Anyone have any advice where to mount the battery? I've thought about next to the fuel cell in the trunk or maybe rear seat area.Any pros or cons?

Put your battery in a battery box and mount it behind the driver's seat.

we run all our cars with the batery in trunk we can't add any weight to the car so we use it to help for tail weight that and the fact that i don't want to be hanging upside down with a broken battery leaking acid on me

I dont care for the batt. next to the fuel cell.Sparks and fuel fumes sounds like asking for trouble.But I have seen many do it.I have mine in a marine plastic box behind my seat with 1/2 inch bolts and an old lapstrap to hold it in place.But I am not sure if thats where it will be next year or not.Just my thoughts

Mine is to the left of the car and over the rear end. I put Charging posts like the drag racers use for easy access without having to remove the trunk just to recharge the battery

I have mine bolted down in a plastic battery box on the left side just in front of the rear axle.

if you are worried about sparks put and old tube on top over of it to cover the terminals.the way i see it if your batery is hooked up right it shouldn't spark at all and you could also run your vent line under the car if you are that worried about it. we used to have to have ours in the trunk in a metal box i'm not sure who the rocket scientist was that came up with that one but luckily we never had any problems as long as you kept alot of tube and foam on the top.

place your battery anywhere you need weight...easy to move...use it just like you would weight that you are adding to your car.

Most all rules prohibit the battery in the trunk with the fuel cell. They will not directly say this, they usuaslly say "no electrical connections in the trunk". This makes it pretty simple to figure out. I ran mine in the trunk for about 4 races till another racer pointed this out to me. I had it VERY secure also. I had 1/8 plate welded to the trunk floor, it was about 18x24 inches. I then had 2 straps that went across the battery to hold it down that went thru the plate and floor and it was bolted further tying the plate down. This baby wasnt going anywhere. The very next race after I moved it behind the seat I spun and got hit at full speed in the rear quarter. It folded my whole assembly over. If the battery would have been there the post's would have been touching the body. Thats not what I want. As posted earlier put it behind the drivers seat. Mount it in a marine box and cover it with an old inner tube. Make it where your hold down straps cover the caps. This should protect both you and it. Good luck

I argee red neck.Even the best connection comes loose and sparks from time to time.Between the matching post and cable.You cannot control circumstance the "proper"place to put a battery is obviously still up in the air.So where ever you put it make sure it is in tight with VERY good conections.Just my 2cents

your right everybody has there own was of doing things just from what i have seen in my years watching and racing i have never seen a fuel cell catch on fire due to the batery sparking the way i see it if you get hit hard enought to make that batery move the guys fan that hit you is going to make just as many sparks on your trunk or bumper but i have seen a guy get pretty messed up because he rolled got knocked out and had his battery leak acid on him if there is a fire in the trunk it is pretty well contained if you have the rear fire wall tined and thats waht we wear fire suits for a fire suit is not acid proof

Pros and cons. to everything this just happens to be one of those subjects.I am just glad we can discuss it like adults.I do see both arguments here.But like I said no perfect anwser.If racing wasnt dangerous we wouldnt want to do it right?I say put it were ever you feel most comfortable.But make it safe non the less.

I would recomend that you use an optima gel cell battery no matter where you mount it, it can't leak if you get upside down and is also a lot less susceptible to vibration damage to the plates,the initial cost is offset by the fact it can be ran several
years without replacement.

Donnie, I've just recently started looking in the direction of the Optima battery and maybe you or someone else could shed some light on something for me. I am assuming that you treat it just like a normal battery in that you can charge it as well as hook it up with an alternator. Is my assumption correct? Thanks in advance.

the optima isn't like a conventinal batt.instead of plates it has six "gel cells" which look a lot like ace bandage rolls,since there are not any plates,or acid,the batt.isn't effected by vibration,and doesn't take a "memory".the really cool thing is you can run them in any position.upside down, on end,any way you want.of course its not recomended treat it just like a normal batt.

