*This battery reconditioning program exceeded my presumptions. It worked on any drill battery, several AA and AAA batteries, **batery.repair** and any camera battery. The steps are simple and the act itself is exciting to do. No matter what type of battery you`ve got, it is sure to function again!*
Making use of the ua-cam.com/users/postUgkxcJ22tnHH9l1vjdIdEIG27iOG55P7LXI8 reconditioning plan, I just saved 2 auto batteries from being completely junked. The guides were very simple to follow. I wish I would have found this years ago! You may use the guide to recondition any battery type
I've been saving my old "dead" rechargeables in hopes I could find a way to bring them back to life. I saw your video and am pleased to say that your method worked like a charm, Thanks !!!
When you shocked them, did you do -- ++ or -+ +- ?
This was so great and so easy. I had an old camera battery that refused to charge. I connected it to a 9v battery for a couple of seconds and then slid it back onto the charger and it's actually charging now. Thank you for this!
God bless you ! My cordless drill 14.4 V did not charge any more, so I took a look and was happy to see I could open the battery container ( 4 screws only ). One 1.28 V battery inside was nearly dead with only 0.40 V, I chocked it with a 12V ( 16 V in fact ) as you told + repaired one broken connection between two other batteries, and now everything's OK again ! Many thanks and have a nice day ! Jaybee from New Caledonia
If you're curious, the reason the cell read 0.0 V was because nickel dendrites or filaments have formed inside the cell over time and use, and eventually one or more reached from one terminal of the cell to the other, causing a short. By applying the external voltage from the battery pack to the cell, you essentially burn those filaments like a fuse, and the cell can operate again. No, it's not a permanent fix, but you can try it whenever the cell reaches 0.0V again. Note that if it doesn't read 0.0V, this trick won't do anything. I'd be leery of applying anything over 12V, and certainly only use DC. You always want to be sparing with applying over-voltages, like he said, just a few touches.
ok, but how to avoid such situation in the future? Using the battery more often or ?
I\'m not sure but ,if anyone else wants to learn about nicad battery reconditioning try Jadonite Renovate Battery Buddy (do a search on google ) ? Ive heard some super things about it and my m8 got amazing success with it.
I had a handful of rechargeable AA batteries that I had not used in a while and when I tried to charge them, they would just blink red and had zero charge on them. I was about to toss them out, but I decided to give a quick look to see if there was a way to "revive" them from the dead and I came across your video; I used a 12v AA battery pack I had laying around, loaded up some fresh AA batteries and gave this a try; I was able to save all of them though some of them required about 10 taps or so. Thanks for posting this!
I found it convenient to use a 3-battery holder (of AAA batteries) often found in LED flashlights, for this purpose. Three batteries snap into the holder, producing about 4V at the holder terminals. Install two 4-inch long wires at the ends of the holder (wire ends can be pushed under the terminals with the help of a knife tip). The resulting device can be used as a dead battery shocker, in a way described in the video.
I was struggling trying to make the 4 AA batteries connect together but when all is done, I jump-started my rechargeables batteries like magic :)
thanx for the tip
Thanks dude, revived one of my dead ones. Just by putting 2 charged batteries in line with + against + of the dead one and connected the negative ends with random wire. Got the same charger as you, love it.
I was gonna buy a power bank like that, but why doesn't the power bank recharge a RECHARGABLE BATTERY?
You just saved me 3 AAA and 3 AA rechargeable batteries. Thank you.
I was going to toss 2 AAA rechargeable batteries. You just saved them!
thanks man! I thought my batteries are dead, and after doing your trick they can be recharged again. Before they showed only 0.08V. But I didn't use a pack of batteries, just one fully charged, and it worked too.
What is that device you're using to provide the "shock?"
I thought I just wasted 6 AA rechargeable batterys my battery charger would not stop beeping so I followed your trick and I'm jumping for joy!!! THANKS!
Just saved me some money. Thank you!! I used 2 18650 lithium batteries to revive 2 AA NiMH batteries.
Thanks bro. what a great video. my headphone battery was dead in the water. i took three AA's in series, made a paper tube to keep them in series and touched a piece of wire to the terminals. voila. youre a life saver
Brilliant. Thank you so much for this vid. You have saved me about 14 quid (UK), because my rechargeables were at zero volts. Fascinating.
thanks for the video this has helped me recharge several (dead batteries) that have now been brought back to life rather than throwing them away
Works really well. I don't know why battery chargers don't have it as a start up option. In the past I have ended up recycling them after they failed to charge.
I almost threw away 8 rechargable batteries. This worked like a champ. THANKS!
what's the device you used to jump-start the batteries?
Thanks, just tried it on some AAA NiMH batteries and it worked. I used an old Sony 4.5 volt adapter and zapped them back to life and it worked. I will start a full test on how long they last. UA-cam is a great reference to find these tricks to fix stuff.
