Universal motorcycle battery chargers 12V 4A lead acid battery charger desulfator with LCD

white box, 1*charger, 1*AC cord

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.

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 the charging current is less than 0.5 A, it enters trickle charging state, (at this time percentage bar display as 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 tested every 2H. If the voltage is less than 13V, charger will pulse the battery to recharge.

In additional, the charger can detect battery voltage, percentage while connecting with battery individually.
