A G M Batteries
Are A G M Batteries worth the extra money? Do they outlast wetcell Batteries or am I just as well off buying 2 wet cell batteries for use in my 5th wheel? Thanks, Bud99

My RV's two 12V 100 amp hour Interstate (probably made by C&D Technologies for Interstate) AGM true deep cycle wheelchair Group 29 batteries are in their 8th year.
These batteries see the stock ~13.8 volt RV converter most of the time - the RV converter being powered by a 4000 watt Onan built-in RV generator, or a 650 watt portable Honda generator, or shore power. These batteries also of course get hit with the engine alternator hooked up in parallel with the engine's wet cell charging battery via a silver alloy contact solenoid when we're traveling.
These two batteries just sit there, shut up, and do their thing month after month. However I do dust them off about once a year if I don't procrastinate my way out of it. I'll never use wet cell batteries again in our RV. I'd really like to move up to a couple of 12 volt Lithium RV batteries if their prices eventually come down in the common Group 27/29/31 sizes.
