I want to add a 2nd battery and upgrade the alt. I wanted to see some others who added a 2nd battery. How you mounted it and where? Any JY battery trays that work good in the Troopers? Aftermarket trays? I will be adding four 100w lights on the bumper, CB with PA, Radio with separates, amp and sub, another light in the rear and when I find a roof rack I will add a few more lights. So I am thinking the stock system probably will need to be upgraded.

Not familiar with the underhood look of the 6 banger. Some folks remote an auxiliary battery to the rear compartment.

At the risk of hi jacking this thread, I too am interested to see who has installed a second battery, for the 2.6 4 cylinder, and especially any under the hood installs. SoCalChris beat me to the punch.

I don't have two batteries, but I managed to cram a 65 series battery (same battery in the f150-350)
In my trooper. Puts out 850cca and a reserve capacity of 120. You might be able to just get a big optima and make that work out.

Crammed it where? In the stock position? Got any photos of the install?

yep, it's in the stock position. its just a really tight fit, i removed the small intake tube that goes between the headlight and battery for a better fit (i could get it in there with it in position. but it was a very tight fit)

My battery tray was missing the hold down parts. So the battery is "seat belted" in with zip ties.. NOT my doing..
I was looking under the Trooper today and noticed there is a large amount of space under the back seat area. Got me thinking of taking the back seat out and cutting a hole in the floor to install a "hidden" battery. Cut the hole, make a drop in battery box and weld it in. It would also be a great location for powering my amp and extra power outlet in the back.

Very interesting! Thanks for the photos.

Regarding the photo of the 1st gen battery mount next to the fuse box, is the battery a smaller than normal battery? There is not a whole lot of space in that location to mount a 'normal' sized battery.

Here's a 2nd gen tray:



1st gen custom tray:



You could mount a tray to the frame:


Or cut an access panel under the rear seat and fit a box there. There's lots of room under there, particularly on the side without the exhaust.

This is good information. Do you use a red top, yellow top, or equivalent battery?

I like the idea of a battery box under the rear floor from above. Nice spot on pass side.

For batteries I'm loving my Optima blue tops. They are deep cycle and have both auto style and wing nut marine terminals. makes it easy to hook up accessories.

That is a great idea and location. No room on the RS to put a battery in that location.
