Shouldn't it be (delta >> >= 5), that means "turn off charging if the voltage >> went down at least by 0.005" Volts?

NLe> No, it stops if the voltage drops quickly, a negative-delta detection. But 0.3 Volts dropping (see powermgm.c comment)? That is not the voltage drop that marks a complete charging. Thats too much! I thought that the 0.3 Volts is the value that stops charging when the battery voltage goes UP (it wouldn't normally). | now a little more ascii art ;) | | +0.3v _----_ -0.005v | _-/ \- | _/ | _---/ | ___-------------/ |---/ ------------------------------------------------ Bye, Uwe.
