during the charging process is one of the times when the batteries are at the most risk of having issues ,please dont go out while they are charging ,its just not good practice ,if you have not seen what happens when things go wrong, just look at some vids on the subject, and you will not leave them unattended againIf you leave charger on battery and left the house for a few hours is this bad?
Does it charge and then stop? thank you
if you were asleep while they were charging ,then that unattended as wellYes the chargers will stop charging when battery level is full.
They do suggest that you do not charge them unattended.
I have charged mine overnight with no problems. Keep an eye on the battery and make sure there is no bloating or that the battery gets hot.
