View Full Version : Battery location doubts
Jaguar Engineer

I’ve installed the battery in the trunk directly behind the seats as instructed in the manual, but upon standing back and looking at it, it appears that it will be far inside of the actual truck lid opening. Will there be issues removing/replacing the batteries with the hold down studs being near the top of the trunk compartment and close to the body? Any firsthand experience here would be appreciated.

You have the option of installing it in the engine bay too. Breeze makes an excellent battery box (https://www.breezeautomotive.com/shop/engine-compartment-battery-mounting-kit-mk3-3-1-4-roadster/) for this purpose and it makes it very easy to get to the battery.

Several of us have opted to relocate the battery up front. You may want to investigate this option. Several advantages, shorter cable leads and improved access.

I am one of the several Flip Smiley mentioned. Made my own battery box, sorry Mark ( I did buy a lot of your other stuff;) ), and used the space that the ffmetals box goes in as a tool box. Here are some old pictures from the build. I have replaced the battery since then and it was pretty easy to do.

Flip and I made a video of locating our batteries in the engine bay. We talked about the advantages as well. Easy to get to, short battery cables, more trunk space, etc.
https://youtu.be/mUXRIsNmBc4
If you have a 302 or 351W, there is plenty of room in front of the engine.
then you have more space for chairs, tools, blankets, beverages, etc in your trunk.
Thanks,

+1 to CaptB's suggestion. It tucks it away nicely. A small challenge to remove, but I am fashioning a sling to place underneath to help facilitate removal. It will have a handhold on either end, slip underneath the battery, and when it's time, I can just grab the handles and lift.
As far as the long runs, as others have mentioned, just use the right size cable, and that is a nonissue. I also like the idea that the weight is centerline above the IRS.
Either location will work great, but we each have our preference...

Steve

Another Breeze front mounted battery fan here, anything to free up more space in the trunk it is prime real estate in there. Also very easy access to the battery in front of the engine.

Big battery cable solves the wiring issues.

I would like a glove box where the battery is usually installed, so I’m thinking of moving it over to the passenger side tucked under the roll bar. I’m not really concerned about trunk space, so the extra work of a drop or front mount doesn’t seem worth it. Reasonable?

The centre of the trunk floor is reinforced to support the battery in the position directed by the instructions. Outside of this area the battery will be sitting on the aluminum sheeting without support. Not sure if that is a great idea.

Highly recommend antigravity lithium battery rather than Braille. A little more expensive but only 25% of the weight and they seem to be a lot more reliable than the Braille AGMs. Mine only weighs 5lbs and it cranks a high compression 376 way faster than my Braille ever did, and it doesnt lose charge sitting for a month off a tender like the Braille did

If you get a high end lightweight battery you can put it wherever you want. If you have a 50lb battery it needs to have the added support like the "factory" location

Would an Optima Red Top qualify as lightweight?
There’s a 1X1 running diagonally mostly under the intended battery location, too.

A red top is lighter, but not light. If you do move it somewhere else, you need to add a backing plate or secure the battery hold down through a frame member. I would definitely not trust any battery tie down that's simply going into .040 aluminum to restrain a battery in an accident.

Ah, fair point. I had been thinking of fatigue, not an accident.
If I decide I don’t need a heater (TX), the point becomes moot, as I’ll install a glove box in the traditional location.

You can have the heater and a 3 inch deep glove box in the standard location with a little fabrication skills. I made a box that moved the heater 2 1/2 inches forward to allow for this. Here's another old picture.

Mine is mounted on the right side of the lower trunk floor. It doesn't take up to much room, and is easy access for charging or replacement.
I think that was FFR's suggested location for the MK3.1 builds.

Antigravity batteries are really cool, especially with the remote jumpstart option. But I wouldn't say they are "a little more expensive". They're quite a bit more money.
They last longer, require less maintenance and in my opinion are absolutely worth the cost, but still a good amount of $$$ up front.

Not that big of a difference on these cars once youre already comparing the Braille he referenced, the antigravity I have was $350, the Braille is $250. For a new car that has big power demands yeah there is a major difference those can be around $1k.

