I think I was first one on the site to get a Shorai battery, coming up on 12 months now. Nothing new to report, battery is cranking as fast today as it was a year ago. Cold started at an OAT of 38 F the other morning and cranked my CBR very fast. ZX-10R has the original Yuasa lead-acid and barely cranked at the same temperature, sounded like it was struggling and it's only 6 months old.
If this battery will last one more year I will count it a complete success, Shorai says it will last five years minimum, we shall see.