And how easy would it be for the charger manufacturer to implement a function that does this automatically a few times when it detects a dead battery to see if it can be rejuvenated?
Surely it would be a simple feature?
Why don't they include it?
You saved me from replacing my pack of 4 AAA. Thank you!
Thanks - I'd given up on an expensive 26650 that was totally dead - Thought I'd search the web in case a bright spark had revived one and came across your vid (actually others first but yours the first with zero volt batteries like mine) and yes, it worked a dream! - Cheers
Thanks. It worked for me. I just connected it for 30 seconds once and the bad battery could charge again.
What’s the name/thing you use to shock the bad rechargeable battery? Where can I buy one? Thank you
Used a rectangular 9v battery and twisted aluminium foil to jump start my batteries... coincidentally also from a long forgotten label maker. Thanks for the help.
Thanks a lot for sharing such a great trick and information about rechargeable cell rejuvenation…hope this will help save a few bucks. You’re awesome 👏
So much waste through the lack of knowledge, thankfully we have people like you who will spread your knowledge
I thought this was total bullshit. I had a bunch of dead 3.7v rechargeable batteries. I tried this technique using a 9v battery. I'll be damned. It worked!!! Thank you, DIY Tinker.
Thanks for this. Had a double a and a triple a battery which had been in Christmas lights. Funnily enough I have a 18650 basic charger. Not a smart one which allows for pretty much any similar battery. It turns off when it detects the battery however after dapping it a few times the light went red to suggest charging. My smart charger now recognises it.
Works perfectly ;) You have saved many many rechargeable batteries. Thank you very much for sharing the knowledge.
Not helpful. It doesn't make sense that the power bank cant charge a RECHARGABLE BATTERY
luv you....i shocked the dead battery by using the remaining ones
Can't believe this actually worked thank you so much
You just saved my rechargeable batteries. Thank you
Thank you sir, I just saved a new Duracell AAA 4pack using your method
THANKS -- you just saved my CR123A pack of rechargeable batteries!
I've just subscribed to your channel because of this video. This is a great video. I am going to recommend this video to people. Thanks!!
What set up did you use to shock them? Just a battery pack with testing rods hooked up to them?
I saw a similar vid before & decided to try, It works. I did this to 2- 18v tool batt that would not charge & charger read bad batt.
Thanks for the advice. I watched your video less than half an hour ago & have just saved half a dozen dead NiMH AAs & AAAs. Instead of using your 2 x 1.5V in series setup, I used a single 3.7V 18650 battery and zapped everything back to life. The revived batteries are all marked with a black X so it will be interesting to see whether they develop any problems in the future.
After reviving several NiMH AA & AAA batteries and using them for a week, one of the AAs & 2 of the AAAs died permanently and couldn't be revived a second time. The other revived batteries are working okay but I will keep them under review to see if they again develop problems..
Darth Dog great job. looking forward for your further observation
Wow! This is superrrrb! I thought im never gonna make use of my 10 pcs 9v rechargable batteries 😭 coz they were not used for more than 5 yrs. But here it goes, the charger's LED is now indicating that it's definitely charging! Thanks so muchhh!
Thank you so much for the excellent advice!!!!
Wow it really works! Thanks alot saved me alot of none working batteries 🔋
I think this actually worked... Well done man.... I used my Fluke that worked...
Nice video. Side note: I have the same type of Brother label maker and decided to go with an optional external power source since this label maker eats batteries alive.
How much did it help medium term? Would it have a similar capacity as expected after doing it? Generally when I have done this the cell would drop again to 0 fairly quickly (i.e. days of intermittent use as opposed to previously weeks of intermittent use)
What did you use to combine the 4 AAs?
Hello. Sorry, I'm a little late to post this. Can you please explain why double the voltage/capacity is needed the 'shock' the non-working rechargeable battery back to a usable state? I've seen other demonstrations where they used just one other good battery, touched the positive and negative ends together, and it was rechargeable again.
This didn't work for me. I essentially tried the same by lining two good batteries plus the bad battery up end to end, then jumping an unfolded paper clip from the positive end to the negative end. No dice. But what did work was putting my bad battery in a charger similar to that in the video, stacking a good battery on top of it so they are side by side in the same orientation. Then I used a paper clip to connect the two negative battery terminals with the charger's negative terminal. Then I used a second paper clip to connect the two positive battery terminals with the charger's positive terminal. Almost immediately the charger gave a reading. Soon after that I disconnected the paper clips and the charger was charging the previously bad battery on its own.
Thank you so much bro! Bought a 4 pack of rechargeable Phillips batteries and 3 of them had 0 voltage. After applying 5v to them just for a few seconds they are now revived!
There are many types of battery chemistries...does this work on all kinds NICD, NIMH etc?
