Battery AH size

[Tacouser]

I have 2017 Class C 31W. What is the AH rating of the factory installed Harris batteries?

Should be a label on the top of the battery that shows that information.

If it's a 27: it should be about 100 AH

However if they were treated like mine by the dealer they may be shot. As measured by a discharge to 12V with about a 10 amp load mine had a useful capacity of under 10 Ahr for the pair!

I was speaking theoretically...

My OEM batteries were also the Cheap "Harris" Batteries. They were Black in color and Unmarked. I remember looking them up and they were only like 80 amp hours each max. Only lasted me 6 mo and nobody would stand behind them.

So I replaced them with Two 6 volt AGM rated at 220 each (so really 110 in 12 volt). One of the best Mods I have done. AGM's are great.
