FAQ

Q: Can the battery to be used to start alternator in the car?

No. Please DO NOT use it as a starter battery for any type of vehicle, suchas cars, motorbikes, tractors, etc.

Q: How do I know whether the battery can be applied to start my fuel outboard motor?

Please ensure your fuel outboard motor can meet below conditions when choosing the battery:
1. Please ensure the CCA value that your fuel outboard motor required is < the CCA value(650A) of the battery.

2. Please ensure the output current of the alternator < the max. charging current(80A) from alternator that the battery supports if there is an alternator in the fuel outboard motor.

Q: What's the waterproof rating of the battery?

The battery can support IP67 protection. To avoid potential issues, it is recommended to install the battery in a waterproof battery container and/or position it at a higher level. This will prevent the battery from being partially or wholly submerged in the water accumulated at the bottom of the boat.
