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.

if the battery uses an envelope system it is not an AGM battery. They are not constructed that way. An AGM will use a sheet of sacrificial paper for the envelope function. The positive plate is an expanded red oxide lead plate. AGM batteries use two lead plates per cell.

Please pick up your telephone and call Concorde right away. They need to learn they cannot keep manufacturing their Absorbed Glass Mat batteries with envelope separators as soon as possible!

Envelope separators just about eliminate plate to plate mossing shorts and mossing shorts is one of the biggest premature death killers of AGM batteries. Other OEMs are just know incorporating envelope separators for their AGM units. I wouldn't doubt that Fullriver has already made the change. Concorde was first and all Mil-Spec batteries MUST have envelope separators.

Think about it? How are you going to achieve the compression in the cell? The lead plates are stacked on a batting type material. It is very hard to align the plate stack. A sacrificial sheet of paper is used on both sides of the stack during the insertion into the cell. The paper will dissolve once the acid hits it. An AGM battery must remain under pressure to operate. If the AGM battery is using envelopes and printed plates it is not a very good AGM battery. You will be defeating the construction of the AGM, absorbed glass mat design.
