I am not at all good with cars, but I have an older one with a battery that keeps draining. I bought a charger and all the videos I watched were horrible. You made this as simple as it actually is. Thanks.
your battery should indicate AGM or GEL on the label. If you charge these types on the standard setting, you will dry out the battery and drastically shorten the lifetime. AGM and Gel batteries use aa charging voltage of 14.5 volts whereas a standard (flooded) battery typically charges at 16 volts If you hear a liquid sloshing sound inside your battery, it is a standard type battery. AGM and Gel batteries do not have free flowing liquid acid in them. It is either bound up in a glass mat material or it is in gel form If you measure the voltage while the battery is still charging you will probably ready the charging voltage and not the battery voltage. You won’t know the battery voltage until the charger is disconnected for a few hours. Then you should measure 12.4 to 12.6 volts when fully charged
Quick instructions, liked that, did not have to wait through a much of nonsense, he explained all the settings, that was great. I had started to watch another utube and the man did not know anything.
The one thing you didn't say was how long yet the title says how long. If the battery is a 110 ah charging it when it's flat at 2amp will take at the least 24 to 48 hrs (depends how flat), overnight will not charge it fully and a partially charged battery is next to useless.
Great info! I have an older gauge display setting charger w Boost mode or Charge mode. Didn't know what full charge setting was at. Now I know, 12.4 to 12.6 volts, set at Charge mode to trickle charge. Bounce around other channels but yours was what I needed and well explained. Thanx!
I have a Schumacher charger/maintainer like yours with all of those features and did not understand some of the features like the 30 Amp charge after watching your video I have a complete understanding of how to use it thank you
Thank You! 8/23/2022! $75 for a jump! My first charger ever, Trying to stay home to save GAS! I did not think to disconnect ! Old dogs still can learn a trick.
A lead acid battery is empty at 12.0 volts and is full charge when left ten hours of the charger after a full charge and volts should read 12.6 volts this is for and a brand new battrey and older battrey may drop in volts much more quickly after a full charge and may only hold a voltage of 12.5 volts or less depinding on the condition. Aslo a older battrey will get to full charge faster . because of sulfation on the plates .
lead acid battery is 50% state of charge, but i realize with most deep cycle its recommended to not use more than 50% and starter batters should not dip below 90%.i am not sure why in the video when he showed the display it read at 12 volts while being 100% soc. mine shows the actual real voltage and i have the same charger, it likely would be 14.4v until i disconnect the charger and let it rest and i find 100% soc is 12.7v. the sulfation reduces capacity, the less capacity is why the cc/cv cycle of the charge is done quicker, essentially your battery just gets little smaller in watt-hours as it wears out or takes damage then it can escalate the rate of decline in terms of even more lose of capacity measured, most accurately in watt hours, but sometimes measure in amp hours. but the volts should be the same, no?
Thanks man, you deserve way more subscribers to be honest. Multiple ways for the process that you covered and easily explained as well. keep up the good work.
@@JPAutoFleet Nice video there! Very useful. I have a smart battery charger and what i don't know is if you need to open the caps on the battery while charging. Can you help me?
I would have thought a fully charged battery should be about 12.6 volts, batteries are sensitive, cold temperature affects the operation of a battery greatly, when batteries start to lose charge after a few years use its because sulphanation is occurring on the plates. This sulphanation would not occur at all if the auto working voltage were say 15 + volts as opposed to the 14 to 14.4 volts currently used but battery manufacturers need to sell batteries, batteries have been around a long time and have not changed greatly since then
My 7-year-old battery has been reading just over 12V after the battery light went on the other day - but the alternator is only putting out about 11.8V. Slow-charging the battery got it to 12.23V at 80%. While I work on that crazy-tight lower alternator bolt tomorrow, I'll have the charger on to see if it reaches 100%. But 7 years - that's Costco for ya.
Thanks! Sometimes when I need to do things like these by myself without someone else, I try to find a good video that will teach me how. To tell you the truth, kind of scary since it can go horribly wrong if not careful.
I have a Schumacher SE-1052 with 50 amp engine start, 10 amp fast charge and 2 amp slow charge settings. It has an analog needle gauge to indicate both the DC amp draw and the percent of charge in the battery. The charge amperage tapers down as the battery nears full charge.
How long will a car battery's charge last with a constant 2 amp draw, and how long can it take a car battery to fully charge after start up, charging by it's alternator?
