Great on paper but high voltage is concern – UltraFire 3.6/3.7V Battery Charger Reviews

Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

Great concept on paper. Versatile charger.
Finish charge voltage of 4.25 volts or more should not be considered acceptable.
My particular charger has a finish voltage of 4.31 volts on unprotected 18650 cells. Both cells are exactly 4.31 volts so the charge per bay is very consistent, but WAY TO HIGH.
If the manufacturer corrects the overcharge problem with this charger, this would be a GREAT charger. Based on others experience with overcharge I would not recommend this charger unless there was a guarantee that this problem has been corrected.
