Frequently Asked Questions

Is this battery suitable for jet skis?

Yes. The featured 12.8V 30Ah 400CCA configuration is designed for compatible personal watercraft and compact marine engine starting applications.

Can it be used for a fishing boat?

Yes, when the battery voltage, CCA, dimensions, terminals and charging system match the fishing boat engine requirements.

Is this a trolling motor battery?

No. This product is primarily designed for engine cranking. Trolling motors require a separately selected deep-cycle propulsion battery.

Is 400CCA suitable for every marine engine?

No. Required cranking current depends on engine displacement, engine design, operating temperature and the original battery specification.

Does the battery support Bluetooth monitoring?

Bluetooth monitoring can be supplied as an optional configuration according to the selected BMS and project requirements.

What information is required for battery selection?

Please provide the watercraft model, engine specification, original battery voltage, capacity, CCA, dimensions, terminal position and charging-system voltage.
