Battery Trojan vs. LIfeline
Ok, i've done my research, measured my area for a 2-battery bank and am looking at these two possibilities: 1) Lifeline - GPL-6CT RV - 2 6-volt AGM batteries - $440.99 + s/h - Total = $1,023.94 ...

I dunno. I sort of like the THOUSAND AMPS overkill for inverter high loading and being able to charge the battery in half the time. The AGM also tolerates 80% discharges a lot better than flooded.
Make up a list of plus and minus features.
When the B2 bomber starts using Trojan AGM then I will feel they are competitive with Concorde's Lifeline. Call Trojan and ask them specs for thickness of positive plates. The Lifeline has .090" plates. And envelope separators. If Concorde gets some serious competition their retail price will drop.
Is battery weight per amp hour any indicator of quality or longevity in AGM batteries? I've heard it is in other types.
Was looking at Group 31 AGMs and was surprised to see that Lifeline has the lowest #/Ah:
Lifeline, GPL-31XT, 74#, 125Ah, 0.592#/Ah
Lifeline, GPL-31T, 64#, 105Ah, 0.610#/Ah
FullRiver, 115-12, 72#, 115Ah, 0.626#/Ah
East Penn Deka, 31M, 69#, 105Ah, 0.657#/Ah
(also Duracell Total or Sam's Club)
Exide Nautilus, XMC-31, 71#, 100Ah, 0.710#/Ah
(Also Canadian Tire Nautilus Ultra)
Lifeline and FullRiver seem to be packing more Ah into their batteries for a given weight.
Better technology, or lighter (cheaper?) plates, or ...?
