On my Galaxie I want to mount the battery inside the passanger fender in the trunk since it is out of the way. I cannot fit the battery box in there and out the battery in it so I want to mount it in that spot without the box. Does anyone see a problem I can't think of?
they aren't mounted in boxes from the factory. I've got mine bolted to the floor in the trunk. I take it you got the alternator, brakes, etc fixed now?
Take into consideration that when the battery charges you will get the acid residue in/on the trunk area. acid residue=rust eventually. If they are still available Corvette's had battery caps that had a vent tube to hook hoses to. The only problem you have to use an AC/Delco battery. I did that one in the past and it worked fairly well.
The other issue is the outgassing of the battery, a potentially deadly consequence. Especially in a situation where it is overcharging, the gasses can easily creep through the rear seat area into the passenger compartment. Not a problem up front since firewalls are sealed from the greenhouse, but trunks are not.
Lots of new cars have trunk mounted batteries. They are designed to breath through an external vent. Find one with CCA rating and dimensions you need.
Make sure you put covers or a cover on the positive lead. That way you won't arc anything when your getting something out of the trunk.
Some of the so called sealed batteries are just capless and vent like old batteries. I think only the ones that can be mounted sideway and upside down like Odyssey's are truly sealed. I know Optima's are vented.
when i have done them, mount the battery whereever your gonna put it, then close by, put your starter soleniod, that way you don`t have a huge power cable running all the way from thr back to the front of the car.......and optimas can be mounted in any position, they are vented, but nothing to spill, but there quality has gone down hill in the last few years i have experienced......and use the welding cable, works very good, more finer strands of wire, solder on the lugs that u need and done....will last a long time and be just about bulletproof.....
Well it is an optima and I am going to use the battery extension to have it sit up off the floor a little bit. The amount of cable doesn't bother me because I got a roll for free. I am still waiting on the alternator brackets, but got the master cylinder today and am going out to put it in shortly. So I don't gave to worry about the venting problem with an optima?
i have had optimas in alot of trunks and never had any problems, only time i`ve seen one really gas in on a car with a alternator really overcharging, otherwise pretty clean, and they also don`t have nearly the corrosion problems of normal bateries......good luck
Does anyone know were I could find any terminal covers for a side post? Or I may just make a shield out of aluminum that protects the side I'd the battery
ive taken the petrol tank from under the seat in my 38 chevy pu.was going to put the battery and electrics under the seat looks like i need a odyssey .the only battery that would start my 88 ci stroker shovelhead long term
Batteries for Audis and *ercedes have a vent tube to run through the floor and they are usually low profile and have plenty of power. They go under the back seats in those cars. Boat battery boxes aren't too spendy and should fit in there and usually have the tie down stuff with the* when you buy the*. But fro* experience, batteries in the trunk can be a pain in the***** at ti*es. Tie it down as they like to bounce around if you don't.
Go and look in the trunk of most 1992 onwards BMW's, they are trunk mounted They clamp the battery down at the lip on the bottom of the battery, and use a plastic cover If you're at a junk yard, try and get the factory BMW cables and the little junction box that goes on the inner guard [ for jumper starting ] It'll be cheaper than making cables
just be sure to protect the positive cable if you choose no box. you wouldnt want the frame of an aluminum chair or something to come in contact wth it and cause problems.
A long time ago, I heard it was better to mount the battery crosswise and not lengthwise. The theory was that the force of the battery acid sloshing would not be pushing against the plates on take off. And the plates would not be as prone breaking loose and shorting out. Of course this doesn't have any relavence on a true dry cell battery or an Optima syle battery. Take it for what it's worth (not much). Larry T
Well I'm thinking of making an aluminum sheild in front of the battery with foam backing on it to help since the terminals I'm using can't have covers
Sort of. If the solenoid is in the trunk, near the battery, the only time the heavy cable to the starter is carrying full amperage potential ("hot") is when the starter is activated. You will still need to have a substantial size power lead from the alternator back to the solenoid/battery positive cable in order to charge the battery and/or feed the rest of the vehicle electrical system. If that lead is fused adequately it would protect the system, and in any case, would carry far less amperage than the starter cable if the solenoid is in the front. Ray
Years ago I bolted the battery to the trunk floor of my camaro, and the flexing cracked the metal all to hell. Make sure it is properly supported.
and negative (always same size) and if in enclosed space I prefer AGM (Optima) battery for safety. Have you tried a marine battery box?
