Battery overheating.what causes?
 

My battery was less than a month old and began bulging.what can cause that?

voltage regulator failed

Yeap...regulator/rectifier is over charging. Just why I installed a volt meter on my scoot.....nice to be able to constantly monitor the electrical system.

Check your battery voltage. If it's more than 14.6 volts while running, your votage regulator is probably bad. I have an in - depth video about it if you want to know more.
