| Battery charger starting behave weird so reversing polarity |
| (1/1) |
| marhuum:
This'd be a discussion only now, not repair technicality A cheap low quality, standalone 4.4 V Li-ion battery charger for light torch is starting to get old. It's made for 2 loads in parallel In the past 4 months it behaves weird, the polarity suddenly get reversed while every other thing is functioning normally! So simply reverse the load, ie. battery, polarity which simply works charging them till full. But on other time before being full while charging in reverse, it gets back to normal, ie. original, polarity. So if not checked for too long beyond the usual full charge time limit, the charge result just getting back to reduce the battery voltages! So one expert or kind enough to shed lights on it for all of us ? |

It could be as simple as the hamsters in the charger got tired of running in the same direction. But it more sounds like quantum computing to me. Where what and how did you measure those voltages? |
