7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

BMW has a charging system which is much intelligent than other cars. It charges the battery based on the age of battery. So the charging applied to the battery is directly proportional to its age. Older batteries cannot take the charge that a new battery can take.

So in essence, if you do not register your new battery, then the charging system will treat it as an old battery at the time of charging which will not be a good thing for the life of the battery.

Your car will still operate but the life of the new battery will be compromised.

Correct, the alternator will attempt to charge the battery based on its age. If it is still programmed to the old battery it will over charge. It must be registered/reprogrammed with one of 3 programs Inpa, DIS or Rheingold. All can be found on the forums.

Hmm....

I hear you. To me, charging the battery based on its age just seems like a crazy approach. It ought to be a simple replenishment of required charge irrespective of the age, like my 98 Audi A8 with 240K miles with the original Audi/Bosch battery that still functions like a brand new one!!! I understand that it does not have quite as many parasites as the 07 750Li that compromise the battery. Makes me wonder which is a better system.

Getting a new battery

Well, I'm off to the dealer tomorrow for a new battery, I had read so many threads regarding the battery replacement that I decide to get the real deal, I will let you know the final cost tomorrow.
This is the original battery with a stamp of 25 08 on the battery post, it was built the 25th week of 2008, unless my information is wrong, that's pretty good for a OEM battery.

lRL.. Good luck.make sure they register the battery. I had a dealer in Phoenix change one out in the driveway of the dealership. Before I knew about registration. 3 Hour Drive from Phoenix to Yuma. Car was acting funny when I got home. Only to find out that they forgot to register the battery. So even they make mistakes.

Just got back from the dealership

The battery was replaced by a 92H 900CCA.
Here's the breakdown Battery 326.47 Labor 119.00 Misc 17.85 and MI sales taxes 20.66 for a grand total of $483.98.
Expensive ? yes & no, I have the right part, registered and it seems that the car is working better, I was having warm air coming at my feet, which I did not feel before.
They say that the car is smart enough to shout down accessories when the battery is getting low.
This is the price of ownership, considering the car I am driving, I find that the cost is justified.

That PepBoys battery is 850CCA, ours are 900CCA. Don't they have to be the same?
