Yuasa 6N4C-1B Conventional 6-Volt Battery

Bring your classic machine back to life with the reliable performance of the 6N4C-1B Conventional 6-Volt Battery. Purpose-built to meet the exacting electrical needs of vintage mopeds, retro scooters, and lightweight motorcycles, this standard flooded lead-acid battery delivers stable voltage output and dependable cranking power. Engineered with specialized thin separators between internal plates, packs maximum energy capacity into a compact footprint so your engine fires quickly every time you drop the kickstart. Built to withstand the unique rigors of vintage riding, the 6N4C-1B features a high-impact casing designed to absorb severe chassis vibration and engine shock. Heavy-duty through-partition connectors create a shorter internal electrical path between cells, effectively reducing resistance to maximize output when you need it most. Complete with specially engineered terminal post seals that resist acid seepage and power-robbing corrosion, this compact 6-volt battery offers the long-lasting performance classic powersports enthusiasts count on to keep original machines running strong.

• Special thin separators allow two extra plates per cell to be installed, for a 30 percent improvement in cranking performance
• Engineered to protect against corrosion, withstand vibration, and deliver high cranking power
