I need new batteries. Got 8 years from my napa legends. Never get driven in the winter, hell rarely driven at all.. who's running only one battery? What group size and cca? Doesn't have grid heater also.
Thanks

I'm planning on going to 1 battery under the bed on my fummins swap. I've read that Napa group 31s work good, even with guys that do run grid heaters.

I'm wondering if the 31 will fit. Haven't had time to measure.

I got 9yr in Ohio from a group 27 odyssey. Currently running a group 31 my neighbor gave me for helping him. Dropped right into my truck, but he said he had to find taller hold down. Only pictures I have on my phonr.

I installed a single group 31 NSB-AGM31. These guys had the best price out there answered all my questions even though they were very busy and quick shipping Northstar AGM31 Car Audio Battery Group 31. I don't know if I "had" to but I trimmed the tray so it could sit all the way in there without bulging the sides. I'm not a fabrication guy at all but took about 15-20min of air grinding taking my time to make it clean. I understand it is probably the most expensive one, but it's also the best one you can buy and it's made in the U.S.

Do you have a thread started?

bateman · 07-13-2020, 06:38 AM

Gonna use one of the two new Interstates I have. Group 27 I believe. I don’t foresee any problems with no grid heater.

Who sells deka?

zachu812 · 07-13-2020, 07:09 AM

I've been using a single Oriellys group 31 for a couple years with no problems, takes a little work to get it in the tray but it's not too bad. With go grid heaters and a worn out mechanical motor it's enough juice for a full minute of cranking in the winter.

No sir. Build hasn't started yet, just the plans. I have the truck, and the donor. Waiting until I get my lift in the shop and then she goes under the knife

Well, closest I found was 120 miles away. I’ll call my guys tomorrow and see what they say.

95cummins5.9 · 07-13-2020, 10:44 PM

Great, thanks.

If you have a dealer nearby, a Caterpillar group 31 is made by Deka. The 1000cca is part number 115-2422.
