Battery In Trunk

[94GPGTP]

Has anyone mounted there battery in the trunk?? What did you use to mount it? I was thinking about mounting it in the trunk but not sure where.. I have a 95 GTP.. So far i have upgraded the charging system and have used 0/1 AWG on everything.. From the Alt top the + and From the + to the AUX and From the AUX to the trunk.. Also From - to the Engine block.. I was thinking about doing a CIA through the fender so that is one reason to put it in the trunk.. How do you go with connecting the - if the battery in in the trunk?

I have the battery in the back of my trooper. It frees up a lot of under hood space in that truck. First off you need a box, I would run a breaker and use some welding cable. You should also run a SEALED battery like and Orbital or Optima. They do not release any gases unless they are severely overcharged and the safety vents blow open.

My system uses 0/1 welding cable with a 200A breaker right at the battery. The negative cable runs through the floor right to the frame, at the front of the truck it jumps from the frame to the engine block. The positive cable runs right to the front of the truck and connects to the starter cable, and alternator charge wire. I also have jumper posts at the front so I can do a jump start from the front or rear.

I make all my wire ends by using copper pipe. I flatten the pipe over the wire and then solder it. It makes an extremely strong end and very good electrical conductivity. I just clean them up and round over the ends to make it look factory. This also lets you drill any size hole you want. The pre cast copper ones at the welding store only came with 1/2" holes.

I believe the new Diehard Platinum battery is better than the Optima. It uses virgin lead, is sealed and makes the most use of the space it takes up with a square shape allowing it to utilize its full area instead of the 6 pack design the Optima has which can't use the space between the round cells to generate power.

Sears discontinued the Optima offering in favor of the Platinum series which puts out some pretty serious cranking amps at $180 a pop. First four years of ownership if it fails it's replaced free, afterwards it is prorated up to the 100th month from date of purchase.

I was considering one for my Fiero along with a battery move to the front of the car but in addition to the high CCA of the platinum Diehard is a considerable weight increase compared to the average car battery. The Marine batteries are even heavier and more powerful.

Yea those batteries feature a mat that holds the acid just like the Optima and Orbitals. But they are stacked not wound. Both use the same 99.99% Pure lead. But the reason the spiral wound ones are so good is because the tightly would construction makes is very durable.

Or just use an AcDelco because they have warranty... Are sealed, and GM spent 1 billion dollars on battery research...

I have a relocation on my white beretta, drilled 7/8?" holes then used PCV valve cover grommets where it goes through the trunk, and the engine bay. Took the stock engine to battery ground, and grounded it to the body, then grounded the battery in the trunk to the chassis. The power side I just routed to the starter like the stocker. Used welding cable and a battery box off of summit and copper battery eyelit terminals. Used it now for 2 years without any charging/starting problems. Not sure why betterthan used a 200A breaker, but w/e. Some people route the cable under the car and just zip tie it to the brake lines, I prefered just running it through the car under the carpet takes a little more time but you have more piece of mind (cable wont drag, get caught on anything, cut, etc). Just make sure that if the cable may rub anywhere, that you will put some sort of extra insulation on it - convoluted tubing or w/e.

A breaker is protection for the wiring. If you ever go through that jacket and the positive cable to the front contacts the ground you have the full output of the battery shorting out. You will have either a fire, battery explosion or both. You need either a fusible link, fuse or a breaker. I chose a breaker because it lets me shut off the battery for any service work that might require it. GM has trunk mounted batteries now but I am not sure what they use for protection.

I have made a FWCAI for a 95 GTP (3.4tdc) and if anyone knows that engine bay, it's not very spacious. The battery is still in its STOCK location and it didn't take that long to make the FWCAI.
I would keep the battery up front, throwing it in the back should be your last option. Being fwd, you'll want to keep as much weight up front as possible.

DO YOU HAVE ANY PICS? DID YOU TURN THE BATTERY? WHAT SIZE PIPING DID YOU USE? I'M ACTUALLY LOOKING FORWARD TO DOING THE FWCIA

I will have to ask my buddy if he doesn't mind me posting his pictures up. I used 3" piping.

Yea hopefully he doent mind..
