Which Group 27 battery

I haven't had any problems with Walmart Everstart 27DC. I checked last time I bought one and was still made by Johnson controls. I called them and the Walmart Everstart 27DC is a true deep cycle. The Walmart Everstart 27MS is the dreaded Marine Starting hybrid deep cycle/starting battery.

I like DEEP CYCLE,, Ill be all those are MARINE/deep cycle (note case).

Thus I'd go with GC-2 from Sam's or DEKA or Interstate, or the local golf car store.

Oh, you pick up an additional 15-40 amp hours.

I have three five year old Interstate group 27 12 volt house batteries that seem to be kind of tired. I was thinking of Sears or Good Sam replacements since I'm not a full timer.

I think two would be enough for my needs.

I don't like 6 volt batteries for a number of my own reasons.

what brand does GS carry? and are they OK?

Our "new to us" 1981 camper came with an older (no date) Group 31 battery that says it is a "maintenance free" NAPA 31-90S HD Commercial. It has screw-in battery caps that are flush with the top instead of higher up caps like usual.

From some digging on the www it seems it is a sort of starting battery with huge cranking amps. No idea of deep cycling ability. It only weighs 56 lbs so not that impressive for weight wrt its size.

Anyway it is "maintenance free" except I can unscrew the caps and use an hydrometer in its cells.

(I have set it aside from the camper and replaced it with two used T-1275s that are still good to go) No idea what to do with this 31 thing that is not dead, but which is not a proper RV battery either AFAIK.

This is a great resource to find out who really makes the battery:

You say batteries.....
If you have two(does)(2). Replace them both with a pair of 6V golf cart batteries in series. You will now have a 220AH bank that will have a great deal more "sense of humor" than anything else you could do.

Why does a battery bank need a sense of humor???

If there's sufficient space, I'd go two 6v GC2, and avoid the hybrids. Second choice would be two 12v.

No more water than I add to my 12v x 27s living on some solar, and a PD9245, I concider them maintenance free !

"Leaning towards the maintenance free Enegizer for $79."

A "maintenance free" battery has yet to be invented. Don't kid yourself, all batteries require regular maintenance if you want optimum performance and longevity.

:C

Unless you have special issues I would go with the low cost Energizer but I am leary of maintenance free.
