The lead-acid battery charger is adopted a three-step charging: Constant current--Constant voltage-floating charging). It can protect and extend the battery life when the battery form a float-protection after the light switching. Besides, it also has other advantages:Over-current protection, Short-Curcuit protection, Reverse protection, LED indicator charging and full-charging indicator.
General Features
Over-voltage protection, over-current protection, reverse connection protection, full automatic charge.
