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

posted by Josey on 04/18/2007

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

Pros:
Great concept on paper. Versatile charger.
Cons:
Finish charge voltage of 4.25 volts or more should not be considered acceptable.
Other:
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.
Bottomline:
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.
