Dual battery install in engine compartment
I have a 90 F150 4x4 with the 302, and I want to put another battery in the engine compartment. Has anyone done this? My thought is to relocate the coolant/washer reservior to the other side of the air filter, and that should give me ample room, but it blocks access to the wiring harness and EEC-IV test port. The other thought is to relocate the thermactor canisters/intake and starter solenoid and mount the second battery behind the main battery. Either way sounds good to me. I would like to know if anyone has done this and provide some helpful input.

[font size="1" color="#FF0000"]LAST EDITED ON 13-Apr-01 AT 06:57 PM (EST)[/font][p]Why not put in an Optima battery? Just as much money, but a better battery. I've noticed if it's a better amount of power you want, most people use the Optima Yellow tops. Specifically police departments! Most of the cruisers I've seen are running the yellow tops. I think that's what my next battery in my 88 will be, since you can hear the truck rpms kick down when I turn on my lightbar.

1965 F-100 (just purchased 1/18/01), SWB, 390, C-6 auto. Dual exhaust, Not much else to do to it.
Can see both below.

Dual battery install in engine compartment
The spare battery will be for all my high amperage accessories ( lights, stereo, fan) as well as a backup in case I decide to leave my fog lights on and drain my battery (like I did the other day).

I know abuot the high drain accessories. I have a full police lightbar mounted on my roof, a 50 wat mobile radio, and a 100 watt siren, I have plenty of high drain on mine! It will pull the truck down when you turn it on. That's why I am going to get one of the high amp alternators, and an optima battery.
Look at the police cars, ambulances and all. They have more high drain stuff on them than you could think about. That's why most of the departments have switched to the Optima batteries. Also, if you'll look at what most of the professional stereo competitors are using, again you'll see the optimas.

Dual battery install in engine compartment
I've got the Powermaster 140A alternator and a pretty decent Delco battery, but the security of a backup battery to jump start my truck sure is nice. It also prevents me from having to look for a Good Samaritan to give me a jump.

Check out http://www.wranglernw.com. I just installed their dual battery tray and manager system in my 96 f-150. It alows use of dual stock or dual optimas or combo if you wish. The install was simple and did not block access to anything. Price was $98.90 US ($8000 CAD) for the tray. Right now they are offering free shipping within the US on on-line orders.

Dual battery install in engine compartment
I recently installed a second battery in my 90 F250 4x4 w/ 5.0L.
I splurged and bought the dual battery tray from Wrangler Power Products -- $100 but saved me trying to weld anything and puts both batteries where the first was but turned 90 degrees. I also purchased a heavy duty 200 amp isolator relay from them. Didn't buy wrangler's battery manager and instead built my own with the same functionality in a custom overhead console -- 2 LEDs, a diode so only one lights up depending on power source (ignition or full-time aux) and a toggle switch -- total parts about $3 from Fry's + plastic for console that also holds switches for lights, etc.

Optima is the way to go, never needs water, never leaks lasts a darn long time and power full ! Delco and Interstate Mega Trons are also good but arent as good as a Optima

Westerner1, you will have to have some sort of management system won't you? If you want the alternator to keep both batteries charged you will have to hook them together with a y connection, and with out a diode or something in there, if you leave your lights on, you will just drain both batteries.

The part # for the wrangler power products tray for your year is 34-962, if you want the cable kit it would be 34-962R1 and the battery manager is 34-962BM. I installed all of the above in my truck and the system works great. The battery tray comes complete with holdown bar and "J" hooks.
