My battery is 4 years old and I load tested it today and it is between good and weak. I have a 2014, 17 kw Honeywell, Model 0062820, serial 9142***.
Will this generator be able to charge a AGM battery ?

I certainly don’t consider myself an expert on the matter but I’m not aware of AGM batteries having different charging requirements. As far as I know the only real difference in AGM (absorptive glass matting) is that the plates are wrapped in fiberglass mats that keep the electrolyte distributed evenly on the plates and keep the liquid from sloshing around so much. I welcome additional input on this.

your agm battery will be fine with the onboard charger of your generator.

The electrolyte in an AGM battery does not "slosh" around at all.

I meant as compared to a traditional wet cell battery.

There is no free liquid in an AGM battery. It's all absorbed in the glass mat.
Probably where they got the name. ;-)

You can even mount them on their side or upside down.

My 10kw with Nexus controller/charger has been running just fine with a AGM battery for almost 3 years now.

Technically only the Evolution controller has a charging profile suitable for an AGM battery, The Nexis controller does not, though I am sure they will work but not to the manufacturers specs.

Good to know!

So that's a maybe yes or maybe no, right ?

it's a definite yes.
agm's have been running for at least 3 decades on regular lead acid charging protocols with no ill effects.
