. Johnson Controls sold off the battery division, it is now called Clarios. Optima batteries quality has diminished a bit since they moved production to mexico. Overall this was a good explanation of internals of the different types. Keep making videos, you doing great job.
Looks like my E36 M3 is getting yet another early Christmas present.
Such a sweet car!
Engineering Explained Thanks! That it is. It needs an Engineering Explained decal haha Keep up the good work!
Thumbs up for Optima batteries! I've always used the yellow top for my car stereo needs. They will help with the lights dimming on hard bass notes. My old 2000 watt amplifier liked to kill batteries about every 3 months but this one lasted til I sold the car. It was over 8 years of abuse.
TIP: when you are not looking at the camera, we shouldn't be looking at you. So when you are explaining something on the board, going back and forth adds negative value.
Ray Foss he means stop jumping between the shot of him and what he’s explaining, WHILE he’s explaining it
Yeah the jump cuts were super annoying when I was trying to look at the board.
This is a paid promotional video, not one of his standard videos, so I suspect the editing was not entirely under his control.
TIP: understand what you're seeing before you say anything about it. If you've seen ANY of his other videos for more than three seconds, you'd immediately recognize that the only part of this he had to do with was being there to speak. The irritating editing, lighting, and background music are very much likely out of his control.
+illitero I've been here for a while. TIP applies not matter WHO is doing the editing. Point still stands.
Wow that new flat plate agm battery looks great! Very aesthetically appealing. Goes very well with the overall square design of most muscle cars. Now all they need to do is offer different colors for all the battery types and they would be unbeatable.
Let's say I purchased a yellow top Optima battery. If the car won't turn over and the battery seems dead, and I need to get somewhere immediately due to an emergency or other reasons, can I use a traditional battery charger that most of us have in our garage (on max output setting voltage or amps) to charge this battery like a traditional flooded-lead battery?
What about short and long term risk from this event?
Yes, can charge exactly like other lead-acid batteries.
Wrong. You need a agm battery charger, or daisy chain from another battery to the optima.
We did a test with our Police fleet and found the Optima batteries life expectancy was 1 1/2 to 2 times that of flooded lead acid batteries but the price was 3 times higher. The Optima's performed about the same but they did have a lower cold cranking amperage ( 750 CCA vs. 850 ) and lower reserve capacity (120 vs. 150 ) then the flooded lead acid batteries.
Please name the flooded one¨s brand, as I would like to find out a cheaper option for normal, cheap cars. My experience with Optimas here in Finland that they last 4-10+ times the flooded ones do. Actually, all AGM batteries last so much longer than flooded ones, if you find one that physically fits your car or truck there is no reason to buy a flooded one.
With your fleet, what may have been the reason for so little margin, usually Optimas are hard to fit to the place of the original; I had to modify the battery tray/box of my H3 to fit a suitable size (electrically) Optima. Usually only electrically "smaller" optimas fit original battery trays, so it is apples to oranges unless the situation is made fair.
I always love your explanations but these camera movements and obscured angles are super distracting
I have a small mat-type battery for my garden tractor, and it has out performed the other two regular batteries I had before. It's still working fine after several years of Wisconsin's freeze/thaw cycles.
A FLA battery is 2.1V per cell not 2.2V with resting/fully charged voltage of 12.6V not 13.2. AGMs are usually around 12.8V. You also could have discussed acceptance rate during charging in that AGM batteries can be charged more quickly as they can accept more current.
theshimonmor yup 12.6 =fully charged
i put a red top optima in my 07 Xterra once the old factory battery was getting funky.. and it starts up quicker and is great. Plus they're not that expensive compared to other regular batteries. I'm glad i switched it up to the optima. Great video as always.
Great explanation, as always. The editing is really bad, though. EE's usual videos emphasize the actual explanation of the topic, and this feels extremely like the sales pitch it is. Maybe they should've just let him do his usual routine with sponsored content.
Haha, I will keep this in mind, thank you!!
