I'm have a challenge with the battery replacement for an R1. I purchased a Duraboost brand CTZ10S battery from Cycle Gear. The battery consistently measures 13 - 14+ volts when fully charged yet still struggles to turn the engine over. Specifications advertise CCA's of 130. The Yuasa brand YTZ10s advertises 190 CCA's. Could the brand or the CCA's be the reason for the poor performance of the battery?

FYI, to help all interested:

I replaced Duraboost brand CTZ10S battery from Cycle Gear with Yuasa YTZ10S from Cycle gear. Yuasa performs reliably from installation without recharging. If the Yuasa doesn't have 190 CCA's It definitely has more than the Duraboost. My advice is only replace with a 190 CCA battery. YUASA YTZ10S works better.
