Bests & Worsts Reviews from Amazon

Super light and much smaller than the standard battery -- all good, right. Well on the forth day of riding it burned from the inside out and it was a miracle my bike did not catch fire. Left me stranded and cost me a tow bill to get my bike home. My bike is a 1990, great shape and no electrical issues. Supposedly many older bikes did not regulate charge voltage as accurately as newer bikes. The standard batteries may have better tolerance to handle these voltage differences. For me, I went back to a traditional lead/gel/glass-mat battery at half the cost.
