About this battery

This is a direct replacement for the YTX20L-BS: the same voltage, polarity and battery case. It leaves the factory with the electrolyte inside and charged, so there is no acid pack to fit or waiting around: check the voltage and fit the battery.

Use a smart motorcycle battery charger, with a recommended charge current of about 1.8 A (capacity divided by 10) and never more than 3 A.
