Thanks bro I repaired my sick battery after seeing your helpful videos,

Thanks for giving me the courage to open mine up. found a bunch of rusted off tabs and a few dead cells in my two broken batteries. Saved me from buying replacements. Glad I had a few 18650's stashed away.

Fantastic video! I bought a BD 20-volt drill and battery from eBay for $28. They both appear to be brand new. I was disappointed when the battery blinked red. I tried your trick and jumped them for a couple of minutes. Viola! Works great. Thank you very much.

Amazing bro! I bought a “new” drill from someone on fb market place and when the battery did the blinking red thing I convinced them to refund me half the money. Then a KZbin search brought me here and with a $6 9 volt battery I was able to jump start the “broken “ battery and now it’s charging!

Fantastic! Jumped my battery using safety pins taped to the top of a 9V battery for about 3 minutes. No more flashing red, looks like it’s charging! Thank you!

well, not something, I am a woman who does not solder, could do! But at least I have a partial answer. I have two new Black and Decker hedge trimmers, dated 2021, and both flash red. Suggests based on this that they have sat around uncharged for too long.

You should have jumped that battery in the first place instead of pulling it apart! Secondly you don't really have to wait 15 min. before trying to charge it. I have found 5 min works sufficiently. But that's me.

You went through all that trouble to unsolder the cells from the battery management/charger board. And you would have been far better off to "jump" each cell individually (with a voltage and current controlled power supply) which would also give you an indication of each cell condition when you did that. You could have also measured the voltage across each cell without taking them out of the circuit for an indication of charge state. You didn't need to do any of all that just to try a 20V "jump" charge either. HAHA. Safer too, if you had one or two shorted cells putting that 20V on the system (with only 2-3 cells "working") could result in an overcurrent disaster to BOTH battery sets and your test area. Take care, and try that approach next time. -SG

What do I do when the cable that connects to the battery isn't going in when pushed. Should I remove something from it or plug in a specific way, or maybe it needs more force. I'm worried it will break.

I've had so many NEW batteries going bad only in a matter of months. Cheap lithium? No idea what the issue is. Seems like engineered obsolescence to me.
@ronvon86836 ай бұрын
Made the jumpers, hooked the bad battery to the good one, waited 15 minutes, and it worked! The problem battery ( which had been sitting around uncharged way too long) is now taking a charge. Thank you, you saved me from buying another battery.
@GMSEspanol-we2yu6 ай бұрын
An even simpler solution (at least one worth trying first) is pulse charging: Put the battery in the charger and then plug the charger in and out from the outlet a few times for ~5 seconds at a time. I tried it recently and it took about 5 rounds but then it started charging on its own

So is this a version of the 'modern' car battery chargers that will not charge a very low battery, not turning on under those conditions? (I assume a 'save the public' safety feature so the two terminals can't spark or burn up the charger?

another method is to get an adjustable generator and slow charge each battery to around 3.5 volts...and then charge the whole thing up normally

@salvadorelizalde7837 ай бұрын
Gracias amigo, si yo tambien cuando me paso, y si pense que fue porque se bajo demasido la carga y el cargador es muy lento, y es de muy poco amperaje y no alacanza a meterle carga cuando estan tan vacias, asi que necesitan un pulso con una carga muy fuerte para que reviva y el cargador a partir de alli pueda recargarla. Hice lo mismo que tu, con una bateria de 3 amperes solo le di un pulso de 10 segundos y listo cinecte el cargador y con eso fue suficiente para revivirla, saludos...

@StickyWilli8 ай бұрын
Thank you, I took a similar approach. I purchased a cheap (Amazon) variable DC power supply (Kaiweets KP-1010). I just connected the + and - which are labeled on the battery and slowly moved the DC supply towards 18v and no more than 2 amps, for less than 30 seconds. Voila the battery is now charging with a green charging indicator.
@charlino698 ай бұрын
This works for me. Without disconnecting the batteries from the board, I just had to give each of the series a small boost for 10 seconds with another 4.2v battery and it worked.

Seems best not to jump with more than 20 volts. I hooked up two M12 batteries in series and the volt meter read 24 volts. I jumped the Black Decker battery and the wires got extremely hot. Charger is now blinking green. Thanks for sharing.

Additional tip: Tie a knot at the end of the wire so it's on the inner side of that hole. In case you accidentally tug it, it's not gonna rip out the soldered wires :) Thank you friend!!!!!! No more wasting batteries! REDUCE, REUSE, RECYCLE!
