Battery Relocation

[canadian357]

Whats the cheapest/yet not shittiest kit you guys could find?

[Hondamonster]

you don't really need a kit. just put it where you want it and lengthen the power then ground it somewhere sturdy nearby. make sure you retain the ground going from the transmission that went to the negative battery terminal. just ground it to a bolt in the bay so your starter is still grounded. you can pick up a marine battery box at wal mart for 6 bucks, get a 2 or 4 gauge sub wire from a local audio shop with enough wire to lengthen the power and create a new ground and some kind of distribution block to go where the battery was.

short of the long, do it yourself. i spend about 50 for everything.

i paid like 80 bucks from summit.com...not bad for a cheap kit...still havent done it tho...haha

1. Get wire (2/4/6 gauge) (enough to relocate battery to where ever you want it)
2. Run power wire (Red) from alt to battery positive.
3. Route battery negative to solid body ground (ie: strut tower bolt)

Done!

Go to Wal-Mart or Canadian-Tire and get a marine battery box.

17 bucks and your trunk will be safe from fumes and spills.
You can route the box vent to the sunroof drain hole in the trunk for a clean install.

if you aren't running a big stereo, you can run 2 gauge, thats plenty for these cars, you NEED a breaker right at the battery, don't skip this, and don't go cheap, a short will burn your car to the ground faster then you think, you need to tie the alternator to the starter lug,, and the alternator needs to be fused between the power cable, and alternator, the reason for this, is even if a battery breaker blows, the alternator is still putting enough current into that same cable to feed a short. I've said it a hundred times about the box, those marine boxes are NOT safe, the battery needs to be physically bolted to the car body, not strapped, not bungee corded, but bolted down solidly!! people have been KILLED by flying batteries in wrecks, you have a 40 pound object that is going to fly at you with tremendous force in a wreck. the fold down seats WILL NOT stop it, I wish to God I could find that fifth gear episode where they did this in a wreck, put a toolbox in the trunk that didn't even weigh the same as a battery, it came right through the seat back, and decapitated the dummy, in a 25 MPH wreck. your battery will do this, and throw acid all over you in a wreck. I highly recommend using an AGM battery, Odyssey or one like it, there is no free acid in the battery, and they don't out gas in anyway among other reasons

4guage will be fine if you dont have a huge sound system

you are going to lose so much current trying to crank a car with 4 gauge, it will never turn over in cold weather. 4 gauge is fine for the battery cables to the breaker, but you lose a lot of current over a long run, 4 gauge will handle the current, but it has too much loss, I have four gauge for my positive and ground right off of the battery, due to the bends needed, but I run 2 all the way to the front, the reason for that is lower resistance

^^ i need you to redo my batt relocation kit..

[lostforawhile]

OK I found it!! THIS is why you don't put a battery in the back of a car, held with bungee cords or tie down straps, In this fifth gear episode, these are all low speed crash, do you really think a bungee cord is going to hold a 40 pound battery? It doesn't specifically show the battery one, but you'll get the idea. http://www.youtube.com/watch?v=NwO5ZASY994 edit" youtube appears to be down at the second

woooops never mind read it wrong

3g sedan seat latch is much stronger then that, not saying it cant happen but its less of a chance lol
i would just bolt one of thoses plastic boxs in then bolt a tie down bar over the top of battery and thru the frame, wouldn't go anywhere

that toolbox in a 40 g deceleration, weighs more then half a ton, an average battery would be closer to 3/4 of a ton in a deceleration like that, don't kid yourself that the little latches in the three g are going to stop that. And it's not a LOL thing, nothing funny about it, kids who have moved their batteries like that have been decapitated by them, it''s happened before, it will happen again. CAH you have no idea of the forces involved in a collision do you? DO NOT cheap out mounting a battery in the back.

[Civic Accord Honda]

if the battery has a steal bar going over the top with long bolts on each side going down to the frame id like to see it move... thats like saying the bumper is going to fly off because its only had on by 2 12mm studs

i know the force is much stronger when in a accident and people that dont bolt it down thru the frame are idiots but if its properly bolted down its not going to rip the frame out lol

btw i know danger, my car is dangerous enough as it is im sure if my 6x9s were to fly out in a accident it would hurt or kill or if my loose seatbelts were to snap off i would fly thru the windshield my spare tire with no hold down etc,
(note im getting thoses things fixed slowly but surely one thing at a time lol seat belts geting replaced next time i go to junkyard, 6x9 will get bolted in as soon as i find the damn nuts for it spare tire as well i got thoses parts just cant find them anywhere >< tho im just going to take the spare out anyway lol dont have a jack and the lip on the donut is completely rusted out )

I just see so many bad battery relocation's, it's not just if you get in a wreck, it's the energy stored in the battery and what it can do in an unprotected short with a heavy cable. Also I see regular lead acid batteries with no vents in unsealed boxes, this is the result of an unsealed battery explosion ,the resulting fire destroyed the car http://www.cleanmpg.com/photos/data/500/CNG_car_left_side.jpg

