Quoting GSTwithPSI:
FWIW, on my relocated trunk battery, I also use a short ground wire which terminates in the trunk area. I've yet to have any issues with the car charging.
I'm not talking about charging the car AT ALL. That's a low current operation. Or even during running conditions where the alternator is doing all the work. I'm talking about high current electrical loads trying to pull through the chassis. The highest load you'll see in an automotive application will be a huge amplifier, which I fully understand is a small percentage of people it's just where I learned this, and the starter trying to start the car. If your battery is in the trunk and the starter is in the front of the car and you are only grounding it via the chassis you are restricting current flow to the starter and not letting it reach its potential power output. Period.
Again. It might start the car %99.9 percent of the time. But you are still restricting it. Like the exhaust situation.
Batteries are real sensitive to heat too. I have a little more of a challenge during a NH winter with 15-40w oil than you probably do in Socal or MD before that.
