G100-12A 12V Lead Acid Car Battery Charger with Battery Meter
G100-12A is a main member of digital-chargers from Green Digital Power-tech Co., Ltd. It represents today's new technology for lead-acid type battery charging. G100-12A programmed four auto stages (Ud-Im-Uo-Up) charging process,It is designed for all kinds of 12V lead-acid battery, 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.

How to use:
1. Connect the AC cord to the socket, The "power" lamp will light on solid.
2. Connect positive charger clip (red) to positive battery terminal, the black clip to negative. (You can use other dc plugs to connect battery), the "25%~100%" lamps will light on flowing. If the battery polarity reversed or output shorted, all lamps will flashing, please check the setup.
3. Depend on the charged capacity, 25%~100% lamps will lights up solid sequence, until the battery is fully charged. Then you can power off the charger and disconnect the battery or you can charge a new battery if you need.
The table shows the duration of 80% state charged for an empty battery.
