This compact, rechargeable battery is built for motorcycles and small powersports vehicles that need dependable cold-start performance and a durable, vibration-resistant power source.

A full one-year warranty backs the battery for peace of mind.

How much starting power does the YT12B-4 provide?

The YT12B-4 supplies 125 cold cranking amps (CCA), which helps ensure quick engine starts in cooler conditions and under moderate loads. Because CCA measures the battery's ability to deliver a strong burst of current for starting, this spec is useful when comparing starting performance between batteries.

• 125 CCA for dependable cold starts
• 12 volts nominal output suitable for most motorcycles
• 10 amp-hours (AH) capacity for standby and accessory use

Is this battery safe to install and maintain?

Yes — the AGM/SLA construction is sealed and spill-proof, so there’s no need to add water or handle liquid acid. The battery resists shocks and vibration, and can be mounted in various orientations, simplifying fitment in tight or angled battery compartments.
