i have a gas powerd scooter and lost the charger (it needs the electricity because it has lights and a horn) and it wont start wiht out at least a litle charg. If you can start it at all you can use a voltage meter and plug it in where the charger would plug in. That should produce the same voltage and therefor you can read it there. If nothing else you can check the origional battery and read it from there. If it's not listed, you can call the company and ask them {take note of all #'s on the battetry} As a rule of thumb, each cell is 2 volts {so 6 caps =12 volts} I would be happy to answer any Q's cunningly1@yahoo.com |
