About this battery

This is a direct replacement for the YTX4L-BS: the same voltage, polarity and case size as that battery part number. It comes from the factory filled with electrolyte and charged, so there is no acid pack and no waiting: check the voltage and fit it.

It delivers 4 Ah at the 10-hour rate, more than the 3 Ah of the original battery part number, giving you more reserve for starting and when the motorcycle is parked.

Use a smart charger for a motorcycle battery. The recommended charge current is around 0.4 A (capacity divided by 10), and never more than 3 A.
