Onan generator question

Recommended Posts

Hello, I was wondering what battery i should use to start my Onan 3.5kva Genny? At present i am using a small car battery, but it keeps going flat. The ammeter is reading 8+ amps when running. Now i assume this is the ammeter for battey charging? But i may be wrong.

Hi there, the ammeter by the start stop switch shows the current being put in to the battery. they recommend at least a 100 Amp / hour battery, also it will take a while to put back into the battery what you took out starting it.
