I am waiting on some parts to finish up some work on my CRD. My battery is old, tired, and in need of replacing. I know that I can trim the tray and fit a group 65 battery in there for a slight improvement. I am also installing a grid heater from a Duramax to improve starting in the northern climate. I suspect the added amp draw would tax even a group 65 batter. I would love to fit a second battery under the hood.

Does anyone have experience starting with a grid heater? Will the group 65 be sufficient (it gets to 0F and sometimes lower on occasion)?

Has anyone successfully gotten a second battery under the hood? If the intake box was gone somehow that would help. I also noticed that if I turned the stock battery 90 and did a little work over there I might be able to squeeze two in side by side. Height will become an issue and restriction though. I would probably need to extend a wiring harness a little but I think I could make it work. It would be pretty spectacular to have two stock batteries in there.

I doubt very seriously you can find room under the hood for a second battery unless you remove the air box and find some other way to filter the incoming air.
I do remember reading a few years ago on LOST of someone adding a larger second battery in the rear of their Jeep in the cargo area... :roll:

I've seen batteries mounted under the seat. However id make sure it's a sealed battery so you don't get the smell.

I think I am going to try two smaller batteries with side terminals. They wont sit down in the tray as well and this will stop and hood contact concerns. Total CCA should be between 1200 and 1300.

If you purchase a Group 65 AGM battery like the NorthStar, it has some pretty impressive numbers. :shock:
And it will fit using the Weeks battery tray (SasquatchParts.com), I have this setup in my Jeep.

SPECIFICATIONS
Pulse (5-second) Hot Cranking Amps (PHCA) -- 1750
Cold Cranking Amps (CCA) -- 1070
20Hr Nominal Capacity (Ah) -- 69
Reserve Capacity Minutes -- 135

I have fitted a larger battery in my 2002 Export 2.5 CRD by cutting the battery tray to take a longer battery.

I have seen some posts a long time ago whereby owners have cut out the right-rear side plastic section inside the cargo bay...just in front of the right-rear wheel arch...with a hinge on the plastic section that has been cutout so as to close it up again.

Then they fix another battery in there with thick cables running up front and some very large switches under the hood so as to select the front battery or the rear battery or both in parallel.

This was mainly for Campers who may need to run refrigerators, lamps, heaters etc. from their KJ battery.....sounds like a lot of work.....rather try the Weeks battery Tray as suggested :wink:

BillyBob -
Interesting concept I will keep that in mind if I abandon the under the hood approach. I want to preserve the precious interior cargo space as best I can until then.

WWDiesel -
Do you have a heater installed in your EGR eliminating elbow?
Also, when I look up that super battery it says CCAs equal 930. I think you are accidently referencing the CA. Either way, two decent batteries would be cheaper and have a greater output (IF I can fit them).

The Odyssey PC1750 is higher rated and cheaper on Amazon.

Mine test at over 1200cca's while only being rated at 950cca.

Your not going to get 2 smaller batteries to have more output for cheaper,your looking at some exotic batteries to fit in that space and have over 600cca's which cost about twice as a PC1750(each and can not be charged by the alternator),forget about side terminals in that size also.

Winter starting performance is greatly assisted by having the right glow plugs with the right software - it appears to be a mismatch, but the 5V metal plugs with the 7V programming has been quite successful this year from both personal experience as well as reports from the field.

I'm talking about two batteries smaller than stock but not each half stock size. That wouldn't gain anything. Battery capacity is a game of surface area and the sizes are generally reflective of their output (some squeeze move surface area in less space achieving higher capacities but at a higher cost). I am talking about two group 101 batteries for example. They are each smaller with less capacity but I would have a CHANCE of squeezing both in and netting 1300cca. Each of those batteries can be had for 100 bucks with a 4 year warranty.

I have the EcoTune and eTecno plugs. I replaced the ceramic plugs when the eTecnos went in. Does this help me know what the settings are? Are talking about deliberately overloading the steelies then?

I think this means I have the 7 volt plugs and the settings remain at 7 volts.

Let us know what you use and how well it works.
I have an old British diesel tractor with an attitude that I replaced the 12V battery with (1) 6v and (1) 8v wired in series. Looks strange but definitely helps wake it up. Also replaced the generator with an old AC Delco alternator externally regulated.

Yes, you would have the 7v plugs as well as the 7v software. TOSS those Etechno plugs and put in a set of 5v Bosch. Yes you would be intentionally "overpowering" them, but nobody has reported any failures even after multiple (three) winters on them and I can personally state from experience that the CRD starts like it is a summer day when it is in the teens out. MUCH BETTER performance. As it should have been from the beginning.

The Duramax LLY grid heater is in also. Anyone installing this heater needs to cut their own gasket and not reuse the metal gasket. It acted like a reed and sound like my Jeep was powered by a Black Rider from Lord of the Rings (Nazgûl) as it leaked boosted air. I reused the stock elbow and attached the grid heater and its’ flanged hose barb to that. The Mishimoto hose was perfect length and placement. The Duramax hose barb is about 0.25 inches bigger so it took some effort and silicon lube to slip the hose in place. (skip the sex jokes)

The fuse box can be easily flipped to the other side of the batteries as show. I still need to mount that box permanently. I cut a flat aluminum tray and bent one side up on the engine side. I welded some brackets on to retain the batteries and used rubber where I could to promote vibration absorption. There is an ear welded to the wheel side the re uses one of the old trays mounts. Below the tray is a wood and rubber spacer/support that uses another of the old mounts. It is pretty solid and I can shake the Jeep by the batteries. I did this in a hurry for state inspections so it is not as pretty as I would have liked but darn, I got 1700 cca and it works so I am happy. The Jeep starts totally different now. I didn’t realize how bad the last single battery had gotten. I got the batteries returned at an auto parts store for 60 each.

I will use a starter solenoid for the grid heater. I am told it should draw about 90-110 amps. I am not sure if I will use a battery isolator or not.

A 1970s era Ford starter solenoid should work perfectly for the heater. Are you going to put in on a timer or have a manual button?

Are you running no fan at all?

No fan at all and no problems. It was 87 here a couple days ago and the temp never moved past its normal spot. I bought an electric fan but now I might not install it. Instead I might leave the shroud off and just throw the mechanical fan in when I tow. It would only take 2 min to put back in.

My local parts store has a solenoid that they said is rated for 200 amps. I might try that. I will put it on a momentary switch so that it can't be left on. It will have juice when the button is held down. I think it will only get 30 sec of use at a time and I won't have to worry about accidentally leaving it on which would be very bad.
