Group 31M Battery
Finally pulled the trigger on a Group 31 battery swap. I decided against dual batteries for the weight/complication and the fact that a lot of folks seem plenty happy with a single group 31 under the hood. Besides, I'll likely have two more of these in the camper when that project gets rolling...that's enough complication for me! To get the much larger Group 31 to fit, you need a way to hold it down. There are several ways I've seen people do this but the Pelfrybuilt battery cage is the cleanest I've seen. Plus, as I found out from my purchase, they are super fantastic to work with!
Here's the battery cage. It's pretty nice. I don't care for the look of the top part of the cage (I liked the original version much better) but that's a small nit to pick. It's all stainless steel but I opted for powdercoating anyway cuz I'm smrt like that. :drool:

First step is to pull your old battery and 'tray' out. The tray is just a piece of plastic that sits at the bottom. Here's what you're left with. I cleaned it up and put a coat of wax on it...you know, for fun.

You'll notice that the Pelfrey cage has two different height J hook mounts. The high one goes toward the back...it's obvious when you try to fit it.

Put the tray in loose at first. As you tighten the J hooks it'll distort the cage. Put the battery in and clamp the top part of the cage down...THEN tighten the J hooks until everything is secure. Hook up your cables and you're good to go! Clean.

Two things to note: 1. The main wiring harness that the positive battery cable comes out of as well as the hose (power steering/AC??...didn't really check which) that goes into the radiator in that area sit on or very near the edge of the battery cage. I'll likely add extra protection to both of those to ward of abrasion issues. 2. The positive battery cable is TIGHT. I'll likely lengthen it a bit when I finish wiring my aux fuse block.

Done. Now it's ready for the winch and aux fuse block!
And, yes, I know it's filthy under the hood. It's easy to neglect such things when you live in an apartment complex. Now that we're in a house, I should be able to keep up on that stuff a lot better.
