Amp hours at the 100 hour rate. Difficult to find data because cheapo battery manufacturers consider this "Extraordinarily Privileged Information". Gee I wonder why? This is where the Lifeline hoses AGM competition.
High density acid skews the picture with flooded batteries. Chew and spit 1.400 acid characteristics would turn car jar cyclable batteries into real powerhouses. Complete with a ninety-day warranty. Look for it...
