What kind of battery is recommended for the E46 M3? Best Bang for the buck

IFX · Mon, Mar-29-2010, 03:33:50 PM

Thanks, do the coopS and regular coop share the same battery?

I put this BMW Lightweight battery in my car, it's a direct bolt in, no modifications needed for it, and it still works for road cars:

BMW - Lightweight Battery (55Ah 480CCA) - 36lb.

Using the same. Love it

Just don't blast your music with the car turned off.

+1 on that for sure

after lots of research i settled on this and have not regretted it since. I had to make a spacer to fit (i have a vert and the coupe does not need the spacer) but still was worth the trouble.

Any weight savings with the Optima redtop?

Anyone used this in cold climates?

What is the CCA of the bosh?

I've used optima red in my other vehicles and they last forever but I doubt any weight savings over a traditional battery, may even be heavier.

i just put a duralast 47 dl recently in my car. It is for the mini cooper but works perfectly in my car. It only like 29 pounds and cost about 100 at autozone.
