Can I charge a rechargable battery by keep put voltage?
it's a long story.
i heard 3.7V Li-Ion rechargable battery has 4.2V at full charged.
but i have a problem with making full charge detect and cutting off charge circuit in my situation.
so i think put 4.1V to the battery all the time makes charging but not over-charging it.
is this possible idea?
thanks in advance.