All depends on how frequently your driving/starting it, and the length of time it sits without being started. I can't give you an exact time but a 2 amp draw will drain the battery fairly quickly over time. As far as how long it takes to charge back up depends on how much it's been drained. But usually, 1 hour is a safe bet. Hope that helps!
Look at your battery as a box of energy, and as long as you are comparing 12v batteries, the size of the box, called the capacity, can be compared by the battery’s Ahr rating (the ampere-hour rating). So if you have a 24 Ahr battery, it can supply a 2A current for 12 hours.
@@JPAutoFleet , thanks for this video. I used my car to jumpstart a friend's car, and now a day later, my car won't start. I'm assuming my battery needs to be charged, but I'm wondering if you have any insight into what I should do. Thanks!
A charger that does 5 amps or 10 amps is a much better choice for most people. Lead acid batteries like to charge at approximately 0.1C....an 80 Ah battery would be ideal around 8 amps. 2 amps is slower than necessary and 30 amps is way too fast. CTEK MXS 5.0 and Noco Genius 5 and 10 are my preferred chargers.
Hey there, I picked up a charger like the one in your video at a garage sale and realized later the cable connecters had been replaced with identical nickel plated clamps. Is there a simple way to determine which cable is positive? Thank you! Your video was clear & easy to comprehend btw.
I basically had the same problem with my battery. Last month when I was on my way to the store, my car died so I got my multimeter out and I checked the voltage on the battery and it was 9.7378 Volts so I thought “what the heck is going on with this battery”, the next thing I knew I seen some smoke coming from the tips of the battery terminals. I was suspicious on what was going on and I couldn't believe it because this battery was only barely 16 years old which I consider fairly new in today's society, so basically what I want to do is try to clean up the battery with some soap and salt solution and then I might put it on the charger for two or three minutes at a high current rate just to see if it will hold a charge. I'm not sure if that's going to help the battery or not but one thing's for certain before I go out and buy a new battery, I'm definitely going to try these two methods that I suggested. Now on the other hand I could swap the battery out with one from my 1962 Chevy Tahoe but I'm not sure that my old lady would let me do that, so basically what I need to do is first, I'm going to check all the air in the tires before I monkey around with the battery. Then I'm probably going to run a few errands around town down and the next thing I want to do is get some paint and paint the battery terminals because I don't think they look very good without the neon yellow color look on them. If all goes well, I am planning to do a few other things to the terminals. Next after that chore, is get some of that distilled water and pour on the outside of the battery to try to clean up a lot of the dirt and dust its accumulated over all these years. If I have time what I'll do after that it's try to clean both sides of the mirrors on my 1965 Ford Bronco because I've noticed while I was driving that it's hard to see what kind of traffic is coming up behind me. I was having a problem with the battery when I put the headlights on low beam and then when I tried to switch the high-beam I noticed that the voltage excursions were jumping around so I went out and I bought another set of test leads to use on my digital multimeter and there was no difference at all, so I think I may borrow my friend Tony Jones's multimeter just to check those voltage excursions to see if that is normal. Nobody really explained to me how to test a DC voltage excursions when the battery is not in its prime. I am all on my own doing this. A lot of people have contacting me and they said that they've had that problem once or twice and maybe even three times in their lifetime with their batteries but they did something totally different. What they did was loosen the terminals first then they carefully remove the battery and hoisted it out to get rid of all the debris and dirt that's accumulated after all these years then they put it on a slow charge which I believe they told me was 32 milliamps for 6 days, 3 hours and 54 seconds. Next they took the battery caps off and added some distilled water, which they claimed that they bought it at their local Walmart store. I think, if I can remember correctly, they said it was .99 cents plus the sales tax. Can you believe that just 99cents? That's a real good price for one full gallon of distilled water. Speaking of water, yesterday I helped my neighbor that lives to the right side of my house, fill their swimming pool for the new season. It literally took 7 hours to fill. I am not sure how many gallons it is. I have met people in my lifetime that had no idea that there were 4 quarts of water in a gallon jug. They just assumed it was a gallon only. I am not really good at math but I do have a calculator on my cell phone. Speaking of math, it takes me back to grade 11 in high school when my teacher, Mr. Lowry gave us a sneak quiz on algebra. I failed it because I didn't understand what