UPS Batteries
Are UPS batteries good for use in RV's? (AGM Batteries designed for use in Uninterrupted Power Systems.) What are the advantages and disadvantages? Thanks for your advice.

I have one ESG 6GFM250 8D AGM (250AH) which has specs for "standby" and for "cycle" use. After about a year of RV type cycling like 50-90s it started to act up. It appears to have internal damage to its plates, and operates more like a 125AH battery at two years.
IMO this is more of a "standby" battery, but it doesn't tell you that.
I have had better luck with a pair of 12v 100AH AGMs which claim to be true deep cycle, but also have the specs for "cycle use" and "float use". After three years they are losing capacity quite a bit, so they don't seem to last as long doing my kind of RV work as regular flooded batts despite costing twice as much.
I am going back to Flooded 6s which I know will last me at least 5 years from when I had them before. I do all the good things and moreso for the care and feeding of my batteries, so it was not a case of neglect.
