Buying Guide
Choosing the right jet ski battery can seem overwhelming, but here are a few key factors to consider:
- Cranking Amps (CCA): This is the amount of power the battery can deliver for a short period of time to start the engine. Higher CCA is better, especially for larger or older jet skis.
- Voltage: Most jet skis use 12-volt batteries. Make sure the battery you choose is the correct voltage for your jet ski.
- Battery Type:
- Lead-Acid: Traditional and affordable, but require maintenance.
- AGM (Absorbent Glass Mat): Sealed, maintenance-free, and more vibration-resistant.
- Lithium: Lightweight and powerful, but more expensive.
- Size and Fit: Make sure the battery fits properly in your jet ski’s battery compartment. Check the dimensions before you buy.
- Brand Reputation: Stick with reputable brands known for quality and reliability.
- Warranty: A good warranty can give you peace of mind in case of defects.
I always recommend spending a little extra for an AGM battery. The maintenance-free design and increased vibration resistance are worth it, especially for the rough conditions jet skis often face.
