YTX14-BS Lithium Motorcycle Battery, ATV Battery 12V 8AH 600CCA Compatible with Yamaha Scooter Snowmobile Jet Ski, Scooter, PWC & More
The YTX14-BS is a solid match for the Yamaha FZ25 because its 12V/8AH rating aligns with the bike's electrical demands, and the 600CCA lithium output delivers reliable cold starts without the weight penalty of a conventional lead-acid unit. The standard YTX14-BS footprint fits the FZ25's battery compartment without modification. Honest caveat: lithium batteries can be sensitive to deep discharge, so avoid leaving the bike unused for extended periods without a maintainer.
