Looking at their website, it appears they go heavy on alternative types of batteries with silicon dioxide, carbon lead, and carbon foam styles. Literature they give is full of all the same type of misleading hype and calculations which have permeated all battery sales pitches these days.
I could not find anything on charge profiles, especially if they address the very long final top off portion of the absorption stage in AGM charging. Also what is the criteria to judge a full battery, time, volts, amp hours,etc?
They also claim 93% charge efficiency, but don't say if it varies over the charge cycle. The 93% would indicate that they are wasting energy charging like the other lead acid batteries, but they claim the don't heat up, so I don't see how both of those can be correct.
The are heavier by 10% than AGM, so big downside for those with big banks and weight concerns.
Long life claimed, but not yet proven in real life, like all new tech batteries.
Bottom line for me is that it is interesting, but would need a lot more information, I think, as they certainly aren't inexpensive.