Optima batteries last 6 months top
I saw some negative comments below from people that feel this gentleman took the easy way out from doing true engineering to do TH-cam videos. Well let me say this about that. He is sharing his knowledge and obviously likes to teach. As a fellow engineer with 30 plus years of experience, I personally feel that it is wonderful that this man is "GIVING BACK" and sharing his knowledge versus some people that are self-absorbed and never make any contribution in life what-so-ever. If he makes more money doing this then in traditional methods, kudos to him. Today you need to strike hard and strike fast to secure you place in society and TH-cam has afforded him with the platform to do so. Regarding the keyboard warriors out there that love to comment from the safety of mom's basement, stop typing and get out there and do something with your lives rather than playing the role of the critic. I can tell that with 35+ years of hard work in the real world, it can be very rewarding!
so you recommend agm?
Optima has been running the agm battery game for. Over 2 decades from what I remember and I been using optima since I’d say my first car in 2008 never looked back 2
Enjoyed the content but didn’t like the constant cuts to you then back to the diagram. Much harder to follow than your usual you at the whiteboard format. It doesn’t add to the delivery rather it distracts. Love your work
Thanks for the feedback, I’ll definitely make adjustments in the future!
Engineering Explained your diagrams are great and I scan them absorbing whilst listening. When the cuts jumped to you I found myself stopping listening because my head was preserving a sort of mental bookmark of the image. Then trying to catch up. Anyways, keep up the good work
I really wish you were my teacher when i was going through my mechanics courses... You would have been the best teacher
I quite dislike the editing in this video..... we dont need to have strafing shots and scene changes every 3 seconds while he is describing something and demonstrating it on paper..... honestly its not only silly looking, but it actually distracts from what he is doing cause you keep shifting the focus away from the topic.
Criticism aside though, good video content, I have always wondered what the difference was.
Thanks for your feedback, definitely noted that it was distracting to many, and I'll address this in future content! Thanks!
I should also note, It was spicifically distracting when you are doing the in deth explanations/demonstrations on paper. there were many situations where it did actually work, like when you were shoing the actual products exc.
Experimentation is good :P
Engineering Explained Good Guy Jason doesn’t throw the editor under the bus
I really don't care about the change of angle as I was not paying attention to these angle changes. My ears are focused on hearing the content but my eyes drift multiple times to that distraction of a candy red car up in the lift. Having the Porsche is a "convenient inconvenience".
Excellent video, very informative. However, unlike the rest of the EE videos, I had to keep rewinding and pausing to read the captions. They were there and gone in a flash, and it was difficult to concentrate on what was being said and reading the added info at the same time. I'm glad this isn't a common format for EE!
Nice content, but the multiple camera angles and editing were very distracting. Keep it simple! Oh, and delete the annoying background music!
I didn't follow this video as well as your other videos. I felt lost and wanted to look at the visual aids more. Thanks, man. Really like your stuff
Me: Tries to understand drawing*
Video editor: No
This video isnt biased at all. And i love how it shows the drawing for .5 seconds at a time. (Sarcastic of course)
Do AA Duracell batteries work?
Great for flashlights! 😂
Oh that’s good because I don’t have headlights so I duct taped flashlights to the hood instead 👌
Only if you have enough of them. ;)
Only if you have 6400 of them.
Like 800 in parallel and 8 in series.
So with a lot of duct tape can work
Electroboom used AA batteries to jump start his car. He had quite a few of them though
~5 years ago got the round 55 Ah Yellow Top and alongside with it 4A Defa battery charger. The Yellow Top is more expensive than regular batteries, but it's absolutely worth it!
Month ago it was -30°C here and I didn't have preheating on. Took 3 short cranks and the car started - couldn't do that before with regular FLA.
Great explained!👍
As a battery specialist, do I agree with Jasons simplified explanation of the differences?
Yes, well done Jason.
Great video
Thanks!
I know the video is fully sponsored by Optima but i don't care, it's good for you and us.
Thanks Jason!
Hate the editing in this video. And no cons mentioned? Gotta pay bills somehow
I bought my MGB 9 years ago with a 6 year old Optima Red. It still charges well and with 15 years on it has 12.5 at startup. I am amazed it is still working like new with 15 years on it.
