I have a bunch of UPS units around my house, they all came equipped with AGM instead of Gel cells, life of AGMs in "standby use" is far shorter than Gel cells. Older UPS units which came with Gelcells battery life was 5-6 yrs, the newer units equipped with AGMs I end up changing out 2-3 yrs..
Gets downright expensive after a while replacing AGMs.. So much so, have considered dumping the standalone UPS units, adding a dedicated Triplite APS series inverter/charger and yes, a pair of 6V FLA GC2s.. I can setup the GC2s/inverter/charger in a separate garage where my whole house gen lives and run inverter only power back to a couple of dedicated outlets.. Instead of needing to replace $60-$100 worth of AGMs every 2-3 yrs I would now have 10+ yrs of battery life.
Call me cheap, but dang those little wimpy AGMs hurt the wallet.
SiO2 are pretty much the same price as AGM's and ought to last a lot longer.
