Brief Introduction
GA6012 is a new member of a family of professional charger in our
company. It represents today’s new technology for lead-acid type battery
charging. Programmed four auto stages (
Pre-charge, repair or normal
charge-trickle-pulse maintenance
) charging process
，
It is designed for all
kinds of 12V 4~100Ah lead-acid battery, such as SLA, AGM and Gel battery.
Charging instructions
：
Connect battery to detect voltage firstly. When battery voltage is less
than 11V, it enters pre-charge mode. Half an hour later, if the voltage is still
below 11V, it enters the repair mode(Repair). (Repair time is 24H, if 24H later
the battery voltage is still less than 11V, It is recommended to replace the
battery, if it is higher than 11V, enter the main charging mode); When
charging current is less than 0.5 A, it enters trickle, (at this time percentage
bar display 100 %, and charge full(FUL) display). When trickle current is less
than 200mA, charger will cutoff completely. After charging cut off, the
battery voltage is detected every 2H. If the voltage is less than 13V, charger
will pulse the batte
ry to recharge.