Ok so I had some old dead rechargeable batteries sitting around so I tried this nothing tried a 12 v nothing tried holding 12 v battery to dead battery’s for a minute because I was about to toss them they actually get charged a bit but don’t charge on my charger so did I break the battery or does my charger suck
This is very helpful video.
what is the device you used to shock the batteries?
What is the thing called that you put the live batteries in to shock the 0v ones?
I don't know if those particular Amazon cells are rebrand Eneloops but if they are they shouldn't be completely dead. Unless they were already used alot or they may have been left in a device for too long draining the batteries completely dead. I tried to completely drain an Eneloop, got it to 0.3v for about 15 minutes before it jumped right back to 1.2v
What is the name of that holder you are using? I tried looking for it, but all I can see are similar looking holders with loose wires and I'd like to try tapping the way you did.
Worked like a charm! Major "thank you!!"
It works! I just placed some AA batteries in a line and used some wire.
Hi, I have rechargable Duracell batteries, they don't seem to power anything so I left them in the charger for couple of days. They measure 1.4v but still don't power anything (tried in Xbox controller). They did power a surround sound remote, so seems to be low current output I guess. Can I do anything with them as they are 2450mah NiMH that are pretty useless but we're expensive.
Genius !! Does it work the same way for a Roomba battery regardless of Amperage??
Thank you for the tip!
2 are good to charge, one is dead, better than nothing.
I shocked two of the dead ones that wouldn't charge by placing them between two good ones positive to negative positive to negative. It worked and they accepted a charge.
Can I use a 12volt car or other lead acid battery to "shock" and 'wake up' another type of rechargeable battery?
Works!!! just do it 10 times 2 secs each time, sometimes if you do it to quick do not works...
Thank you for sharing
How to you make or where do you buy that piece you used to "shock" the batteries?
Thanks you SO much for this!
This trick works only with batteries that won't charge at all? What about those which seems to be fully charged but when used they discharge pretty fast? Also, have you tried to do the same thing with 18500 batteries? My rechargable dustbuster works with that kind of batteries
this one is really useful, thank you.
Can i use my motor charger 12volts in reviving my 1.5 triple A with 2700maH Ni-mh battery sir?
You made my day, thank you.
That will work, but the batteries will have very high enternal resistance and low Mah of stored energy because they are aged and worn out.
hi everyone ,if anyone else is searching for restore battery try Jons Mender Guide (Have a quick look on google cant remember the place now ) ? Ive heard some amazing things about it and my partner got amazing results with it.
Is there a limit to how many times you can do this? And if so, is it just gonna become apparent when it's no longer salvageable? Like leaking or bursting or something
Very helpful thanks!!!!!
Thx. Worked perfectly.
What's the name of the thing u use to shock the batteries.
Thanks ,it worked for my two one.
I have several rechargeable batteries that I can charge them just fine, and they show 1.37v after I charge them. But then when I start using them in my noise canceling headphone, they only last a few minutes. Are these revivable? Thanks a lot!
This actually worked, thank you.
It works on my dead batteries. Thanks
great video! big thumbs up
Very helpful!!
what a life-saver. thanks
Would the mobile phone power banks do the same
Genius. Thank you!
Can I do that with a cellphone charger? @5v knowing which wire is pos and neg..
the same trick applies to chargers themselves - as long as they "let in" a tiny bit of charge after "denying" your battery each time you insert it. do this several times, sometimes 5 or 6 (lithium ion for whatever reason - like in the case of power tool batteries - will take tens of times, 20, 30 etc). it will eventually take to it.
U a legend I taped my batteries together one needed to be charged one was ded and it made them both charge
Cool! - I've got the same charger - thanks ;)
fantastic bro
Wow man it worked. Thanks
It would be interesting to mark the batteries in question and see what the service life will be after this test.
+Curiosity thats a good idea. Im not sure which 3 are the bad ones any more, but ill still keep an eye on them and see how long they last.
How did these batteries last ?
What is the largest batteries that this method will work with ?
Where did you get the plastic thing you had 4 AA batteries in which then had a Red and Black connector that you used to shock the battery. i have a battery that has got a charge. when i use my battery tester its at the bottom of the GREEN.
>
I have tried 4 different chargers they all give me an error message. when I try and charge it to max it out so that the battery can't take any more charge it gives me an error. I have 3 different Duracell chargers they give me error. I have a charger large enough to charge D batteries it gave me Error and this Panasonic charger just kept saying the battery was full.
>
I don't know how good it is to use a product where not all batteries have the same amount of charge.
What's that thing called that you used to shock the batteries where can I find it?? What's the name of it or how can I make one??
Do i need to use specific wire?
I got some batteries at 1.35 volts that won't charge in any of my 3 charges. Does this mean they're done?
