OP Back-Just to clarify.
What started this discussion was that I was researching the Sam's Club AGM Gr 31 the simple reason(s), price, availability (I can drive 45min and be at SC, and SC is located in about every town of size where I want to travel to), The SC aka Deka (East Penn) AGM has a good reputation, and 'icing on the cake', East Penn has published info that one can study.
East Penn, on p10 in the 16 Tech Manual shows that @ 50% DOD, one can expect 370 cycles. When I saw that Cabelas/NorthStar was claiming 900 cycles @ 50% DOD, The Engineer in me had to question 'such a large difference in cycle life'.
Plain and simple.
