I am looking at the golf cart batteries sold at Sam's Club.
I am confused as to why the cheapest battery they sell has a higher 20 amp hour rate than the most expensive one they sell.
http://www.samsclub.com/sams/duracell-golf-car-battery-group-size-gc2/prod3590228.ip?navAction=push#reviews
20 amp hour rate:215
http://www.samsclub.com/sams/duracell-golf-car-battery-group-size-gc12v/prod3870120.ip?navAction=push
20 amp hour rate:155

Does the Group Size mean anything?
BCI Group Size:GC2
vs.
BCI Group Size:GC12

    The 6 V GC-2 is a high volume battery, that has a competitive market, where the 12v is a low volume specialty battery, it's a big battery that won't fit a lot of applications. I am sure their retail price is dependent on their cost, of course this a just a guess.

    Would the ~$85 one be ok for my solar use?

    Yes GC2 s are preferred assuming it is the 215Ahr model.

    While waiting for the page to load there was a bit I managed to read, but don't see it now, it was about limited availability in XX states...??? you may want to follow up on that..

    This is a 12 volt battery

    The cheaper battery will work fine, but understand you will need 2 of them, in series, for a 12 volt system.
    Home system 4000 watt (Evergreen) array standing, with 2 Midnite Classic Lites,  Midnite E-panel, Magnum MS4024, Prosine 1800(now backup) and Exeltech 1100(former backup...lol), 660 ah 24v Forklift battery(now 10 years old). Off grid for 20 years (if I include 8 months on a bicycle).
    - Assorted other systems, pieces and to many panels in the closet to not do more projects.
