So lately I get the one solid light one flashing, even when a battery is reading 4.2v in both my sid and through my multimeter. I have yet to see the three indicators lately, resorting to guessing if the battery is indeed charged. The charger is two months old and I use newish vtc5s. Could it possibly be overcharging, or perhaps just trickle charging? I have had some free time lately guess I never really watched it charge, could just be paranoid.
