Interstate 12volt golf cart battery

Use Google to find your local Interstate battery dealer. I bought four Interstate industrial golf cart 6 volt batteries that are 235 AH each. So that's 470 AH at 12 volts.

A residential fridge that uses how much electricity? Group 24 batteries aren’t wroth buying at all...usable 35-40 amp hours?

Sadly the industry keeps calling MARINE "dual purpose" batteries "deep cycle" when they are not !

The ONLY COMMONLY AVAILABLE DEEP CYCLE LEAD ACID BATTERIES ARE GOLF CART BATTERIES !

The Link 404ed on me and the batteries Google found make no sense.

A Group 31 is around 130 amp hours but if it is a MARIME/deep cucle you can only use about 25% of that

A Golf Car battery.. As I recall the 12V types are aroud the same capacity but you can use 50% of it. That's the difference. the GOLF CAR batteries are DEEP CYCLE as opposed to MARINE (starting)/deep cycle (note the change of case).

We pick up our used toyhauler next Wednesday. It has a residential fridge. That is where my battery concern starts. Dealer agreed to put in two new group 24 12 volts. I inquired about upgrading to two 31's. They said add $120 as that is what a group 31 would cost them and they can get two 24's for $60 each. Would my best bet still be two 6 volts?

ABSOLUTELY !

As Gdetrailer stated, a pair of "average" 6V GC2 golf cart batteries has the capacity of 210Ah.

A pair of "dual purpose" Group 24 batteries is approximately 150Ah. They cost more than "average" GC2 golf cart batteries

A pair of "dual purpose" Group 31 batteries is approximately 210Ah. They are physically larger than a pair of GC2 or Group 24 batteries. They cost more than "dual purpose" Group 24 batteries


The only reason RV dealers and camping stores sell them is better marketing !

Nothing wrong with Trojan T1275 ... except the price ! :E

Your best bet would be four 6s. Two 6s is better than two 24s or 31s but maybe not enough for what toy haulers might get up to out there! :)

Forget about “reserve” capacity. Deal in amp hours to determine an RV battery’s capably

I must have liked those T-1275s because I used them more like in a scrubber. High inverter draws but not much time doing that in a day.

The golf cars they sold had either four 12v T-1275s or else six 8 volt batts. He said they were going over to use six 8s mostly because ISTR that way the car had more oomph up hill or something like that. Been a while.
