YTZ12S vs. YTZ14S
Did you know that both of these batteries are of the same physical size? There are two distinct but minor differences--Cold Cranking Amps and Amp Hour Capacity. The TZ14S has 11.2 amps instead of 11 amps and 220 CCA instead of 200 CCA. That 10% difference in CCA means you should be able to use these batteries interchangeably. You can definitely use the 14S in place of the 12S! In fact, Moto Classic figured it out and combined the two part numbers into one battery, the YTZ14/12S.
