Common Scooter Battery Sizes

I have tried to assure this information is accurate, but double check to be sure and from the scooter service manuals.

Batteries differ in voltage, amperage, size and orientation of the terminals and vent location. Sometimes you can get away with a slightly bigger or smaller size or a different orientation. Also in some cases sealed batteries can be substituted for conventional batteries. They are more expensive, but there is zero maintenance and you don't have to fool around with routing the vent tube (because there isn't one).

I'll be adding a section on battery maintenance soon. To get you started, check out the Maintenace/FAQ's section on the Yuasa web site.
