so it has been a few days since i used the op 1 its was fully dead when i started charging it last night
How long does it take to charge from a completely uncharged battery? My unit doesn’t seem to charge after 7 hours!
@HomeLife So it goes into coma when you cut the power supply? Sounds like a dead battery. Have a try to recalibrate the battery meter: Disconnect from power and let it run into coma, but don’t switch it off after the screen goad dark. Connect to charger (a dedicated wall plug with at least 1A current output) and let it charge for at least 6 hours with the power switch still set to on. After that, disconnect and restart.
If that doesn’t help, the battery could be dead and in need to be replaced.
