Does any one know the correct part number or size for a Optimal Yellow Top Battery for our Z4's???

http://www.autozone.com/Ntt,optimal+...iesResults.htm

I'm in Boston and my sister told me that my car's battery is dead. My friend came over and jumped it...it started and left it charging for 15 mins. At night she tried to start it again and its dead.

Car is 4-5 years old...time for a new battery. I want to get teh battery beofre i come home - no down time.

Thanks

4.5lb nano-lithium phosphate. Same power, 1/10th the weight as your stock battery.
Lasts twice as long as lead-acid batteries.

That battery is to pricey for me...499 is too much. And weight saving wont really matter since my z4 is uber slow. I would be great if i had a mz4 and tracked it. Then this would be a buy

I have had better luck with Odyssey Batteries than Optimas, you would have to figure out a mounting solution or use one of the billet mounts available.

If you go with the Optima. Go with the redtop.
