G100-XXA is a main member of digital-chargers from Green Digital Power-tech Co., Ltd. It represents today's new technology for lead-acid Battery charging. G100-XXA programmed four auto stages ( Ud-Im-Uo-Up) Charging process, It is designed for all kinds of 12V~36V lead-acid battery pack, Such as SLA, AGM and Gel battery. Stage "Ud" desulfurating the battery Through 18V pulse (for 12V battery), When the battery recovered, stage "Im" Will give bulk current charging. Then, "Uo" stage is followed, the output voltage Is limited on 14.7V( for 12V battery); When the battery is nearly full, stage"Up" Will turn on duty. At this stage, the battery is charged completely and the Charger give some pulse to maintenance the battery.

Further, G100 can display the charging process, indicate the battery Capacity from 25% to 100% timely. This is helpful for user.

For more safety, G100 will inter protection mode when the battery polarity Reversed or the output connectors shorted.
