This is a direct replacement for the YTZ14S: the same voltage, polarity and case size. It leaves the factory with the electrolyte inside and charged, so there is no acid pack and no waiting: check the voltage and fit it.
It delivers 12 Ah at the 10-hour rate, compared with 11.2 Ah for the original battery code, giving you more starting power and reserve when the motorcycle is parked.
Use a smart motorcycle battery charger. The recommended charge current is about 1.2 A (capacity divided by 10), and should never exceed 3 A.
