FAQs

What size battery does my ATV need?

The right ATV replacement battery matches your machine's group size and the correct voltage. Most ATVs use a 12-volt powersport starter battery, and our Full Throttle and FTS Series list every group size each model fits, including common BTX and BTZ sizes. Read the group size off your original battery or use our Battery Finder to match an ATV battery to your quad, side-by-side, or utility vehicle.

Are AGM batteries good for ATVs?

Yes. An AGM battery is an excellent choice for an ATV. Our absorbent glass mat (AGM) design is sealed, spill-proof, and maintenance-free, with strong vibration resistance for tough terrain. Compared to a conventional battery or a flooded lead-acid battery, an AGM battery delivers more reliable performance and longer battery life. Some riders consider a lithium battery or lithium powersport batteries, but Fullriver focuses on premium AGM that provides dependable starting power without a special charger.

How do I charge and maintain my ATV battery?

To get the most battery life from your ATV battery, recharge it with a quality battery charger after each ride and keep it topped off during storage. We recommend a multi-stage AGM charger or battery maintainer over a basic battery tender or trickle charger, since a proper charging system fully restores capacity. After a ride, disconnect the battery so your ATV's electrical system does not slowly drain it.

Will a Fullriver battery fit a Chinese-made ATV?

In many cases, yes. A lot of imported and Chinese ATV models use common 12-volt powersport group sizes, so there is often a Full Throttle ATV battery that fits as a direct replacement. If you need a Chinese ATV battery replacement, check the group size on your existing battery, then use our Battery Finder or contact a dealer to confirm the correct fit for your quad, dirt bike, or four-wheeler.

How do ATV batteries perform in cold weather?

Cold weather is hard on every battery, but a sealed AGM battery handles it well. Our high-performance AGM batteries deliver strong cranking power in winter and stand up to extreme conditions and rough terrain. In very cold climates, keep the battery fully charged, and some riders add a battery blanket to retain warmth. A well-maintained AGM battery rewards you with reliable starts and consistent performance season after season.
