Onan makes many generators SOME do in face recharge the battery but the ones marked RV do not. What they do is power the hose SAME exactly as if you were on shore power so the converter recharges the battery..... I might add it also provides power to the Onan's fuel pump. The rest of the Onan is self powered.


Home is where I park it.

If I'm on shore power, I also have my city water connection hooked up so it doesn't make sense for the generator to power the hose.

And that folks is why we need more mental health care facilities.

I think it’s better for the converter to charge your batteries because if the generator has away to charge they will usually over charge your battery if you run them a long time.

No, it only supplies power to "start" the generator.

Something I have never understood about generators (I have an Onan 6.5 Emerald III.) A 12-volt DC battery is used to start the generator, which then produces 120V AC. The battery supplies the energy needed to run the generator, right? So, while the generator is running, does it send a 12-volt DC current back to the battery to keep it charged, or does the generator just continue to drain the battery until the battery no longer has enough voltage to keep it running?

So if the generator drains the battery, then there must be a converter in the circuit to keep the battery charged, just like the alternator on a car engine. OK, I'm no electrical engineer, I just want to be sure that I understand this correctly.

Thanks for your tolerance on this post.
Put your meter on the battery terminals. 13.6+ volts and you are charging. 12.5 volts or less and you are not charging. Post your measurement and you will be an honorary electrical engineer.