Blane, Yes it works just like a regular battery. I have one that I will run next season due to the earlier mentioned posts about acid leaking. My dad was walking around in a wrecking yard and spotted one. The owner told him he could have it for $5.00. It was still under warrarnty but it was not needed. It still works great. The only downfall to these batteries is the weight. Mine is the 935 or 950 cca version(the smallest made I believe) and it weighs about 70 lbs. It is some kind of heavy, looks light but think again. This is not really a drawback to me, I will need the rear weight anyhow. Good luck to all

If you need some weight added to the rear of your car,get 1 of the "BIG" single truck/equipment batteries and put it on the left rear side.by the way they call them big batteries "cat batteries" around here>

hey donnie if you are sneaky you can never have to buy a battery again i do this every year i need a new battery for my "truck" if you get one with a warrente i do the same with starters also never tell them that parts are for your racer cause the warrente is void then

Great question and great answers, I mount the wifes pure stock battery in the trunk in a performance bodies battery holder in front of the fuel cell. If you hit someone the fuel may come forward but highly unlikely. if you get hit fuel will go backwards same if you back into wall. Use the tube on it if you are still unsure and the Gelcell is the best. just remember to use your head and make it safe. the weight in the trunk is where it does you the most good in trunk on left side. I cover ours with tube and clamp the tube to the battery. The fuel cell should not let fuel out if it is a good one.
I watched one of my old cars get MANGLED in the rear end one night and after the race a few of us walked over to the tank and looked at the cell. IT was ABSOLUTLY junk and not a drop of fuel had leaded out. (rubber good)

Run the battery box behind the seat. Mine has been located behind the seat in a plasctic battery box thats bolted down to the floor board and a bungy cord straped around it.

From all of the posts that I've read on the subject of weight jacking, it seems to me that the car should be set up to handle as good as it can be by tuning the chassis first and then using weight and tire pressure to make final adjustments.

I've seen those who don't like any extra weight in the trunk and those who do. The farther back your weight is, the looser your car will be. The higher your weight is the more it will roll the body instead of pushing down on your chassis.

One of the best posts I saw, and many agreed with him, stated that the fuel cell was mounted on the right as far forward as possible, no weight added in the trunk, battery behind the seat as low as possible, and any extra lead mounted inside the driver's compartment as low as possible.

There are many opinions on this and other subjects. My rules only allow the battery behind the driver's seat.

You definitely need to check the rules on this one. At my track, the rule states that the battery can not be in the trunk, and must not be exposed to the driver at all. In other words, if the battery were to break, the driver would be safe from the acid. I personally have a 79 camaro and what I did is cut a hole in the vent area between the fire wall and the windshield. I then installed a galvanized box made up by a local sheet metal place for $10 and riveted it in. I then put the battery in and drilled holes through the firewall and box and ran a piece of threaded rod in with nuts on both ends to hold it down. This was the easiest thing on the whole car. No, I dont have the rear weight the others talked about, but I do have some extra front rightside weight, and it is legal. Again, check the rules at your track.

On my 80 camaro the battery is mounted in the same spot as NYHicks. At first I thought it was a bad idea, but the front is as good a place as any. Where ever you put it, make sure it doesnt move. Any place is good, as long as it stays there.

We're gonna use one of the bigger truck batteries and built a frame where the left rear seat used to be (behind driver, behind X bars).

The base of the frame is welded in a few different places to the frame. That takes care of mounting but not covering terminals.

We're thinking a mud flap and a strap around the battery & frame? Anyone else run across this?

Deak-Jr, I would suggest maybe covering the top of the battery with a mud flap and then wrapping it in some insulation and bungeeing it or duct taping it. The flap would keep the insulation from heating up from the terminals and would soak up the acid if you were to roll and bust the battery. I dont know if this is logical or not, it just popped into my head while I was reading. Just trying to keep my fellow racers safe.
