I'm going to keep spreading this. A 9 volt battery jumped to the dead battery while attempting to charge worked for me.
It's ridiculous that a battery charger won't charge a completely dead battery. That's the idea of a battery charger to charge a dead battery.
I could not agree more my friend
Nothing last forever my friend. The average life span of a battery is 3 to 5 years. Once the the battery expires its time for a new one and it won't hold a charge
@@jeromemeyers4167 I'm merely talking about a new or recent battery that has gone completely dead and the battery charger won't charge it. It doesn't have to be a bad battery it could be a a battery that's just completely drained. Older manual battery chargers would charge a completely drained battery.
"Smart"? More like dumb battery chrager
I had this problem last year. took the battery into my warm house ..... hooked it up to my battery booster pack 3 times for 20 secs at a time .... throws enough energy to trick the "smart" charger to begin its cycle.
If you have a booster and are out and about and you find your battery is dead flat ... of course hooking the booster up will not start your car. You must first disconnect the battery cables, then, hook the booster cables up only to the disconnected cables ..... bi passes the dead battery, starts every time.
I HATE the microprocessor controlled chargers! I actually threw out a good battery because my new Stanley charger stopped charging after a few seconds and went to a zero-effective, never ending "Reconditioning Battery" state. I let the NEW battery on my seldom used farm truck run down again and yep, the Stanley said "NO." After watching your video I realized that if I supplied enough voltage, the charger would sense the battery and charge it. I used the Engine Start feature on the Stanley. It supplies a heavier charge for 60 seconds. After about 10 consecutive Engine Start cycles, my battery had enough voltage to be sensed, and it charged perfectly Thanks for the "lead!"
Thanks for this video. Worked like a charm. Tried to charge it with a "smart" charger for two days with no luck. This had the battery charging in no time.
the battery in my Corvette was dead and my battery tender wouldnt recognize the battery, this worked and helped a ton! thanks!!!
I once put enough charge in a dead 12V car battery using a 9V PP3 battery, it added just enough power to get the smart charger to turn on. I read it somewhere, tried it and it worked.
After trying to charge a 3 ,1/2 year old battery ( with a warranty of 3 years) , I tried for 2 days...nothing . Just about to spend $95 on a new one, and found this video. The battery is now fully charged, brilliant fix thanks
I do something similar. I 'briefly' touch jumpers from good battery to totally bad battery. 1 second or less in case dead battery has short, etc...Then I disconnect and just attach charger to dead battery. More times than not, the quick connection above will bring the voltage high enough on your battery to get the charger going.
Thanks so much! I just tried to charge my motorcycle battery with my smart charger and it would not change. Used your trick and I am up and running! Thanks...
Thank you for this video. I followed your instructions and it went from refusing to charge to fully charged. Thank you!
That's great! I'm glad this video helped you out! Thanks for watching!
Good Lord! My intelligent chargers will try down to 9 volts.
I have used alarm panel batteries to trick the charger to just get it started charging for mowers and such.
Very helpful video! Thanks for sharing!
So glad I came across your video, my son's motorbike battery had 0.5v in it which meant my Optimate 2 would not start charging. Wired the bike battery up to a car battery then clipped the charger to the car battery and after 3hrs had 6v in the bike battery and now it's on charge direct with the charger 👍🏻
Thanks from Australia. My battery is dead, and I couldn't remember the jump sequence. This works great
Thanks for tip. Exactly what I was looking for.
Wow! This worked amazingly well!!
Thank you!
This worked perfectly. Thank you for the helpful idea
I’ve always had a spare car battery good solid crank on timber blocks on the ground and still using old school trickle charger to this day. I’ve looked after it extremely well.
Hook up fully charged high crank battery to any dead battery in a car or motorcycle or anything and bang kicks it in the guts.
Anyway thanks for the advice
Thank you, just what i needed!
Good video, it was informative. Merry Christmas!
