Battery Discharge Solution.

[Tmac]

For anyone that is interested, I spoke with BMW today and they said an aftermarket battery will not void the warranty, but the system has to be reprogrammed to accept a new battery with higher cold cranking amps so the vehicle will recharge it fully instead of still thinking it only has to recharge the amount of the stock battery. I realize it is not an ideal solution b/c it costs us money after already paying for the vehicle, but it should resolve the issue, especially for those of us who live in colder areas.
