NAPA Commercial 12v Battery ( Amp Hour? )
My MH came with two of the NAPA Commercial 12v batteries (part#7236) as my coach bank. I read people chatting about having 220amphour, ect. I don't see that rating on this battery. Is there a formula ...

130 amp hours each is my guesss. the key spec was the #31
A group 31 battery is about 130 amp hours.
HOWEVER: From the ratings I'm guessing a Marine Deep cycle
Thus two are 160 AMp hours but you can't use all that, IN fact you can't even use 130 of it, only about 100 amp hours are usable after that damage sets in on the batteries.. So the GC-2, where you can safely use HALF the battery, (It is a DEEP CYCLE not a MARINE/deep cycle) is a better choice.. Or better yet, upgrade to 2 pair of GC-2
Each pair wired in series to get 12 volt, is treated exactly as a SINGLE 12 volt battery.