Can be done with two intelligent chargers PROVIDING that at least one has the option to do an engine start. Hit the battery with the engine start then hit it with the ‘intellijunk’ charger. I tell you one thing. Even if it takes a knife fight i am never walking past a 1980s schumacher battery charger at a garage sale again!
Comment of the year right here! That is awesome! Thanks!
Y are those the cream of the crop ?
@@cr112784 they just don’t have this ‘smart technology’ and their construction is better.
I remember being a kid and seeing what my dad and others used as battery chargers: a box on wheels that let you choose 2amp, 10amp, and 50 amp settings. I've seen better ones with 100 amp ranges. When that thing came out, dead battery problems were solved, very quickly.
It blows my mind that we live in a world where it is perfectly acceptable for products to decline in quality and capability.
Thanks for the video! My B&D "smart" charger had never failed me, but it just kept clicking off when I attempted to charge my Chevy Silverado dead battery which had been setting idle for over three weeks! I followed your video using a "ghost" battery removed from my private aircraft and it worked like a charm! (I first tried a 9V radio battery, but couldn't get that to work.) Thanks for the "tip" and the very clear and easy procedures for the fix!
I'm glad to hear it worked out for you! We've got to help each other with all these "smart" chargers these days.
Thanks for your podcast will try it out in a few minutes
Just done this. Great advice. Thanks for sharing. Some idiot left his key in the ignition switched on. Doh! 😎
I may try this method, as the charger I bought won't charge since my mother's battery is 0.2v currently. Thank you for the tips
Worked like a charm thanks
Great video, thanks for posting! I had two RV batteries hooked up in parallel on my camper. I forgot to disconnect the leads when I put it in storage. Therefore with the parasitic drain from the camper, it drained my 2 batteries down to 1 volt. I thought, no problem. I'll hook up my smart charger. The batteries wouldn't take a charge. I got my 2000 watt portable generator out and it has a 12v connection to hook up to your battery. I hooked it up and ran the generator for about 10 minutes or so. That was just good enough for my smart charger to detect a enough voltage to start charging. I was thankful, being those 2 batteries were only a year old. These smart chargers are a PIA!
😊
This is excellent help. I have a battery in my Subaru which is reading about 11.7 volts and which is not enough to turn the engine over. The problem is that I have bought a new Ring smart charger to replace my old broken non smart charger and the new charger is not recognising the battery-even at 11.7!. I had thought today that the new charger was faulty but in order to prove/disprove that, I shall follow your steps in this video to see whether it's the new charger at fault or whether the battery is simply not at a voltage which the charger will recognise. Thank you.
I wasnt aware that smart chargers had a minimum voltage requirement for charging ! Hmm... Lets see what we can do about that now after having watched this very instructional video :)
Thanks! I just bought a viking "smart" charger but my battery is below the threshold (10v). I also have a travel viking battery jumper. I'll use them together. So ridiculous lol 😅
On some smart chargers the "bad battery" light may be more of a tell-tale than something that cuts power. I figured that much because the aligator clip on a Duralast charger was still sparking. If it wasn't trying to push any current, it wouldn't be doing that. I figure they may still switch to a different mode however (even lower charge rate?), to play it a bit more safe.
So if it sparks with a bad battery indicator, it's still doing something.
So you have to have a good battery to charge a dead battery with a smart charger. What good are they ? So if I’m sitting at home with a dead battery and no other batteries around I still can’t charge my dead battery. I guess that’s the new American way. Good information Josh.
Yeah, these new battery chargers are garbage. I have one old style left that will throw voltage into whatever I connect it to.
I absolutely hate the new style chargers, but it's all you can find these days. It took me a bit to figure out this workaround so I thought I'd share for anyone else in the same boat.
I've seen the threshold voltage on these chargers as high as 12v. If I have 12v on a battery, it really doesn't need charged.
Brilliant lesson & thank you my friend! To me it looks like the manufactures of batteries And chargers are in cahoots & simply taking the piss out of the pubic and just trying to screw us for every single coin we have in our already empty pockets!
Used my Harbor Freight jump pack to fool my old Die Hard charger to run in manual mode. Then, I got enough voltage on the battery that I could get my new Vector battery charger to do the rest.
