Mini 2 battery not charging

[Frosty Of The North]

The terminal damage might be the problem. The battery might not be seating properly. You might be able to use a small piece of stiff plastic to fix/straighten them up and then take care every time you put it into the drone or the charger.

By now this battery doesn't owe me anything. I've gotten my use out of it. I'd rather have full confidence in a battery being 100% intact than mess with terminals. The cost of replacing the battery is much less than the potential cost of something going wrong.
