I know this is a year old or so, but I've never heard of these and am curious.
Wouldn't the electrolyte being "gelled" be a disadvantage to an AGM? It sounds like it would be mostly just like a gel-cell battery
. The problem with those is if you overcharge them, even a little, bubbles form in the gel and they don't come back, and this capacity is lost
AGMs already have the advantages of gel (temp ranges, non spillable even if broken, etc) without the disadvantages, and can handle a fantastic amount of overcharge etc without suffering too much, so why would these be a good thing?
