What could be causing my scooter battery to overcharge and overheat?

by Lisa
(Phoenix, AZ)

When I ride my Zhen King Kong 150cc scooter for more than a half an hour, the battery overheats. When I turn the bike off, there is a hissing noise for about 20 minutes. Then the battery will die.

I have had to replace my battery 3 times. Any idea what is causing the battery to overheat? Something is overcharging the battery but what is it?

P.S. I am riding in 75 degree weather, not overly hot days.

Voltage regulator
by: Anonymous

All electrical power for your scooter comes from the generator. the output of the generator goes to the voltage rectifier/regulator.

The rectifier/regulator controls the voltage going to the battery. Too high voltage will cause the symptoms you describe. Replace your rectifier/regulator.

Battery Tender Junior in package

A battery tender like the Battery Tender Jr. can make all the difference in whether your scooter will start right up each spring, after being stored for months.

Just about every scooter owner needs to have a battery tender, sometimes called a trickle charger. Unless you are lucky enough to live in a climate where you can ride all year long, chances are your scooter will be put on ice, figuratively-speaking, for at least a couple months every winter.

One of the key steps in winterizing a scooter is to protect your battery from draining during its "rest" period. This can – and will – happen if you leave your battery sitting untended in your cold scooter over the winter, even if it's in a garage or shed.

Chances are, there is a good reason. Did you...