Going to give this a try, I've got a 6/12 volt smart charger. It will charge a dead battery at 1 or 2v but only to 6v. It must have to read higher for it to realize its a dead 12v.
Thanks for the trick
The smart thing about smart chargers is that when the battery is charged, they will switch to float, maintenance or storage mode and not boil out your battery. The dumb thing about dumb chargers is that they are like the Energizer bunny, they just keep going and going. So you have to watch them. They are useful for some purposes. You could use a dumb charger to put a "surface charge" on your dead battery in a few minutes that will allow your smart charger to engage. You can also use a dumb charger to desulfate a battery if it's not too far gone if you do some research and understand what voltage and amperage levels to watch for. Good video.
Hey, thanks so much for your awesome hack. Silly question, but do the batteries need to be the same kind? My dead battery is a calcium and my deep cycle is AGM?
I'll try it. Have a big farmer battery that is dead, brand new never used it. Want to sell it, gotta charge it up first.
Groovy video.
also if the battery charger says bad battery then you can also use the boost option on the charger for 30 or so min and then put it back on the charge option
That's a good feature that some of the better smart chargers have.
I've done this many times and it does work by tricking the voltage however I will advise you that one time I did this on a 12v battery that was at 5.5 v and few hours later the battery took off in my yard good thing I have big yard and charged it away from my house or garage 🙃..The cause was my charger was damaged somehow from doing this method I thought the inline fuse would or internal components would've just burned out and stop charging I was using a Ctek charger.
Thank you.
I put charger to dead battery. then cables from helper battery onto charger clamps. Once charger fooled I can take jumpers and good battery away. Good battery could also be another good car to fool charger. I did have a modern charger with an overide button. It was great until I backed over it. Shit happens. Sometimes I use old charger to fool new charger then disconnect.
like using new chargers when I wont be around to disconnect. thx for video as it will have helped many out there. Canada
Great vid, thanks.
Would you recommend doing this with a completely drained battery too?
It's not detected by my charger - which min. limit is 2.5v - so I guess it's somewhere between completely drained and >2.5v.
Cheers
Yep. I've done this on that old suburban after letting it sit for a long time. Battery voltage was basically nil and it brought it back from the dead.
You should run the positive charger lead to the dead battery and the negative to the good battery so that you are not decreasing the life of the good battery. Still fools a smart charger but does so in a better more efficient manner.
That's a good idea too
I'll be doing this in the morning, so after doing that do you attach one jumper cable to the posts left on both batteries to complete the circuit?
Thank you for this video…I have a Promaster Van…😢Simple question….When you connected smart charger to good battery…how did you have room on the battery posts to connect both jumper and charger clamps? Please don’t laugh at me…this is my first attempt at being a car mechanic….These batteries are very expensive so I have to try!😊 Thank you for your help!
Good trick.
Some "smart" chargers do have an override function but most don't.
It's ridiculous!
It ranks up there with the new gas cans!
I learned about this charger problem when I picked up a smart charger at a thrift store with no owners manual...it didn't charge my battery and when I looked into it I learned what was going on.
You can actually just temporarily attatch a 9-12-14.4 volt small battery just long enough to fool the charger and then remove the small battery and that usually works.
A 9volt alkaline battery can work sometimes or a drill battery or whatever just get the polarity right!
And remove it after the trickery!
And again some chargers have a way of overriding the detectable voltage feature for a short time like 5 minutes?
Read the manual!
Or keep or buy old school chargers!
I bought an old style battery charger today.
The receipt was still in the box. It was bought in 1979.
It's now charging my totally dead battery.
I got my hands on an older manual charger this week also. I opened it up tonight to go through it and check it out, but so far all is looking well with it.
@@TheWeekendAngler I've now charged two totally dead batteries with it.
The best £5 I've ever spent.
Anyone else looking for a manual charger, I haven't found any. The best option I found is harbor freight's analog style charger. It requires 7V on the leads but you can google the hack that puts a switch between 2 solder joints so you can bypass the 7v safety mechanism.
