Specifications

Charging and system matching

Recharge the battery after use with an AGM-compatible charging profile and do not exceed the stated 25A maximum charge current. If stored, recharge it periodically; the supplier recommends charging at least every three months to help prevent damaging over-discharge.

The 1,200A figure is a five-second maximum and should not be used as a continuous inverter rating. Confirm continuous battery current, cable size, fuse or breaker protection and appliance surge demand before pairing it with a power inverter. For solar or vehicle charging, compare compatible MPPT controllers and DC–DC chargers.