[Civic Accord Honda]

well people that use a bunji cord need to be slapped upside the head, im just saying the plastic box is safe if u have a bar going over the top of the battery with thick bolts going to the floor board, and of course have a vent running from the box to a hole in the body

4 gauge will be just fine your not looseing ANYTHING within the 14 or less feet it travels just be sure to have a nice ground made of atleast the same size wire, also as noted adding an inline fuse is a must.

on the tie down part theres a simple fix the stock tie down is removable it can be unbolted and set inside the plastic box noted above, drill holes matching the old bolts and bolt it into your trunk, from there you can use a proper tie down wich you should allready have (if not there a dime a dozzen at junk yards and cost about 9 bucks new. this will give the same if not better bolt down then every aftermarket kit box on the market

If you are going to bolt it in the car, I would use something a little stronger then the factory hold down, it's designed to keep the battery from rattling around, not keep it in place during a wreck.

Does anyone have a diagram or pic of a battery relocate setup,I can't find a distribution block to tie in the cable to the back.

go to my build thread. I have a picture of the fused block I used when I did my relocation. I'm on my phone posting this otherwise I'd post up the link.

[lostforawhile]

I would go back and watch the fifth gear episode a few posts back, then decide, Do I want cheap hardware holding down this battery? is my life worth it? or do I want the 2.99 hold downs? as a matter of fact here's the video again, just image a 40 pound plastic box full of sulfuric acid hurtling through your back seats and straight towards you. http://www.youtube.com/watch?v=NwO5ZASY994

the factory ones do more then keep it from "rattleing around" in a crash they hold it in place still becuse there ment to keep more problems happening after a crash, sparking batts can cause a large problem after a crash and can ignite.


not to mention you keep saying how a 40 lb batt could kill you flying threw the air, well if you have hit something hard enough to send a 40 lb batt to break threw steal tie downs, a plastic batt box, the back of a seat and 8 feet into your skull then you probably have other problems on your hand as a normal persons body weighs 135-190 lbs and if a 40 lb batt can move that much amagine whats left of your body.

also not mentioning the fact that the angle of aproch would have to be perfect, most people mount the batts in the spair tire wheel well or way off to the side were the rear strut tower is in the way, so the flying batt would have to make a 45 degree turn in mid air

[Lil Mike]

you defiantly want a proper hold down, im with lost on this one 100% so many ass clowns just put them in the marine box and butcher the shit out of them. i would use at least a 2 gauge wire.

with a 4 gauge wire you might have problems in the winter starting your car due to the voltage drop along the long wire. i would just get 2 gauge welding cable.

the reason it flys through the air with that much force is the fact it's moving at a high rate of speed, even though the car is stopped, in a 30 mile an hour crash, it will hit the back seat with the force of apx 3/4 of a ton, All i'm saying is you need to use strong enough tie downs to make sure it never moves, in a crash you exert thousands of pounds against the seat belts, the reason it doesn't kill you, is the human body can take hundreds of G's of deceleration for a very short duration. anything in the car will continue to move at the same speed you were moving, even though the car has stopped in the collision, the more mass the object has, the harder it is for it to stop. If you watch that video again, that tool box probably doesn't even weigh as much as an average car battery, you can see the amount of damage it did, with the amount of force generated in a collision, lightweight hardware simply isn't going to be able to contain the object. I'm not running anyone down here, I'm simply trying to point out some information on crash dynamics, I don't want to see anyone killed by something that can be prevented.

that right there is what im talking about

[labeledsk8r]

i know how crash dynamics work and know physics aswell and inertia and all, but it doesnt take much to keep something from moveing, if its tied down with steal tie downs like factory they will stop if not drasticly slow down the inertia. same reason the spair tire is held down by only 1 bolt but somehow has never flew threw a car and killed someone

edit** yep cah thats exactly what i mean

double edit** cah just brought to my atention the 3g uses the side strap style tie down these are trash lol the top tie down bars are what i mean and recomend useing, i forgot i changed out the ones on my 3g for that and my 5th allready came with that style

[stat1K]

i'm sure a spare tire has flown through a car and killed someone, hell i heard from a cop i knew about a lady who lost an ear from a kleenex box, no shit.

makes me want to go get stuff to tie down all my spare tools and such, i need to just take them out of the car as i don't need everything to replace an axle on the side of a highway but i like to be ready in case lol...

as for the tiedown, i wouldn't do it longways like in cah's picture i like the side to side setup across in between the terminals, that way the cable and the terminal will also slow it down in case... i also have 90* mounts on the body of the car to hold the battery from moving forward or back. i've had to stop pretty fast and mine hasn't moved a mm.

[gtmst3]

i used a marene box and 4 bolts with fender washers i bolted it right to the trunk floor it shouldent go anywere