@@thebluelunarmonkey I got mine from Facebook Marketplace.
@@thebluelunarmonkey Harbor Freight just released a manual charger. I saw it at the store yesterday when I was there. It's about $50. I think I'm going to buy one and try it out and do a review video
Fing genius!
A way with less effort is to get an old 12v wall wart power supply, and a splitter ( one male, 3 female outlets) for the cord, clamp the charger leads on the battery, then the wall wart leads to those clamps and turn on the charger. The charger will sense voltage, so will start to charge. Once it starts charging you can disconnect the wall wart power supply and the charger will run until the battery is fully charged.
I've done that one before also. Good tip!
Thank you for explaining something that has confused me for years. Always got it running, was never sure how. I have a trickle charger. I am guessing the 2 volt trickle aspect of this charger is disconnected from the " smart". Throw a trickle at it for a couple minutes and presto, it works. Turn it up and away we go.
I originally thought I found a magic hook up point after fooling around for hours. Then my magic wouldn't work one day. I am too stupid for this smart crap.
@@Thea-gj2or I liked the chargers a lot better when they were a simple transformer and rectifier. They'd throw voltage into a rock if you wanted them to. These new chargers are horrible.
@@TheWeekendAngler I was ready to smash things so many times. I learned at a young age that smashing things just gets you smashed things. We don't drive the car often enough or far enough to keep the battery charged. It gets worse in our - 20 degree winter lows. Lasts a month at best, then the struggle begins. I think I have it under control now. I might actually understand the problem thanks too you. Thanks again for the explanation and the swift reply. Dave
To clarify, the day it didn't work was yesterday. By trickle charging it for 3 minutes I got it to charge at 10 v. Now the charge rate is dropping fast. At 7.5 v and dropping. Started the car an hour ago but wanted a better charge for the wife to leave the house. I am convinced it will read full charge very soon. Thanks for helping me understand why, hopefully. I only say hopefully because I thought I understood it before. Good times on you and yours.
my battery is now 4 yrs old.. if it's my car does not start, all i just do is to connect wires in parallel to another car then start, for the alternator to charge my dead battery.. after a while, my car can start and i leave it 10mins to charge up itself.. then good to go 😁
Instead of hooking the Dewalt to the john boat battery connect it to the dead battery. Then just piggy back the other leads temporarily onto the dead battery. Then when charging starts you can remove the john boat battery and your Dewalt is already in the right place.
This is also an issue with the 18650 and likely many lithium ion batteries. Some of my chargers will get past the low voltage, won't charge issue, but most would not. The remedy is the old type transistor radio 9v or probably any 9v. Use it the same way as explained here, and your off to the races. As mentioned in my prior post, unless someone can prove otherwise, something is VERY fishy with today's chargers.
Yep. Make a charger that won't charge and you can sell people new batteries. Plus, since the analyzers at the stores will show it good, since it is, they don't have to warranty it. I wonder how many folks have bought batteries they didn't need.
Smart charger, you mean smart ass charger.
Let me know when you make a video to how to remove the smart
Just buy a NOCO Genius brand charger. It has a “force” mode that will manually charge batteries under 1V.
I run noco genius onboard chargers on both of my boats. I did this video for people stuck with the "smart" chargers.
Yes i killed my 2 year old battery and my charger will not fully charge it, I knew about this trick but I forgot it can't wait to hook another battery to it a charge it up , thanks.
Even a small 9 volt transistor radio battery will make a smart charger begin charging. Once the charger turns on it will continue charging after the small battery is removed.
9v is usually the accepted threshold voltage for charging, however a lot of the cheaper smart chargers require a little more.
I've got one that won't charge anything under 11v.
Why don't these chargers have a bypass button? In the meantime, avoid DeWalt.
I like dewalt tools, but this is one of those cases where some fly-by-night company paid a little money in exchange for being allowed to put the dewalt name on their charger.
I have seen a few chargers that do have a manual mode, but not very many.
