If it ain't lightweight, it ain't the right weight.

Default Re: Light weight battery?

I had the Li-Ion battery that was 4 lbs. If I remember correctly it was a 405 cca battery. I should of got the step up from that, which was something around 500 cca and a 5 lb battery. Car is sold, but it did well up until it was drained by accident, while it was getting worked on just before I sold it.

That's what I have in my 69 Mustang, since it needs big cranking power. We also have on in our 95 M3. Works flawlessly. If I get another M3 again, I will probably run the same battery. Can't beat reliability. I will definitely pick up a li-ion for the track, to get down 30 or so lbs easy (for the 69 Mustang).
