12V 3.3A motorcycle/auto lead acid charger

this charger is a new member of a family of professional chargers from GUDY. It represents today’s new technology for lead-acid type battery charging. 3PA5015R programmed four auto stages ( Ud-I-Uo-Up) charging process，It is designed for all kinds of 12V 2~90Ah lead-acid battery, such as SLA, AGM and Gel battery.  Stage “Ud”  desulfurating the battery through 20V pulse，When the battery recovered, stage “I” will give bulk current charging( 0.8A or 3.3A, defined by user, for 2~8Ah 0.8A is prefer, 12~90Ah should select 3.3A). Then, “Uo” stage is followed, the output voltage is fixed on 14.4V(  14.7V is for low temperature, <5℃）； When the current declined to 0.4A；stage”Up” will turn on duty.  At this stage, the battery is charged completely and the charger give some pulse to maintenance the battery.