This is fucking genius
Will this work if you're using a smaller 6v/12v everstart battery charger?
It should.
A charger refuses to charge an 11.5 volt battery then, seriously, wtf good is it???
How you do the voltage almost at end of this video when had the red and black in oil that to volt meter
I'm not sure I understand your question, but I connected the red and black volt meter leads to the side posts on that battery. That is a dual post battery, with posts on the top and the side.
It only helps if you have another good battery
I still keep a dumb battery charger around just to get the initial charge on the battery.... same idea.
Then use the smart charger to finish it off.
I buy dumb chargers almost every time I see them for sale at yard sales or auctions.
Do u need to take out the good battery out of your car or can you just leave it in the car connected
You can leave it in the car connected.
could you use a jumper instead of another battery to make think the charger its 12 V?
No. You have to have a 12v source for the "smart" charger to turn on.
You can jump the dead battery for about five minutes and get a “surface charge” on the dead one then your charger will recognize it and begin charging.
so a "smart" trickle charger won't charge a dead battery? What exactly did the makers of these "smart" devices think they were built to do?
They expected people to rush out and buy their "Fancy" chargers that are much cheaper to produce since they don't require large, heavy transformers.
Will it work if there is no charge left in the battery. You had 11 volts in the suburban
I've used this method before with batteries reading under 1 volt.
Would it make sense to try this from one vehicle to another rather than jumpstarting?
That would work. I'd probably connect the running jump vehicle to the dead one and allow about 5 minutes. The running vehicle's alternator will likely put a surface charge on the dead battery which will be enough to trick the charger into coming on and finishing the job.
Isn't it dangerous to leave that setup on very long as it will over charge the good battery??
You're fine to do it for the time it will take to get the depleted battery over the smart charger threshold. It won't overcharge.
so what's the point of having a battery charger if you need to keep a fully charged battery around?
You didn't used to have to until they started making these "smart" chargers that are dumber than a brick.
Better still, buy a smart charger that will bring up a dead battery to full, I bought one for this reason after my previous smart charger couldn’t do it. Now I have one that will pump in the amps like the old transformer type and then float it afterwards. The smaller units aren’t worth it.
this is probably a dumb question; but is it possible for a dead battery to read fully charged and keep shutting of the smart charger? ......Thanks, Willie
It is. But that's usually an indication of a defective battery. I'd suggest having that battery load tested to get an indication of its condition.
@@TheWeekendAngler thank you
had battery tested and the volts were good but no AMPS, resulting in a bad battery......
@@bonniejohnson1518 that's the downfall of flooded lead acid batteries. Once the plates sulfate, the battery is pretty much finished
The problem now u are charging 2 batteries, not one time and energy wasted as well as now it may stop charging prematurely because of the good battery in circuit.😊
How are those Dewalt chargers? I didn’t know Dewalt sold those.
I wouldn't buy it a second time if I had the option.
I have the DeWalt DXAEC80 dual bank charger. It's good too with a pretty good desulfate cycle. Charge, desulfate for a 24 hours, repeat charge and desulfate 3 times. It does require somewhere around 9-10V on the clamps before it will charge, maybe I'll open it up and feed a 12V thru a 2k resistor and a switch to the + clamp to bypass the "safety".
And people don’t think about this so you have a dead battery but you don’t have the money to purchase a battery charger but you need to leave in the morning to go to work, so do you have a old cell phone charger take a cut the end off strip it back you’ll see a red and a black wire Hook it to your battery plugged in overnight and your batteries charged it’s like a trickle charger used fast charging one, so what it takes all night but you didn’t have the money to purchase a charger and this is actually charging your battery the correct way the way it should be done. You don’t want to charge your battery fast you want to take it slow and bring it up And bring it up to fast it’ll never charge your battery to 100% people don’t think compromise things around the house it’s just laying there and I know people have thousands of cords and ends for the wall socket plug it into extension cord and there you go or go to Harbor freight spend $15 get your solar panel so when the vehicles off The batteries being charged during the day that takes a strain off the alternator system because the battery is fully charged a lot of people don’t think and you run it directly to the battery and leave it hooked up all the time so when you’re going down the road is being charged your alternator shuts down because the computer sees the battery is fully charged Savon gas saver on the wear and tear your alternator and battery I think people forgot how to think.
