How many do we really need to start these things? I have no stereo, will prolly remove the AC soon, as well as power steering, etc.....

I want to install a lightweight battery. I already keep the car on a battery tender. Can I get a little braile battery and trust it to start? I also do not drive it in the winter.

I think the spec is around 600 or 650 CCAs.

Well right but has anyone measured the minimum it actually takes to start? Something in the 300 range?

The "old" rule of thumb was a minimum that equaled your cubic inches. Of course ambient temp (thicker oil when colder), higher compression ratio, etc., etc. all plays into it.

Up north where it got way below freezing, we always used a minimum of 2 times the cubes (example: 350 cubic inches X 2 = 700 CCA).

Here's what came in my 01 from the factory. It cranked perfectly well for over 7 years. I wouldn't get anything weaker than this.
