225 minutes at 23 amp hour draw, so about 100 ah per battery, or 50 ah usable.

I bought four of those from Sam's Club branded as Duracell. Great batteries in my opinion, no complaints here.

According to the DATA Sheet
http://www.eastpennmanufacturing.com/wp-content/uploads/Marine-Master-Spec-Sheet-0194.pdf
It's 105 amp hr for 20 so it would only be 210 with 2 Batteries.

"True Deep Cycle" according to local battery dealer. Here's the specs:

Deka DC31DT Marine Deep Cycle Battery (Lead Acid) 12V, 650 CCA

Quote:

Extra cranking power
225min @ 23Amp, 185@25

I bolded the section to ask about.

IF it is true deep cycle, permitting repeated 50% discharge without harm, then two of these would be 440ah vs two GC2 at 205ah.

I *think* this is the model. It matches the verbal info I got from the dealer. I've bought Group 31 batteries from them many times in the past for diesel equipment. But not sure about his deep cycle batteries.

What do you think, what am I missing? [emoticon]
