Title: what size/ group battery do you use ?
Post by: tow hook on July 07, 2020, 02:38:27 PM

i got a battery hold down kit from kaiser willys  https://www.kaiserwillys.com/steel-battery-hold-down-kit-fits-46-71-cj-2a-3a-3b-5

and can't seem to find a battery that fits well. if it was a 6volt system then i found a few. but i'm coming up short, a 24 f seems to be the battety but it doesn't fit. k/w said to got to tsc. no luck there :(

what are you guy using ?

thanks

I only run 12 v systems and my “1 favorite is the group 24F.
Fits my tray and the hold down both.

When I selected my battery, I used a chart like this:
https://www.jegs.com/Sizecharts/bcigroup.html

To see how the sizes compared.  I wanted a popular, easy to find group - just in case.

I also researched other classic vehicles that had similar hold-downs like ours.  But, on ours the hold down rods are off-set from center.  In the end, I bought a replacement battery hold down and took it to a shop to have it lengthened.

Also, even though the math worked, I still took it with me into the store to test fit over the batteries.  From what I've seen, the hold down looks different for a 12V vehicle.  I wanted the older style.

I modified my inner fender to allow a series 31 battery 1000CCA its huge same size we use in our dump trucks at work.

Haven't started the engine yet. But I am running a Toyota 6cyl starter so I am sure it will spin my new 140cuin 7.2-1 engine just fine.
