Sometimes it a rechargeable AA or AAA battery dies and you can’t recharge it. However, it’s not always actually dead, and Iddo Genuth from Lensvid shows you a simple tip how to “bring it back to life.” All you need is another battery and a barbeque clamp.
If the charger doesn’t detect the battery, before you throw it away, try this revival trick. Take any full metal barbeque clamp. You probably already have it at home, but even if not, it costs a few bucks. Clean it thoroughly and make sure it’s dry.
Now, take another battery of the same type as the dead one. Put the negative parts one against the other and make sure they have a good contact. Now hold the positive ends with the clamp, and hold everything together for about 30 seconds. And that’s it, you should be able to charge your battery as usual and use it again.
Iddo warns this may not work with every battery and there’s no precise number of times you can do this before you need to throw the battery away. But he adds that he still didn’t have the case when this didn’t work.
To be honest, this is the first time I’ve heard of this trick, and I’m gonna have to try it. So far, I’ve only been relying on warming the battery up. Do you use this “clamp trick” with your batteries? Do you have any other tricks to share?