These chargers aren't 'smart': if they won't charge a completely dead battery, they're dumb as hell....
Can I charge a standing car battery using a battery on a moving car?
Hooking it up might require some acrobatics.
@@TheWeekendAngler ahahahaha I think he meant charge a loose car battery with a running car using jumper cables. I’m wondering your opinion as well for deep cycle batteries.
@@sacm.d.l8337 this technique will work for deep cycles as well.
@@TheWeekendAngler sorry I meant just forget the battery charger and use the car’s alternator. Like jump starting a car but no car. I’m a bit nervous to try it but Ive been in a tight spot sometimes where this would have saved the day. Didn’t have jumper cables with or I would have just tried it.
@@sacm.d.l8337 you can use the alternator output of a running car to charge a separate battery, yes.
What is the point of a battery charger if it wont charge?
These "smart" chargers are anything but.
Can you connect the charger cables to the dead battery instead in this arrangement?
It's worth a shot, but more often than not the charger will read the dead battery and refuse to engage.
But if you have to do all that what's the purpose of the battery charger that's why we buy a battery charger to avoid all that
That's why I still keep an old style manual charger around. Easy way to tell is quickly clap the leads together. If you see sparks, it'll throw voltage into anything you connect it to.
What the heck is the point of this idiotic "feature" ? I mean it's so idiotic, many would consider such charges defective and should be returned. Enough returns would put a stop the issue. Call me paranoid but the only thing that comes to mind is the charger is designed to give the impression your old battery is ruined so you buy another. If anyone can come up with a better theory, I'd love to hear it.
Yeah, that's ridiculous.
You gotta have access to another battery or another car, to make a battery charger work.
That's not very "smart" if you ask me.
However what is definitely "smart" is that many of these "smart chargers" are sold with trademark names such as Diehard. What is Diehard famous for selling? Right. New car batteries.
Techs can use these smart chargers to force a customer into buying a new battery even if their battery could have been saved. "Sir, the charger wont even detect that your battery is hooked up to it. You need a new battery." Despite the battery being new enough to be resurrected. (but what shop wants to resurrect batteries as a favor when they could just sell new ones for profit?)
Smart chargers are the dumbest thing ever invented. If the battery voltage was up enough for the charger to detect it it wouldn't need to be charged.
You're absolutely right!
It’s because of you have a bad cell you’re not creating an unsafe condition. Usually batteries below 10.8v are junk or need to be rejuvenated
smart chargers apparently only charge fully charged batteries
Pretty much. I think the person who coined the term "smart" on these chargers was anything but. 😂
so you need a charged battery to charge a dead battery.. that is absurd.. we should be able to trick the undervoltage relay.. I will look for it..
Some chargers you can. I agree, it's a nuisance.
So where can I find a dumb charger? I got 2 of these worthless smart chargers.
Facebook marketplace and garage sales is about the only place.
Just used a 9v battery to do the same thing
I'm going to have to try that. That's an awesome hack! Someone else mentioned that a few days ago too. Thank you for sharing!
@@TheWeekendAngler it sounded ridiculous when my buddy told me but it worked within 30 seconds and my battery was dead dead. But it just has to register something with a few volts I guess even a small ass battery will work
Thls is an old method called "piggy backing".
11.4 WON'T CHARGE??? SEND THE CHARGER BACK TO THE MANUFACTURER I AM FEED UP WITH HAVING TO "JUMP" A BATTERY TO GET A CHARGER TO WORK. MY LAST OLD STANDBY JUST BIT THE DIRT SO I AM LOOKING FOR A NEW "REAL" CHARGER.
