Back up generator battery charger

I own a DuroStar DS10000EH 10,000 Watt Hybrid Dual Fuel Generator with electric or pull start. I have one question.

When this generator is running and the generator is pumping out electricity does it recharge the battery?

Or, do I need to set it up with a trickle charger to keep the battery charged for the electric start option?

My first thought is yes.

It is NOT on an automatic start up schedule.

Needless to say the paperwork that comes with it is less than helpful.

Thanks in advance.

It should charge the battery when the engine is running. Every electric start machine with a battery I've ever used has.

They don't actually come out and say that the on-board battery gets charged but it is wired that way in the wiring diagram.

Smile great!!

So if I run this generator on a certain schedule say once every other week for 15-20 minutes I should have no issues with a dead generator battery.

That is great!

And no, the paperwork that comes with the generator does not explain much, especially something this important!


Thanks again for any and all input given thus far and thereafter!

If you don't use the generator often, it might be more economical to just keep it winterized and keep the battery charged with a float charger.
Some generators come with one.

Since there is no drain on the battery until the generator is started, I'd say running generator once a month or two is enough to keep the battery charged.
Lead acid batteries should be topped off every 6 months. But that it would like longer to fully charge at that interval.

Thank you for the addition information and options. My feelings are that at least once a month I should give it about 30 minutes of run time. I installed this generator in a plastic barrel shed and then vented the shed and installed an exhaust fan to vent the shed. There is another intake vent on the other end of the barrel shed. With the fan running off of the generator there is some 'draw' on the generator.

I was going to set up the float trickle charger I used on my boat to do just what you did, initially but felt that I want to run the generator on a schedule of some sort. If that keeps the battery at it's proper voltage I should be good to go. We shall see!
