I thought I would get a couple opinions on which way I should go for my Battery replacement strategy this time. A little background:I just replaced my converter with a Progressive Dynamics Inteli-Power Converter 9200-14.8 Volt Deck Mount.I had a pair of Costco GC2 Battts that were put into service on 2/2013, but were abused by my crappy WFCO converter. When I boondock, I always run my Honda 2000 (with 5 gal. external tank) basically 24/7 while I'm at the Dunes, and if not out in the sand I have power available at my covered parking. Trailer is always in the higher temps of west coast (Las Vegas, Desert)Just recently one of my GC2s developed a shorted cell, so I need to either replace those with new 6V, or possibly with a single 12v AGM. Since I never really run my inverter or 12v for any length of time without plugging in what would be the the most economical, trouble free, dependable way to go?Thanks in advance!!!!!!!Costco GC2 batts are $86.00ea so a pair would be about $187.00.

High ambient temperature14.8 vdc aborbsion limitNo temperature compensationLike baking a cake at 520FDeath to aborbed glass matSlow death by "a thousand cuts" for the flooded batteries. The only battery that could survive (not prosper) in that environment is a calcium/calcium battery which makes it totally unsuitable for cyclingI suggest more research in the area regarding correct voltages for different temperaturesAnd this is anything but a nit-picking comment.

You need a "Charge Wizard" to plug into your Intelipower converter to cycle the charging currents properly so you wont boil your batteries like you are doing. You get what you pay for but I bought two Trojans t-125's 6 volt gc batts. By never letting them discharge below 50% I sold my TT with them them still going strong now 12 years old. My new to me TT 3 years with us, now has the same ones again. Yes they are pricey but look at the length of service. I wouldn't buy the Interstates as they would have been replaced already. We dry camp 50% or greater percent of the time. If your always on the generator I would also get an automatic water system for the cells. Trimetric sells a meter sc-2030 that montiors batt condition and has a temp sensor option. Unless your going to keep replacing batteries, you might want to invest in your power the way I did and not worry about it. This works for us.

Correct???I have a charge wizard, but since I only slightly discharge them, the only reason to use the Wiz, is to boil of the Sulfation that I cause.

is a single 12v flooded out of the running? about 1/2 the price of 2xGC2.

The charge wizard is built in to every 9200 series converter, so you don't want it.You may want the charge pendant if you want to control the stages of charging.Yes, go w/ the cosco 6 volts, you will not have any problem. The float voltage of 13.3 may be a little high in severely hot temps, and may shorten over all batt life a little, but over all you will be fine.
