I have a 06 coupe with uncoated LG headers and Im still on my original battery. I dont see how you can be cooking batteries like that.

 

As heavy as a battery is, I would be concerned about whether the rear compartment floor will support the weight without a frame member under it. The Z06 battery is on the right and I think there is an extension from the frame to support the weight. Not so sure that the left side is designed for the added weight.

 

The same bracket exists on the left side, and in the Coupe's case, they are both steel, crimped like an I-beam. If it were Al as on the Z, I might worry, but not with 2mm thick steel. Believe me, there is more than enough strength there.

 

Wish I knew. The original Delco went about a year, the first Exide failed in 11 mos, and the latest one 12 months. Exide doesn't get very good reviews, so maybe it is a poor battery, but there is no doubt the cells closest to the heat were dead and the others were OK. I do drive the car very hard, almost race-like conditions, so there is more heat there.

 

Awesome!

 

I just finished installing a Braille (15 pound) battery in my o8. A little more time consuming than I thought. The small Braille Battery fit perfectly in the smaller rear compartment. I did not have to re-locate any of the electronics in that compartment. I purchased a good quality 4 guage wire from Boat Owners Wharehouse. I did not have to drill any holes in the fire wall or any other location. I found some wires under the rear carpet and threaded the new battery cable through those openings ( no new holes needed). I then traced these wires to the engine compartment and through the allready made hole in the firewall. All the new cable is in the car and tucked under the passenger side carpet. This is the exact location that GM ran their wires from the engine to the rear of the car. The only holes that had to be drilled was for the battery hold down bracket which was supplied with the Braille Battery. Very neat installation and nothing exposed to the elements. The high quality marine grade 4 guage wire is all that is needed. I used approx 13 feet of red and 13 feet of black. I would guestamate the weight of the cable to be about 5 pounds. I hope this helps anyone attempting to relocate there battery. The reason I chose the Braille battery is because if the small size. If you own any year C6 other than the 08...you could use almost any battery. But the 08 has some extra stuff in that compartment for on-star making it almost imposible to install a full size battery. The compete install took about 4 hours.

 

nice

 

FYI: Just bought 25 ft of 1 gauge welding cable. It's 7.8 lbs & I only plan on using about 20 ft. of it in total. The cost was $55 + tx & connectors.
