Got a battery question
 

Hi guys/gals. I tried doing a search, but did not come up with the answers I was looking for.
I hope someone will be able to help me out with this. I have a '99 Camaro SS and I would like to replace the stock battery, because I have to charge it up a lot. I rarely drive the car. Now, how would I go about doing this? If someone could walk me through the steps one by one, I would really appreciate it. Thanks!!:) :thumbsup: :cheers:

I'm not trying to be a wise guy here.
I just want to make sure I do not mess anything up.
Does it matter which terminal I unhook first, the negative or postive? Will this affect my pcm in any way by swapping out my battery?
Please help guys!!!:willy:
THANK YOU!!!:cheers:

For Real?
Ok, Its a good idea to disconect the negative first and then the positive. Then just unbolt, swap batteries, bolt new battery in, connect your positive and then your negative.

You may want to find out of the ECU has a backup battery but I can't imagine it NOT having some sort of backup system like that!

If you car sits for long periods of time, I'd highly recommend a battery tender. It's $30 well spent.

negative first as that kills the positive. The computer will retain it's tune, but will lose all the short/long term trims, etc., so it will re-learn the tune as you drive it again. Totally normal and you'll likely never even notice anything.

Do not disconnect right before a smog, or if you do drive at least 75-100 miles with varied driving parameters or more so the computer re-learns and resets codes.

Thanks guys.
Newbie here in that dept. I was worried about messing up the pcm/driveability of the car if not done correctly. Again, THANK YOU!!!!:thumbsup: :cheers:
