*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 kzread.infoUgkxcJ22tnHH9l1vjdIdEIG27iOG55P7LXI8 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!

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.

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 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.

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!

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

I've got a whole box full of batteries for recycling I;m going to try this trick on. Thanks so much for posting this!

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!

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?

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.

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

You saved me from replacing my pack of 4 AAA. Thank you!

luv you....i shocked the dead battery by using the remaining ones

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.

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 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

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. KZread is a great reference to find these tricks to fix stuff.

You can also just touch positive to positive and negative to negative with the batteries you don't have to use a wire

I almost threw away 8 rechargable batteries. This worked like a champ. THANKS!

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.

Thank you sir, I just saved a new Duracell AAA 4pack using your method

Thank you so much for the excellent advice!!!!

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 👏

Can't believe this actually worked thank you so much

What is that device you're using to provide the "shock?"

Thanks. It worked for me. I just connected it for 30 seconds once and the bad battery could charge again.

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.

So much waste through the lack of knowledge, thankfully we have people like you who will spread your knowledge

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

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.

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 just saved my rechargeable batteries. 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 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.

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.

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.

Worked like a charm! Major "thank you!!"

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!

This is very helpful video.

Wow it really works! Thanks alot saved me alot of none working batteries 🔋

It works! I just placed some AA batteries in a line and used some wire.

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.

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's the device you used to jump-start the batteries?

THANKS -- you just saved my CR123A pack of rechargeable batteries!

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..

Thx. Worked perfectly.

Thank you for sharing

This actually worked, thank you.

this one is really useful, thank you.

what a life-saver. thanks

Genius. Thank you!

It works on my dead batteries. Thanks

What’s the name/thing you use to shock the bad rechargeable battery? Where can I buy one? Thank you

Works!!! just do it 10 times 2 secs each time, sometimes if you do it to quick do not works...

Thanks ,it worked for my two one.

Very helpful thanks!!!!!

I think this actually worked... Well done man.... I used my Fluke that worked...

Thanks you SO much for this!

Thank you for the tip! 2 are good to charge, one is dead, better than nothing.

Very helpful!!

great video! big thumbs up

Yes! It worked. You Rock.

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.

Wow man it worked. Thanks

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

You made my day, thank you.

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.

What set up did you use to shock them? Just a battery pack with testing rods hooked up to them?

Cool! - I've got the same charger - thanks ;)

fantastic bro

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.

U a legend I taped my batteries together one needed to be charged one was ded and it made them both charge

Awsome worked a treat.

There are many types of battery chemistries...does this work on all kinds NICD, NIMH etc?

It would be interesting to mark the batteries in question and see what the service life will be after this test.

How did these batteries last ?

Thanks so much for this video -- I was throwing out all the rechargeables that said "null" in the charger. This is so simple and works great! Thanks.

Genius !! Does it work the same way for a Roomba battery regardless of Amperage??

Heck yes!! This is a great technique. I used some clamps and spare pieces of lumber to hold my good batteries together and worked great

yes it works

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)

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.

I use a trickle charger meant for a 12 volt auto battery to shock my weak nimh batteries back to life.

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!

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.

You are missing one important step when testing the battery and that was you did not put your meter under load. Try using the multimeter that has a battery test option of 1.5V; then you will see the bad battery voltage decreases dramatically from 1.2V after you jump start the bad battery. Here is the video that will show you how to test the battery correctly: kzread.info/dash/bejne/epedzdyGd5rTfbg.html

How to you make or where do you buy that piece you used to "shock" the batteries?

What did you use to combine the 4 AAs?

What is the thing called that you put the live batteries in to shock the 0v ones?

There are several suggestions for battery reconditioning do not try to do this until you know what you are doing - the acid can burn your skin Test the voltage first - there may be a kaput cell which would waste your time. Check the battery fluid. attempt to fully charge the battery. (I learned about these and more from Jons Mender Guide website )

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

what is the device you used to shock the batteries?

That world for one of my battery, the other wont come back. Thanx for the trip.

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.

Can I use a 12volt car or other lead acid battery to "shock" and 'wake up' another type of rechargeable battery?

On small batteries you can also do the same with a 9V Alcaline battery and a standard clip on😀 connector

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
