Mighty Max Battery YTX9-BS 12V, 8Ah, Replacement Battery Compatible with Kawasaki 300 Versys-X, ABS KLE300C 24
The Mighty Max YTX9-BS matches the Versys-X 300's factory battery spec exactly — 12V, 8Ah — so it drops straight into the OEM tray without modifications or adapter brackets. The sealed AGM construction handles the vibration common on adventure-style riding, and it's listed as a direct replacement for the KLE300C. Pricing is noticeably lower than dealer alternatives. Caveat: some riders report capacity degrading faster in cold climates, so if you're riding year-round in freezing temperatures, consider a higher-tier AGM brand.
