Replace your YTZ10 with this HJTZ14 Li-Ion battery and never worry about running out of juice again! 290 CCA and unparralel performance. We have been using these batteries on our personal bikes since 2008 and they are still going strong! The battery comes with a digital tester to see the power level (High, Med, Low). With a weight of just a mere kilogram it’s one of the lightest batteries around in its class.
