Well I put a Sears Platinum P-2 in my 04 TJ P-2 TJ write up and found out Jeep had changed things a bit in the 05-06 to make things cheaper (plastic rear hinge cover, battery tiedown, seat material...). So I bought a P-2 and decided to do a new write-up. I prefer the P-2 over the P-1/P-4 because of the larger capacity (930 versus 880 CCA)

First pull out the old battery and put the P-2 in. Loosening the fuse block (4 tabs popped with a screwdriver) makes it a bit easier.


The key is making sure the back/firewall side fits under the clip before pushing the front/bumper side down. As you can see it fits very tightly, but does fit with a bit of force.

The back/firewall side under the clip.


The front/bumper side showing a tight fit.


So far we have been just fitting it in. The fun starts when you notice the plastic securing wedge is too big to fit in.

So the wedge as is.


The wedge trimmed down.



Now it is just a matter of aligning the holes and reusing the stock bolt, all it took was 10 minutes and a couple of skinned knuckles.


Finally put the fuse block back, it just snaps back.

Hope this helps.

Yeah I had been meaning to do the write-up 3 months ago, but with the move thing happening it was put on hold.

Just to be clear, does the modified wedge just keep the battery from sliding? not actually holding the lip of the battery down?

It holds the battery down by sitting on the edge of the battery. I tried as hard as I could and the battery did not move. I was worried about it becomming a projectile in a crash. I would guess it is in as solid as the stock battery. the firewall side of the battery is secured by the clip on the tray, and the bumper side by the wedge the same way the stock battery is. The wedge is just trimmed to take into account the wider battery.

Elwarpo,
Thanks for the heads up...looks like a great mod.
One more question; Is the P2 a dual terminal battery or top post only?

Top post only the only dual post is the P-4 and I do not see it on their site anymore.

After the installation, did you put the fuse box back into it's mounts, or does it need to remain out of them.

What i am wondering is, does it need to be removded just to get the battery in, or does the size of the battery require it to be permanately moved ?

Thanks

Joe,


It is easier to install the battery with the fuse block being moved out of the way. Once installed, it snaps back in place.


See how tight it is:

thanks guys for clearing it up.

time may be near for a replacement, and from what I saw in the specs, I was afraid the larger capacity battery would not fit.

Greg - did you change the battery mount too, or are you a an 04 or earlier ?

Joe,

I put the Diehard P4/dual post in an 04 which dropped right in place due to the top bolt down bracket but within the next few months I forsee having to put the P2 in an 06.

How did you cut the battery hold-down block?

Thanks,

On the 06 TJ, I did not have to cut anything. It bolted right in.

That's great. Thanks for the response. Just to be clear, the 06 did NOT require any modifications?

I threw it in and bolted down the foot plate.

The P-4 fits right in, the P-2 requires a bit of modding in an 05-06 but fits right into an 03-04. I prefer the P-2 over the P-4 because it has 930 versus 880 CCA and is the same price. On the 03-04 they used a top hold down so no mods are needed. In late 04 they cheapened the rubi a bit (different battery hold down, plastic trim beside the battery to stop a wrench from shorting on the body was removed, rear hinges are stamped not cast, cheaper carpet and seat covers...) and went with the wedge hold down. I figured if i was in a situation where i had to winch without the engine running i wanted the biggest battery i could fit.

Ok. So for a p2 to fit in my 06, I'm going to have to cut down my plastic hold down block, correct? What did you guys use to cut the plastic block?

Thanks,

why not just move the engine computer up 1/2 an inch to gain the clearance needed?

grant it it has been a sec since i've looked at one tho.
