At DMG Motorsports, we present the Fire Power CT4B-5 Sealed Factory Activated Battery — a compact, ready-to-run power source built to get your dirt bike or scooter starting strong every time. Backed by decades of powersports engineering experience, this battery ships filled and pre-charged straight from the factory, so there's no messy acid-filling or lengthy initial charging required before you hit the trail or the street. Whether you're refreshing an aging OEM battery or building out a fresh project bike, the CT4B-5 delivers dependable, low-maintenance power in a small, lightweight package.

Engineered with advanced absorbed glass mat (AGM) internals, this battery is designed to outlast and outperform traditional flooded lead-acid batteries in durability and cranking consistency. Because it's fully sealed, there's no need to check fluid levels or top off acid — just install and ride. DMG Motorsports backs this battery with the manufacturer's standard warranty for extra peace of mind on your purchase.
