Battery decision
The battery my car came with (Die-hard 880cca) finally ate the dirt after the car sat for a few weeks. A whole day of charging and a test showed 5.3 volts. Not sure how this happened as the car was a daily up until I garaged it and it would always take a jump from my portable jump pack if it died. Suddenly its totally shot..
Anyways, time for a new bat. So here's the deal. The car is no longer a daily driver and is used as my drag car. I am considering putting in a light weight battery to really shave some weight off the front end.
I would use the car for the night and disconnect the little battery as the car sits in the garage.
Some opinions and info would be great. Do these little 13-15lb batteries come in the necessary CCA? Will it last for a night of starts? If anyone runs one, which is it? Which ones will work for our cars? Etc.
Also what is the actual CCA and reserve the C5 requires? Not sure if the bat I had was the right one.

I have seen that some guys use the Deka ETX18L. I guess I'm having trouble understanding how a 330 cca battery starts our cars that use 800+ cca batteries...
I guess cca doesn't play a role in that?
Im looking for a small battery like this that will accept the side mount wires. Seems hard to find.

Here is a video link by an expert discussing C5 battery requirements that are tied to reserve capacity. Based on your year car there are one of two options. You will see this information right off the bat in the video. These ARE the requirements.

Wrong. The C5 is a battery eater. You need that reserve capacity for many other issues. His topic was just to discuss CL issues. Proceed at your own peril if you want to something different. After all, they only spent a "little" time at GM designing the systems. If you do some research you will see how many issues are caused by low battery capacity. At least one or two a day here on the Forum.

Oh, duh, my column does lock.
Anyways I gave up and got a yellow top optima with 780cca and 120 reserve capacity. According to the video above, 700cca and 120 rc is required. Should be a good bat.