that was all about. I spent most of my high school time stoned and kind of out of it. Some of my classmates were very good at math, and it even showed when they got their report cards. I may have gotten of the path of whatever we were initially talking about. I think it had something to do with blue cheese. No, I remember now, it was car batteries. I never could figure out why they put car batteries in the front of the vehicle and not inside the vehicle. It would be so much easier to work on them, especially in the rain, if they were inside the vehicle. Doesn't that make more sense to you too? Well anyhow, batteries are pretty heavy for their size and some people can't lift them very good. I had a fried, Tony Smith who had asthma and once he tried to lift out his car battery, and sneezed, and the battery fell out of his hands and landed on his right baby toe. It broke the small bones in that toe of his. I called his mothers step daughter Ann but she was not home. So I then called his brothers uncle Fred and told him about what just happened to Tony's toe. He seamed like he was drunk and started laughing at me and said “I don't care about that Bast#rds toe”. I got mad and hung up on him immediately. From that day on, I never spoke to Tony's brother's uncle Fred. I never really liked him in the first place because when Tony and I were 13 years old, we were at a softball game and Fred walked over to us and farted right in our faces. That was not very nice of that old pervert. I heard some stories about him when he was about 20 years old that would make you cringe if you heard them, but I can't get into that right now because I have to finish up my posting here on you tube. I hope I have given you folks some good advice on having some of your problems solved in a timely manner. I like to help out when I can if it is at all possible. I am out for 3 more hours so I want to go now and get a hot dog and a bottle of grape soda. I need to look around for a ride so I can get back to my padded room at the Sinclair Insane Asylum. I hope Dr. Dilbert will not be mad at me for sneaking out....
Such good information, thank you! Taking all this info into account. Who knew? Not me! I had been having a problem with periodic dead battery, but it's my short trips and low speeds (15-20 mph) urban driving. Understand now that I need to charge the battery, not just start the car-so one question. Will a standard extension cord, the orange kind, work for this?
Thank you, very helpful! I have another question. How do i know if my battery or alternator is the problem? I was driving on the freeway the other day, when my battery and brake lights came on intermittently. I started loosing power and once I got off the freeway (I thank God that it happened then when I was also close to home rather than while I was still on the freeway), all the electric system shut down and my power steering too. Then at the first stoplight where I had to stop, my engine stopped too.
It's more than likely your alternator. If the battery was bad and you had a good alternator, the alternator would of kept the charge up and the car wouldnt of died. Just to be safe take the battery in to bd tested at the parts store for free. The battery will probably need to be recharged. Theres plenty of good videos on TH-cam on testing for a bad alternator. It's a simple test you can do with a multi meter. Hope this helps and thanks for the comment.
Mine doesn't have the built-in protection feature but just yesterday quick charged it for thirty minutes. Charge and load tested using harbor freight battery tester and it was good. Them quick charged it for another 15 minutes . Yeah it has three settings emergency, quick and trickle rate . I never used emergency thinking if I'm not careful could damage it. Also used trickle rate when I can wait hours even overnight.
i have been charging my batteries for testing purposes a lot these last few weeks and i was using the "30 amp boost". i just saw in my manual 5 mins ago and you just confirmed i was using the wrong mode. that is why my batteries were over charged to 15 volts lol. also my application is i am learning about solar power, battery banks and inverters, but at night when i get home from work its dark and i have no sun, so i use the wall charger to get the battiers back up. no one should follow any of my adventures as of yet as i dont know what i am doing which is why i am watching this video. side note i have the exact same changer but mine is the autozone branded model, seems to be the same, just a different color and name slapped on it.
Sorry for my ignorance; how long does a fully recharged car battery last for, does it last for a couple of years as if it were newly bought or for a few months? I tried it looking for that answer online, with no luck.
Here is my question. My wife' vehicle has been starting fine with no issues . The past 2 days we got 10 and 15 degree days and go to start and it won't start. Does this mean the battery is bad or weak cells? I just put the charger on it but not sure if this will help going forward if we get colder temps again.
Excellent video but one question. Why is the second choice 30 amp, that doesn't make much sense to me. My charger second choice is 12 Volt that's what I usually use when I need to use it.
