If you change those specs, you need to have the car programmed. There's a few options ranging from 56Ah to 90Ah and the 2 types available for our cars are AGM and lead acid, non-AGM. AGM charging profiles are only available for 70-90Ah ratings. However, I've been running an Braille 21lb battery in my car for about 6 months with no problems. Car was programmed as a 70Ah, AGM. (Braille is 31Ah, AGM, 550CCAs vs stock 90Ah, lead acid (non-AGM), 900CCAs.)

CAs and CCAs should be kept similar to your oem battery.

After you program a battery (aftermarket), it then needs to be registered.

I don't beleive voltage can be set by the user. Only the charging programs that are available by BMW can be activated.

Also:

DDE6 = 318d, 320d, 325d, 330d, 335d (03/2005 - 09/2007)
DDE7 = 318d, 320d, 325d, 330d, 335d (09/2007 -)
MV946 = 316i, 318i, 320i, 320si
MSV70 = 325i, 330i
MSV80 = 328i
MSD80/MSD81 = 325i (N53), 335i
MSS60 = M3
Thanks for the additional info (This is CasperSYTFU)!
