Time for new batteries. I did a search, but couldn't find what I was looking for. What sizes will fit without modifications and which will afford the best performance? Additional terminals would also be helpful considering all the junk I have hanging off the clamp bolts.

hey i just picked up 2 batteries for my 2006 and i went with either group 31 or 32 cant remember they are a bit taller and they are narrower only mod is a hold down.
i got them right from cummins canada they are 900 cca
i paid $89.00 Canadian each
best price i have ever seen for batteries of that size!!!

My receipts are lost somewhere in storage, but I think the last ones I got were group 27's. I use a group 31 in my 1st gen. It is a lot larger and I don't think they will fit in my 2nd gen.

27 is what the 2nd gens came with. 65's came in the 3rd gen. 65's are better and will fix in the battery boxes but most hold downs are too small. I "conformed" mine to fit over 65's...

Finally got round to it after it died again from sitting for a month and a half. Got a couple of O'Really's 840 CCA group 27s for $300 for the pair. One of the old batteries was a 7 year old reman, the other an Exide with unknown years on it. I fried my multi-meter trying to check the voltage drain, but I had it on the wrong setting. That will give me an excuse to by a Fluke.

I have excuses.
I had to get my new house livable then move in.
Too much overtime at the new job slowing down the repairs.
Winter. A lot of snow and below zero temps with no shelter.
Unemployment.
Everything shut down.
Other projects taking priority like my other truck that sat dead sense fall.
Besides, as long as the truck didn't sit for more than a week and was plugged in it would start.

65's don't fit in the battery box, at least in 2002's like mine. You have to cut off the lower edge tabs, for applications that use clamps down low on the battery and then modify the plastic hold down bracket. I've done this to 3 sets of batteries now because I prefer the 65's over 27's.
I always say to myself as I'm cutting them "**** thing better be good or I'm screwed for warranty!"

I replaced mine in February with Group 27's from Les Schwab, the old ones were from 2011 so I guess I got my use out of them....
