12 volt batterie

STILL mystified as to why trolling and/or marine designated batteries are suggested for non trolling and/or non marine uses.

Thanks everyone!

IF you have the headroom (They are a bit taller) Do give consideration to going with a pair of GC-2 Six volt.. best price is at Sam's Club..

REASON.. Setting aside the features of the six volt pairs over a 12 volt pair for a moment.

The result may well be LESS EXPENSIVE.. that's right.. Often you can get a pair of sixes for less than a pair of 12's.. how's that for an argument in favor of them?

But do comparison shop

Now if you want to know the other advantages and disadvantages we can discuss.. But I went with sixes.

Many battery cases for a G24 battery use a spacer in them. It may hold a G27 (12.1" long) or G29 (13" long) battery. And a G27 is only a few $$ more than a G24.

I would head to Costco and buy two replacements. Type 24 batteries aren't expensive and having two makes a big difference if the power goes out and your forced to use the furnace ... worth ever penny.

TT came with 2 12v batteries. We very seldom boondock. It's time to replace batteries. Want to stay with 12v. Any suggestions?

If you seldom camp without shore power there's really no reason for anything more than a single Group 24 deep cycle / marine battery so the trailer's electric brake breakaway system will be functional, and for those rare occurrences where you may not have shore power available and would like to run your lights, water pump, etc. You haven't indicated which group size batteries these are that you have now but if they're group 24s mounted in group 24 boxes then you might as well get another G24 and just plunk it in one of the boxes. If they're larger G27 batteries then for a few $$ more you'd be better off with a group 27 battery that will fit that size box. If this is the case I'd just grab one with the best price from your local WalMart, Costco, etc.

Single 12v from costco walmart etc is fine. Should say deep cycle.

Buy 2 new Interstate Group 27 12v batteries (or group 29 if they will fit)

Also known as a "deep cycle golf cart battery".

AND save the interconnect cables incase you decide later that you need that second battery.

Go to your local battery specality store and buy a single 12V trolling motor battery.