Could you elaborate on this Cobra Earl drop trunk? Are there instructions or a kit somewhere?
Do a search for "Dropped Trunk Mod", and a half dozen or so will turn up.....Not too hard to do from scratch, but the kits do make it easier if you do not have access to a bending brake or an aluminum source.
I dont think that Cobra Earl is making them anymore, but Russ Thompson http://www.norcal-cobras.com/store/russ_garage/index.html makes a few sets when he gets enough requests.
I did mine about 4 years ago from scratch, and on a completed car. It would have been 10x easier without the body in the way, but it is do-able.
At the same time I moved the battery from the right side of the trunk floor to a clone of a FFMetal box.
Together, it has added an enormous amount of useable room in the trunk.
Highly recommended.
I have the FFmetal box in my 2011 MKIV. Very nice. To be honest, I have the same battery in there since 2012. I ran a charger lead out the trunk and it stays on a tender. I am running a regular big box store battery, nothing fancy.

I replaced mine last year. 8 years after it went in. Easy operation. There is a hole in the bottom so you use a jack and a piece of wood and it pops right out. Then you easily lower the new one down.
It is something that needs to be done every 7 - 10 years. Is access really a concern?
You also don't want to add weight to the front of the car. That is why the engine is so far back. Heat is also not good for a battery.

Cobra Earl is no longer with us. He made a couple of enhancements available to people for years. His drop trunk utilized the space between the middle-to-driver side area of the gas tank, recessing the trunk floor below the 1" rear frame rails that support the as-designed trunk floor along with providing a crunch zone for rear-end collisions presumably. I know there is some other vendor on the forum that supplies similar.

I have the FFMetal box that was mounted in the center of the trunk with a 4 link. Just moved the battery box today so I could mount the 3 link frame in position. This was all done with the car complete and I was able to get my #34 battery in. I still need to do an aluminum patch but it is all covered with carpet so it will not be seen. I like the trunk mount for several reason; it’s in the trunk, it’s hidden and it’s not under my hood. Did I mention, I don’t want my battery under the hood?

Just to offer a point that I haven't seen discussed.
Battery weight and placement might matter to you. Many talk about corner balance and adjusting coilovers to adjust the balance. A good plan from what I've seen. Moving a 40# battery around will change things, good or bad that's up to you and your scales to determine. Perhaps not real important on a street car but more important on a track car.
In a past life and different car the battery was on the driver's side behind the rear wheel. Corner balance wasn't great, way heavy to the left rear. We pulled the battery and placed it over the passenger side headers about 10" in from the outer body. Most of the corner balance issues were resolved or got significantly better. For those cars the left rear was the heavy point, the front right the light. All this was checked on properly used scales.
Another thought about lightweight batteries is securing Mass. It's a whole lot easier to tie down a smaller / lighter item than a larger / heavier piece. I've seen what a 40# battery does in an instantaneous stop.
BTW, I'm regrouping and looking at the ATX20-HD as an option as Hooper has mentioned. Just over 5# and $399 MSRP. Opens up options for placement while reducing concerns for balance.

If using the FFmetal trunk mount kit with solid rear axle:
I have the 289 kit with solid rear axle. I used the FFmetal kit and it initially interfered with the travel of the rear differential. FFmetal is an awesome, well built unit, but I had to modify it by raising it up 2 inches to clear the diff travel.

Until you need to replace the battery!!
FYI, that's what the big hole in the bottom of the box is for. Just put a 4x4 under the battery and use your floor jack to lift it up. Or enlist a friend to get underneath the back of the car and push up. In 17 years, I've removed my battery 3 times by myself and it just lifts right up and out - it's not easy, but totally worth it. The weight in the back in good, the space it frees up is great, I have remote battery terminals in the trunk so I can charge the battery. There's really no negative to having it back there.
Tip: Leave the handle on the battery and use it to lift the battery out in 5-7 years.

My argument for a rear battery.
1. These cars need all the weight in the rear that you can get.
2. Batteries don't like heat.
3. Engine compartment looks better without it.
4. You will likely not need to touch the battery for 7 - 10 years, so it doesn't need to be very serviceable.
5. If you do need to remove it, the FFmetals box has a hole in the bottom. Use a piece of wood and a jack and it pushes it up for easy removal.

FF Metals box will not fit if you’re running a GT500 finned cover on a Ford 8.8 solid axle 3-link. It hits.
I will add this is a super nice piece however and Id like to find a smaller battery that may allow me to notch the box and still use it. Very well made, worth the mod and changing a battery if there’s a sufficiently smaller one.
Any suggestions on battery options would be appreciated.

Good to know, thank you. Pictures? Not sure what a GT500 finned cover looks like. Where on the cover would it have made contact?

Its one of these

Too close across the top.
Dropped 2" right now and am 2" away from the box. once sitting down on wheels it'll be scary close and under compression I am sure will hit.
To Richs point I'm going to revisit trimming the fins.
