Adding a second battery? - Page 2

I'd go with a Stinger over an Optima any day. I haven't had much luck with Optima batteries at all. As a matter of fact, every Optima I have used in a big system has died a year later and was replaced with a Stinger.

On a large power wire (1/0 or 0/0) I would fuse it at 300A under the hood and in the trunck on the qire that runs through the car. If you dont have it fused on both sides and that wire shorts, you will have a serious fire from the short to the unfused side of the cable.

I have seen 0/0 gauge glow white hot, trust me, it's not a pretty sight. Oh, and no, I didnt burn the car, it was a trainee at a shop I worked of on LI. He also tried to pull the power wire off the battery after it shorted. It's not easy to break a copper weld by hand when the thing you are grabbing is probably about 1500 degrees. It took his skin right down to the bone in a puff of smoke.

yeah thats not good!!! One of the guys at work here said to use nothing less than a 0/0 wire... I mean the bigger the better, to some extent. But whats the whole purpose of the isolator in this?!

My dad has been using optimas in his car for a couple yrs now, and hasnt had a problem.

I think my biggest challenge is going to be finding an alternator for this car. Ill have to check out that one place and see what they have to say.

1/0 and 0/0 is close enough. 0/0 is so hard to work with though. The isolator separates the batteries so you can leave your key on ACC and blast your system til it dies, turn it to IGN and fire your car right up and charge both of them.
