Missunderstanding my statement

I stated that the AGM batteries are not designed for anythhing with wheels is somewhat explained in the long text.

The normal place for AGM/VRLA batteries are stationary service in a fixed location with climate control, usually about 72 to 77 degrees F, charging voltage fixed at 2.25 Volts Per Cell, discharges kept shallow if possible, and loading based on 8 hour discharge time.

They also were not intended to be in high viberation environments.

They will do very well in that environment, but they were NOT designed for it, and will not last their intended duration when used that way,

A past employer had a full market replacement of more than 900 units due to poor design that would later fail if they were bumped too hard during transportation or install, quite a few blew up after a year or two.

All of that being stated, the better quality units may actually hold up better than a flooded battery due to the glass mat design and a few other details, however, given two sets of identical battery sets, the ones exposed to the back country with heat ind viberation will certianly be degraded compared to the set used as intended.

The flooded batteries will have spilled some acid and also may fracture internally.
