I'd be grateful for some help. I bought a 4Sevens single bay Li-ion charger recently for my (2) Eagletac 3100mAh batteries. Works fine, but I notice they come off the charger at 4.12V. Changed DMM battery, and bought another DMM. Still 4.12. I know (from reading here) that this isn't a bad thing, and will expend the life of the batteries. The voltage stays at 4.12 after a few hours.
I just got a MP1 charger as part of a Xtar light set, and it charged the Xtar battery to 4.22V. Same with one of the Eagletacs.
Question is, which charger would you use given these two options?
