Kawasaki S1 Series Battery Replacement (1973-1975) - Motobatt MB5.5U AGM
Kawasaki S1 Series Battery Replacement (1973-1975) - Motobatt MB5.5U AGM
Warranty
Set Up for the First Start of the Season
Look at the S1's leads before that first start, too. A loose or crusted lead can make a healthy battery act weak, so seat each one clean and snug on its post.
- Four posts, red and black capped on top - connect each S1 lead plus to plus and minus to minus.
- Hex key, terminal brackets and screws - in the box, for the pair of posts you use.

Frequently Asked Questions
Before the first ride of spring, what do I check on the battery?
Start with its voltage. If it reads low, charge it fully, let it rest off the charger and read it again. A battery that drops back low can no longer hold a charge, and it's time for the MB5.5U.
Should I charge the MB5.5U before the season starts?
Not a new one going straight into the S1. It comes activated, and the label on the case says it needs no initial charging. If it spent the winter in the bike or on a shelf, meter it first, and a low reading means it goes on the charger.
Does this battery also fit a 1976 S1?
Yes. Our Kawasaki S1 Series Battery Replacement (1976) listing carries the same MB5.5U, so order from the page that matches your model year.
Tell us the model year and the battery code off the old label, and we'll match both to the MB5.5U before you buy.
