Subject: Re: <e28> Why not use and optima battery?


I had one in my e28 M5 for the year and a half that I pwned it, and it never faltered. I left the lights on at an airport for 4 days, came back, got it jumped and never had any hesitation the remaing 9 months of ownership.

Of course that was in Portlnad OR where batteries don't get put to the test. I originally got the battery while I was living in upstate NY, but I the car was garaged, and I only drove once in a while that winter.

I'm a big believer in the pricipal that you can never have too many cold cranking amps. The HUGE OE battery that came in the M5 had about 1/2 the amps of the Optima, and was at ;least twice the size.

Good luck,

Michael Nover
