Lifeline offers 2 different group 31 batteries
The GPL-31T is 105Ah
The GPL-31XT is 125AH
They also make on in the t-1275/ scrubber category which is s slightly enlarged footprint but an inch or 2 taller.
The GPL-30HT is 150AH and its increased weight/ capacity and only slightly inflated CCA ratings, could lead one to believe its plates are even thicker than the gpl-31XT
Most carbon foam AGM info can be found on marine forums. I will be waiting eagerly for more info from poster Maine Sail on cruisers forum or poster CMS ( same marine technician) on trawlers forum about them. I don't expect to be battery shopping for another year, or 2.
Mainesail does perform 20 hour capacity tests with all the special equipment to maintain temperature and amperage as voltage drops. He says the failure rate when a battery tests below 80% capacity skyrockets, and only foolish blue water sailors leave port with batteries testing at 80% or under.