Hi, thanks so much for the video. How long does it take to recharge the microprocessor controlled charger through a household outlet? And can the charger be used as a power source? (ie. Does it have outlets?) I'm thinking of getting one for my camper van which has an Optima Redtop battery (AGM). I'm hoping to use the van's main battery for appliances within the vehicle for short periods of time, perhaps through the cigarette lighter with an inverter, unless you have a better suggestion. My only concern is recharging the battery, if I'm not driving it. Any tips would be greatly appreciated! Thanks so much
You dont have to charge the microprocessor Controlled charger. You plug it in and then hook it up to your battery for charging. If your asking how long it takes a battery to charge that depends on how Depleted the battery is. Often times over night with this particular charger. It doesn't have outlets. If I were you I'd have a second auxiliary battery installed and run all your appliances off that. Youd need a deep discharge Optima blue top battery for this. Take it to a shop and have them mount it and wire its linked to existing main (starting) battery. The main battery will then charge it when the vehicle is running. This way you can use all your appliances pretty much whenever you want. And you wont compromise the vehicles starting system due to a weak battery. Hope this helps!
@@JPAutoFleet Thanks so much! So if I do that, will my power bank be comprised of both batteries? Or will the appliances only draw from the blue battery? My concern is indeed unknowingly draining the starting battery and having a dead van. However I got the red top optima thinking I could use its power for more than just running the van. So a way to monitor the battery level so it doesn't die, or cap it before it does, would be ideal. Thanks again for all your help, I really appreciate it.

If a battery gets limited use, put a 1 amp maintained charger ($30) whenever battery isn't being used. Example: tractor/mower during winter.
My 7-year-old battery has been reading just over 12V after the battery light went on the other day - but the alternator is only putting out about 11.8V.

I think it had something to do with blue cheese. No, I remember now, it was car batteries. I never could figure out why they put car batteries in the front of the vehicle and not inside the vehicle. It would be so much easier to work on them, especially in the rain, if they were inside the vehicle. Doesn't that make more sense to you too? Well anyhow, batteries are pretty heavy for their size and some people can't lift them very good. I had a fried, Tony Smith who had asthma and once he tried to lift out his car battery, and sneezed, and the battery fell out of his hands and landed on his right baby toe. It broke the small bones in that toe of his. I called his mothers step daughter Ann but she was not home. So I then called his brothers uncle Fred and told him about what just happened to Tony's toe. He seamed like he was drunk and started laughing at me and said “I don't care about that Bast#rds toe”. I got mad and hung up on him immediately. From that day on, I never spoke to Tony's brother's uncle Fred. I never really liked him in the first place because when Tony and I were 13 years old, we were at a softball game and Fred walked over to us and farted right in our faces. That was not very nice of that old pervert. I heard some stories about him when he was about 20 years old that would make you cringe if you heard them, but I can't get into that right now because I have to finish up my posting here on you tube. I hope I have given you folks some good advice on having some of your problems solved in a timely manner. I like to help out when I can if it is at all possible. I am out for 3 more hours so I want to go now and get a hot dog and a bottle of grape soda. I need to look around for a ride so I can get back to my padded room at the Sinclair Insane Asylum. I hope Dr. Dilbert will not be mad at me for sneaking out....
I really liked your straightforward factual presentation.
Such good information, thank you! Taking all this info into account. Who knew? Not me! I had been having a problem with periodic dead battery, but it's my short trips and low speeds (15-20 mph) urban driving. Understand now that I need to charge the battery, not just start the car-so one question. Will a standard extension cord, the orange kind, work for this?
Thank you for answering the question!
Thank-you Josh for the very common sense explanation!
Thanks man for the demo...very helpful and ez...
Glad it helped you out👍
Good vid, hacks like this are very helpful!
Thanks man, you solved all my doubts. Well explained.
No problem. I'm glad it help 👍
@@JPAutoFleet I use Marine battery charger on car battery. is that ok?
Thank you so much for sharing your knowledge you rock I now know how to operate a battery charger
Thank you, very helpful!
I have another question. How do i know if my battery or alternator is the problem? I was driving on the freeway the other day, when my battery and brake lights came on intermittently. I started loosing power and once I got off the freeway (I thank God that it happened then when I was also close to home rather than while I was still on the freeway), all the electric system shut down and my power steering too. Then at the first stoplight where I had to stop, my engine stopped too.
It's more than likely your alternator. If the battery was bad and you had a good alternator, the alternator would of kept the charge up and the car wouldnt of died. Just to be safe take the battery in to bd tested at the parts store for free. The battery will probably need to be recharged. Theres plenty of good videos on TH-cam on testing for a bad alternator. It's a simple test you can do with a multi meter. Hope this helps and thanks for the comment.
