LED lamp in the 4 v lead-acid battery charging problem!
4 V lead-acid battery discharging termination voltage 3.8 V, charging termination voltage should be around 4.6, the last is constant current charging mode, constant pressure finally, 8 to 10 hours with commonly used charging current (one 8 of the charging current of battery Ann hours). I hope it can help you.
Dedicated charger generally 3 ~ 5 hours, about 200 ma small battery charging current, automatically stops charging. White led lamp voltage 3 v or so, so light is not on the discharge is lower than 3 v
Does not restrict discharging termination voltage, lead-acid battery charging voltage from 4.6 V to 4.8 V. Constant current charging, small floating charge current, constant voltage is usually charge for 10 hours, one night, to artificial electricity stops charging.
