I noticed these today when looking to upgrade to two group 31 DC.

Would this give me more reserve capacity?

Using AH vs RC, but same idea. That 150AH batt (looks like a Trojan ) is less than two 31s at say 100AH each. Two of those 150s would be more than the two 31s

Here is the T-1275. Some Interstate 6s are made by Trojan too, according to an Interstate guy locally. That is the 225AH and the 210AH one, not the 232AH ones.

You DO realize it is rated at 150Ahr AND it costs $238???

WHY, WHY, WHY do people insist on these insanely expensive "12V" batteries???

You want the best "bang" for the money, go with the GC2 6V batteries, one pair gives you 210Ah-225Ah (depends on manufacturer brand) for $180

Two pairs of GC2 (2 "banks") gives you 420Ahr-450Ah of $360..

6V GC2s are popular and most commonly used batteries in Golf carts, this popularity makes this battery size much cheaper over all to manufacture, other battery sizes are not as popular and manufacturers know that they will sit around longer so they manufacture smaller quantities which means cost per is much higher.

You simply will not find any other battery size that is more cost effective with this kind of Ahr capacity.

The max you get with a GR31 is 125 amp hr. Those GC12 are 150 amp hr.
As others have said, your best choice is GC2 (6v golf cart batteries).

Don't forget LY's agonies with his "Screwy 31".

I was very happy with the used T-1275s I got five years out of. They were beat up and not considered ok for golf car use anymore but were still useful for somebody (me!) I posted about them back then.

Scrubber batteries are special purpose. Their ampacity is designed for a scrubber machine and not a golf car. A scrubber under normal conditions draws more amperage for a couple hours work then gets recharged for 14 hours. Golf cars work all day at lower amperage. The scubber will out CCA the Gc but the Gc will out cycle the scrubber. Acid cc to plate sq.in


A scrubber is an expensive and heavy piece of eqvt. These are the fundamental design differences behind the two batteries.

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.

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

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?