Mine doesn't have the built-in protection feature but just yesterday quick charged it for thirty minutes. Charge and load tested using harbor freight battery tester and it was good. Them quick charged it for another 15 minutes . Yeah it has three settings emergency, quick and trickle rate . I never used emergency thinking if I'm not careful could damage it. Also used trickle rate when I can wait hours even overnight.
Super clear and helpful thank you bro
Thank you so much! This was very helpful.
Thank you so much for this video. It helped a lot 🙂
Thanks for the video! very well explained.
I use a NOCO 10 for charging and maintenance. Just connect and forget.
Thanks for the video, I assume a standard battery is a calcium? I have a 2015 Liberty/ Legacy with stop/start
You are a good teacher! Thank you
i have been charging my batteries for testing purposes a lot these last few weeks and i was using the "30 amp boost". i just saw in my manual 5 mins ago and you just confirmed i was using the wrong mode. that is why my batteries were over charged to 15 volts lol. also my application is i am learning about solar power, battery banks and inverters, but at night when i get home from work its dark and i have no sun, so i use the wall charger to get the battiers back up. no one should follow any of my adventures as of yet as i dont know what i am doing which is why i am watching this video. side note i have the exact same changer but mine is the autozone branded model, seems to be the same, just a different color and name slapped on it.
Keep tinkering brother. That's how you learn!. Thanks for the view and comment
Thanks. Good advice on how to recharge a battery.
good info thanks J.P.
Well explained..i was wondering what type of a charger to use..i will now buy 2amp.
Thanks glad it cleared things up for you
Great Vid 👍🏼
Sorry for my ignorance; how long does a fully recharged car battery last for, does it last for a couple of years as if it were newly bought or for a few months? I tried it looking for that answer online, with no luck.
Very helpful info. Thanks A LOT!!
Here is my question. My wife' vehicle has been starting fine with no issues . The past 2 days we got 10 and 15 degree days and go to start and it won't start. Does this mean the battery is bad or weak cells? I just put the charger on it but not sure if this will help going forward if we get colder temps again.
Do I have to remove the battery from the car using the charger you suggested for a DIY at home?
Thank you. This was very helpful.
Thanks always helpful !
Good vid, very useful
Thank you for the info!

Thank you!
No problem!
Thanks JP that was helpful
Great video 👍🏻
With a 12 volt charger, what is the difference between charging at 6 amps or 2 amps?
Which amperage should I charge on?
Excellent video but one question. Why is the second choice 30 amp, that doesn't make much sense to me. My charger second choice is 12 Volt that's what I usually use when I need to use it.
Good video ,very helpful
Hi, thanks so much for the video. How long does it take to recharge the microprocessor controlled charger through a household outlet? And can the charger be used as a power source? (ie. Does it have outlets?)
I'm thinking of getting one for my camper van which has an Optima Redtop battery (AGM). I'm hoping to use the van's main battery for appliances within the vehicle for short periods of time, perhaps through the cigarette lighter with an inverter, unless you have a better suggestion.
My only concern is recharging the battery, if I'm not driving it.
Any tips would be greatly appreciated! Thanks so much
You dont have to charge the microprocessor Controlled charger. You plug it in and then hook it up to your battery for charging. If your asking how long it takes a battery to charge that depends on how Depleted the battery is. Often times over night with this particular charger. It doesn't have outlets.
If I were you I'd have a second auxiliary battery installed and run all your appliances off that. Youd need a deep discharge Optima blue top battery for this. Take it to a shop and have them mount it and wire its linked to existing main (starting) battery. The main battery will then charge it when the vehicle is running. This way you can use all your appliances pretty much whenever you want. And you wont compromise the vehicles starting system due to a weak battery. Hope this helps!
th-cam.com/video/1JkH8sH_uK0/w-d-xo.html This will help
@@JPAutoFleet Thanks so much! So if I do that, will my power bank be comprised of both batteries? Or will the appliances only draw from the blue battery?
My concern is indeed unknowingly draining the starting battery and having a dead van.
However I got the red top optima thinking I could use its power for more than just running the van. So a way to monitor the battery level so it doesn't die, or cap it before it does, would be ideal.
Thanks again for all your help, I really appreciate it.
@@Beaming246 Mainly just from the blue battery. It's the perfect solution. Do it!
Thanks! much appreciated.
Thanks...this is very helpful
Glad you thought so. Thanks for watching!
Thanks, very informative
For sure my man🤜
