Buying Guide: Key Considerations When Choosing a Jet Ski Battery
- Battery type: AGM/SLAs offer maintenance-free operation and spill protection. Lithium options provide weight reduction and longer life but require compatible charging systems.
- Cold-cranking amps (CCA): Higher CCA improves starting performance in cold weather. Match CCA to your engine’s needs and local climate.
- Battery size and terminals: Confirm tray dimensions and terminal orientation (left negative, right positive, or other configurations) before purchase.
- Maintenance and warranty: Consider whether mounting hardware is included and whether a warranty covers your region.
- Weight: Lithium options can significantly reduce overall weight, which can impact handling and fuel efficiency in some setups.
- Charger compatibility: Ensure your charger supports lithium or AGM chemistries if you switch chemistries.