Facebook marketplace is the best place to find older chargers
its too late. the 100w bulb hatchet has fallen on the traditional always on and doing something chargers. while i dont have the glass blowing skills to make a century bulb i can still put some old iron and a rectifier in a box. what a divergent technology to unload on the unsuspecting masses who simply left a light on overnight. now you want me to buy a booster pack and sell it to me in iphone style packaging. your running real low on chances to fool me in the future, battery charger cabal.
I still snatch up traditional style chargers when I catch them for sale. But they've gone the way of the dinosaur.
If you have jumper cables, just ask for a hand and if someone pop their hood and jump your battery so the alternator can charge your battery. If that's not an option call roadside assistance especially in colder weather. The issue here is he purchased a 12 volt 3 stage charger but needs a 4 stage charger to get the battery back to 12 volt range. It's a solution however that entire setup is unnecessary and costly. What happens when the backup battery discharges down to 11 volts. You'll spend half a day charging batteries. 1200 watts at 30a bulk stage 3 hours per battery.
what a load of crap i did that and the only battery that charged was the good one the dead one stayed dead
It sounds like you may have had a defective battery. Sometimes they fail internally and they simply won't charge anymore.
This hack is useful when you do something like leave a dome light on overnight and deeply discharge the battery.
Thank you so much .
There is a nice people like you in US ? 😮
Biden give us a very negative idea
I'd venture to say most Americans are friendly people, my friend. The news says things to try and make us look and feel more divided than we really are.
@TheWeekendAngler Hardly to believe it if you support someone not like you, it's not my word it's a UN meeting.
You truly act like you found something new that has been known all you do is hook another battery up to it let it sit there for a few minutes and then hook your charger up and the smart chargers are much better because they charge a battery to a full 100% at stages they slowly charged up instead of fast like the old chargers did and you cook the battery, fry it in with a smart charger when it’s fully charged, the charger automatically shuts down with the older chargers. They didn’t start out slow and then slowly step it up they would is ball those battery plates and you would sell start smelling the acid Stinkin and when you smelt the battery like that you knew you had something going on had a bad cell that battery was done smart chargers are made for safety reasons and the newer batteries are sealed Joe batteries non-serviceable. I actually like the smart chargers because they bring your battery back in a full hundred percent where it should be because people have this bad mistake of charging the battery just enough to get the vehicle started and then they take the battery charger off that batteries never fully charged and they think all the vehicle do it while you’re putting a strain on your alternator and one thing people don’t realize a lot of Fords if you have a low battery and you jumpstart that vehicle that battery is not a full hundred percent y 100 percent in one thing people don’t realize that battery is not fully charged up. People have a bad habit of just starting a vehicle and going well. The thing is on a lot of Fords especially the older ones GM’s and the newer ones that batteries not at a full hundred percent and you start that vehicle guess what you just took that alternator immediately to go buy alternator now he blew out the regulator and a diode’s. That’s why your battery needs to be at a full hundred percent charge before you start a vehicle. people are in a hurry nowadays go go go they got time the way. Oh they’re in a rush. Learn how to settle down and wait a minute as you get older, you’ll realize a lot of things you’ll start settling down, slowing down and think how old that old guy he was right but you won’t admit it when you’re younger just a dumb technician telling somebody a little advice and they think they know it all I know because I’ve done the same thing after working on these vehicles for years and years I learned the batteries not at a full hundred percent good way to spike the system because the alternator is not seeing a full correct voltage it increases the volts amps. It’s like a power surge takes it take a big chance of spike in the system doing more damage to your vehicle than what it’s worth and guess what that’s a thing that’s not under warranty you have to pay for it. There’s no warranty coming out. There’s gonna pay for that, once a technician figures out what happened get your wallet out time to pay up so just do yourself a favor go to Harbor freight get your solar panel. You can’t do that you got plenty of cell phone chargers, laying around cut the end off it’s got red and it’s got black hook it up to the battery and plug it in and go to the house, you could leave the cord up on the hood and if you’re scared disconnect, your negative, then plug the cord in but that little bit of voltage it’s like a trickle charger. I don’t know why people don’t use common sense no more compromise.