What I don't appreciate about this video Jason is that you did not state any disadvantages of the "alternative" designs of batteries vs the conventional flooded lead acid ones. There must be some. And this made it too obvious that its just a "Pay to show our product" sort of video with little objective value.
The main purpose was to demonstrate the chemical differences. Like anything, you get what you pay for; AGM style batteries are significantly more expensive (the disadvantage).
I get that, but the message in this video is basically - The battery that is probably in your car is not as good as this Optima one, buy it. Im sure there are more disadvantages in that design other than just price. In today's level of technology it's always about tradeoffs. And even if it was just the price, mentioning it in the video would be appreciated.
Keep up the great work. These are just my two cents in form of (hopefully) constructive criticism.
Unfortunately, this video did come across more like a paid advertisement than one of his normal educational videos. The optima golf shirt he was wearing contributed to that impression as well.
Hey EE, I watch a lot of your videos and love the way you explain technical issues in a way that's clear and understandable to the average person. Two comments on this video: 1. you got a few things wrong here. Minor details but this is my speciality professionally so I noticed. 2. It was probably a mistake "partnering with Optima" for this video - but that's my opinion.
What about maintanence free lead acid batt??
Also known as a SLAB (sealed lead acid battery). Yeah, what about SLABs?
The alloy used typically in a flooded lead acid battery is antimony(1-4%). Replacing antimony with calcium gives you a maintenance free battery. Advantages of calcium include improved resistance to corrosion, no excessive gassing, less water usage and lower self discharge. The case can be sealed so the small amount of gassing can condense and return to the cell.
I love my daily dose of David Schwimmer teaching me about cars
Geez, it's 2018. Why aren't we using LiPo?
I never heard that li-po are used for large application 🤔
Because it's more expensive, doesn't like being stored fully charged, internal resistance can go up quite rapidly over time and it requires way more "management" than a lead-acid battery increasing not only costs of the battery, but also battery management electronics.
Lipo batteries have many issues. For example, they can't tolerate sitting fully charged for extended periods of time. Lithium batteries also need intelligent management systems, which would add cost, complexity and points of failure. They don't tolerate heat either, which is a big problem for an automotive battery. Another major problem is their environmental impact. Lead acid batteries are nearly 100% recyclable, and you get paid for them. Lithium batteries, however, are much more difficult to recycle, and they are expensive to dispose of properly. Recycling a lithium battery costs more than you'd make off the materials, so a lot of batteries would probably end up in landfills. Another major issue is safety. If a lead acid battery gets overcharged, it damages it and may leak acid. However, if a lithium battery gets overcharged, especially a large enough one to be used in a car, you have a fiery bomb. Same goes for the battery getting crushed in an accident. All in all, 25-30 pounds of weight savings is not enough to replace lead acid batteries with lithium batteries in automotive applications.
Excellent as always.
As a personnal experience with Optima Battery, mine was a Yellow Top and was 12 years old in my car (I say was, but you'll see why). Got a bit of audio that needed a better battery.
Sold the car (hence the was) with the battery still in it (a,d the audio). Did a test of the battery before selling it : 100% charge ok, and still giving 100% of the voltage ! Never had to recharge it !
Really good quality, and I will go again with Optima on my next car.
I can't trust someone's review of a product if they are wearing a logo of the brand
I keep buying Optima Yellow Top batteries but I have never had one last more than 3 years. My last one only lasted 8 months. However, I am not giving up yet. They power my stereo system very well.
Wooow very bad video
Did not like this technique in any way
The good thing about ur videos have always been ur easy to understand well thought out graphs and pics but the way optima took them for u was really bad
PS not saying in anyway that being sponsored by optima s bad it's cool af
Way to go Jason
The music was unnecessary and I would prefer it slower at your natural, uninterrupted speed. It was a good video though and I am happy for the company to sponsor the video.
Waldemar Stelmach yeah u summarized my point more accurately lol
Even the sponsored content is 99% informational. 👍
i have had an optima for 7+ years and it's still going strong
a 7min. for a 2 second answer. you never disappoint me
