Right, one of the three I considered was said to be able to survive the heat of a main battle tank (the producer would know since it is a supplier).
When I looked into this a few months ago, it was clear that AGM is the way to go for all sorts of reasons even though where I live nothing will last long. I was told that it may or may not be able to make its 4 year free replacement warranty. I would not mind a brand new free one in 3.5 years!
