Built for Off-Road Abuse
Off-road vehicles put far more stress on batteries than most street vehicles. Rough terrain, vibration, heat, winches, lighting, audio systems, and cold starts all add up quickly.
The FAYIX30L is built with:
- Enhanced active material to resist vibration damage
- Protective separator material for added durability
- Heat-bonded construction to reduce flex and leaks
- High-impact case design for rough riding conditions
Strong Starting Power for RZR Builds
With 385 cold cranking amps and a 30Ah rating, this Interstate AGM battery delivers dependable starting performance for stock and accessory-equipped machines.
It’s especially useful for riders running:
- Aftermarket audio systems
- Light bars and chase lights
- Communication radios
- Winches
- GPS and navigation systems
Add a TrueAm Battery Isolator
For riders running multiple accessories, adding the TrueAm Battery Isolator (UTV-SBI-CM) is a smart upgrade. A battery isolator helps separate accessory power draw from your starting battery, reducing the risk of draining your main battery while parked or using electronics.
It’s a popular upgrade for RZR owners with larger electrical systems or audio builds.
