Rechargeable Battery Level #13

Closed videodj closed 5 years ago

I have tried 2 sets of fully charged batteries and they only show as medium. When I switch to some Duracell batteries they show as full. Does it detect battery level differently for rechargeable batteries?

Hey, the program itself doesn't detect the battery level, it just displays what the controller reports. My guess would be that level detection is done via voltage levels since most batteries slowly drop in voltage as their charge goes down. Normal AA/AAA batteries have a regular voltage of 1.5V while rechargeables usually have "only" 1.2V. So that is probably why it only reports medium even though they are fully charged, because the start voltage is lower.
