Product details
Power up your ride with the reliable performance of the 12N9-4B-1 Conventional 12-Volt Battery. Built specifically to tackle the demands of classic motorcycles, vintage scooters, and lightweight ATVs, this standard flooded lead-acid battery supplies steady voltage and dependable cranking power to get your engine firing quickly. Engineered with special thin separators between internal plates, it packs maximum capacity into a compact footprint so you get optimum starting strength every time you drop the kickstart or hit the ignition button. Designed to handle tough riding conditions, the 12N9-4B-1 features a high-impact outer casing engineered to resist severe chassis vibration and road shock.
