The Yuasa YB12C-A Yumicron 12-Volt Battery (YUAM222CA) is a conventional powersports battery engineered for motorcycles, ATVs, scooters, and snowmobiles that demand dependable cold-cranking power and long-term durability. Built on Yuasa's proven Yumicron technology, this 12-volt, 12 amp-hour battery is a go-to replacement for riders who want a genuine OEM-quality solution without compromise. Whether you're wrenching on a Yamaha or swapping out a tired battery on another powersports machine, the YB12C-A delivers the reliable starting performance you need.

Key Features & Benefits

• Yumicron Extra-Plate Technology: Special thin plate separators allow two extra plates per cell to be installed compared to standard battery designs, packing more active material into the same footprint for superior energy density.
• Up to 30% More Cranking Amps: Delivers up to 30 percent more cranking power than standard flooded batteries — critical for cold-weather starts or high-compression engines that demand every amp they can get.
• Vibration Resistance: Engineered to withstand the vibration inherent in powersports applications, protecting the battery's internal components over the long haul and reducing the risk of premature failure on rough terrain or high-RPM machines.
• Corrosion Protection: Built to protect against corrosion, helping maintain solid terminal connections and extending overall service life compared to lesser-spec batteries.
• High Performance Conventional Design: Classified under Yuasa's High Performance, Conventional battery family — a dry-shipped battery format designed for more recent powersports applications, balancing reliability with ease of activation and storage.
• Trusted Yuasa Quality: Yuasa is one of the most recognized names in powersports batteries globally, and the YB12C-A is a direct result of that engineering heritage — the same manufacturer that supplies OEM batteries to major powersports brands.
