Mighty Max Battery YTX4L-BS - 12 Volt 3 AH, 50 CCA, Rechargeable Maintenance Free SLA AGM Motorcycle Battery
The Mighty Max YTX4L-BS matches the XSR 125's OEM battery specification exactly, making it a straightforward swap with no bracket modifications needed. Its 12V 3Ah rating and 50 CCA output suit the 125cc single-cylinder engine's modest cranking demands, while the sealed AGM construction eliminates topping up and handles the bike's occasional lay-up periods reasonably well. Caveat: budget AGM batteries like this typically last two to three years rather than the four-plus you'd get from a premium OEM replacement.
