Quick Fix Dewalt Lithium Battery

Показать описание
I've got a Dewalt battery that says it's fully charged, but when I connect it to a USB adapter the power meter shows nothing. I found the electrical terminals inside spread apart over time, and the positive side is prone to damage when it gets too hot. This battery is missing a little prong on the bottom left. So I cut a piece of copper and bend it into a "V" shape. Then slide it into the busted terminal.

Nice!! I use to have this issue with the small 2ah batteries. Does that little piece you added not want to fall out or pull away with the male side when you pull the battery out?

I’m not gonna lie I know this has nothing to do with the video but It would be interesting if you did like a reaction video, you seem like a person who would or maybe like a game review. I don’t know it just came to my mind.
