    I used to take those 9-volt battery connectors, wire them up together and then recharge a dead 9-volt with a brand new one until the tester strip thing showed they were both even. Surprised they never popped because they would get really hot lol

      My dad used to recharge alkaline batteries with a special charger, but that was quite useless

          I had a babysitter that used to do that. Even 7-year-old me thought that was a bad idea but she insisted that it was fine.

          I wonder what happened to her. I hope she didn’t accidentally harm a kid in an unintentional D-cell-powered terrorist attack.

          At least that charger had a safety feature that would not charge a battery if it was too worn
