Well we're down here in Quartzsite again and one of the solar places has the new Interstate Pro ECL batteries. They're selling them as a gp24/100ah deep cycle battery for a fairly good price. I've che...

Amp hour ratings can be deceptive. For example if you go to Wal*mart and check out the specs on their Group 24s they will say something like 110 amp ahours at the ONE AMP rate"
We prefer to use the C/20 (20 hour) rate, and a G-24 is about 75 amp hours give or take a couple for all battery types save OPTIMA, (Optima it is closer to 50).
Make does not matter, (Except as noted) the amp hours per pound is a constant for all six volt, or for all 12 volt batteries and though you can put less lead in a group 24 package (Evidence Optima) you can not put more in.
(pound for pound six volt have 2 times the amp hours, but you need two of them in series to make one 12 volt and this makes it so the constant is the same for all 12 volt batteries, INCLUDING those made up from 2 six volt, If you find this paragraph confusing, ignore it).
Eventually they will come out with other chemistry batteries. Example: Li-ON, some of these may give a different amp-hours per pound rating.