If I have a good battery and jumper cables, I no longer need a battery charger for any reason whatsoever. I have numerous trucks, GM and Chevy, in the years 2000 to 2006, and they all developed battery drains. I don't have time for these garbage "smart" chargers at all. These engineers go out of their way to complicate things and solve problems which do not need solved. The answer to having a battery which can start a car under any circumstances is to have a "dumb" charger which charges batteries, not scolding yourself about leaving a dome light on and saying "oh well, this is my fault and i deserve to be punished"... Charging batteries was never a problem. Why is this even a problem? Because all of you let it happen. You buy garbage products and think this is normal.
I don't need my charger to be "smart" or to micromanage tasks that I need to resolve. Charging any type of battery in any condition and in any circumstances was guaranteed to occur. If you had a charger, and a dead battery, you would be able to start your machine. Now we have chargers which won't even tell you on the box that it only charges batteries which currently have a certain voltage. So now chargers are hit and miss? Old chargers would charge any battery, while new chargers pick and choose which batteries to charge based upon some arbitrary standard which is done by some engineer creating extra digital circuits into the device to limit what it is allowed to do. Why are they doing this? Not to help you out... Hahaaaa ... A battery charger which doesn't charge batteries, THESE SNAKEOIL SALESMEN ARE MANUFACTURING AND SELLING BATTERY CHARGERS WHICH DO NOT CHARGE BATTERIES!!... AND PEOPLE ARE BUYING THEM AND LOVING IT!... amazing... Hey, I got an idea for something that people will friggin love: SMART FLASHLIGHTS. I will design a flashlight which will allow you to control many features of light generating technology, like lumen concentration, ambient wavelength recognition and control for the sensitive eyed person, brightness control to keep things illuminated at a constant level regardless of the time of night. However, this flashlight will not work in complete darkness. Why you ask? Hey, if you will buy battery chargers that kinda work as long as your battery is kinda charged, but not at all when you need it the most, then you will surely buy a flashlight that will kinda work as long as there is some kind of light already present, but not at all when you need it the most. Ooh, my brain is storming, I'm gonna be stupid wealthy from an entire line of "smart" gizmos: fix-a-flat ((but not if you're all the way flat), air conditioners (but does not work in desert conditions), sanitary tissue wipes (but will not clean up body fluids), clear eyes (common side effect is irritated eyeball), tattoo parlors (corner the temporary tattoo market by just not telling anyone up front, kinda like how these battery charger guys fail to make any mention that their chargers will only temporarily charge as long as your battey already has a charge), deodorant sticks (only works for people who smell like roses to begin with, and fails to work if you are active for more than 5 minutes), ink pens (the pigments break down after 10 minutes)... Okay, I'm done.
This is stupid needing a good battery well how about you dont have one?
Blame the idiots who invented these types of chargers.
I keep an old manual battery charger around for when I have an extremely dead battery.
@TheWeekendAngler I know living in an idiocracy. Yea just found this out.
@@androidtexts6948 it's crazy, brother. These smart chargers work great for keeping a battery topped off, but most of us only drag our charger out when we've done something dumb like leave the lights on all night. Lol.
Then, we expect our battery charger to work but end up with this stuff. That's one of the reasons I made this video, to show folks a way of getting their car or truck battery back to charged. Granted, not everyone has an extra battery available, but the ones who do...
I had to charge my car with my other car a few minutes to get my charger to work...charging now
So the idea is that you need a good battery on hand to start the charger that’s meant to charge the dead battery. Smart battery chargers are not so smart & whoever created these “smart” chargers should be recognized and shit on for literally going backwards. Older battery chargers were fine and could charge a dead battery but now a diy to fix the smart charger is to have a whole other completely healthy battery somehow have it on hand if your car decides to shit on you & not start, then trick it that it’s got 12 volts out of thin air or unicorn tears or just so happen to carry a few 12 volt battery spares 😂. I thought the idea was that the dead battery doesn’t have anywhere near that range but maybe common sense isn’t so common nowadays lol
