Battery Choice Opinion Please UPDATE
Updated 26 April ---------- Thinking of getting one of these to replace an old pair of wet 6s, where the price here is similar to new 6s. Not sure if it is suitable for RV use doing 50-90s some...

Faster charge/Discharge. Well LIfelines. perhaps. but not the rest
"... Lifelines. perhaps, but not the rest" may not make electro-chemical sense - at least with respect to all AGM batteries having much lower internal resistance than liquid lead acid batteries.
This low internal resistance is most likely the main reason for AGM batteries accepting higher charging currents at any given applied charging voltage.
In fact many AGM batteries have internal resistance values similar to those of Lifeline batteries - some maybe even slightly lower than Lifeline's. Lifeline specifically mentioning their high current acceptance charging does not mean that other competing AGM batteries can't do the same. Other manufacturers just don't seem to make mention of it.
What we need is a comparison of charging current acceptance levels between several mainstram equivalent size AGM battery models under the charging conditions of "constant voltage - unlimited current".
