Attentions
Over charge protection and short circuit protection 5-in-1 charger adapted to charge 5 batteries at the same time.This charger has a power management IC and the protection voltage is 4.0V±0.1V.Normally, the led light will turn off when the voltage is over 4.0v.If the led light starts flashing, it means that the battery is close to fully charged and the voltage is around 4.0v.This phenomenon often occurs to nearly fully charged batteries, exhausted batteries will not have this problem.
If a power supply being used supplies less than 2 amps, it is normal for some of the LED indicators to be off or flashing due to the low supplied current level. To solve the problem, the number of batteries being charged must be reduced to 3 or less.If charging more than 3 batteries, the power supply must be able to supply an output current of 2A or greater.
