    It seems from what I have read on the subject , that the car will be adjusted over time to give more and more charge as the battery gets less efficient with age. So when you fit a new battery it will be charging the new battery at the same rate as the knackered one and over charge it and ruin the battery. Don't take this as gospel but it seems to be the case when I have searched about it.

    Actually, a new battery will charge to a higher voltage than an old battery so registering it should increase the charge voltage.
    What makes me sceptical about this battery registering is, a)batteries in BMWs don't appear to last any longer than cars with "basic"charge circuits. b)The batteries are only ever in the rapid charge phase in a car as journeys are seldom over 4 hours long so there is no time for any fancy charge profiles and c)I was looking for a difference in charge voltage after changing my battery and there wasn't one.

    When I had my battery changed 3 yrs ago they plugged something into to OBD to keep my settings then changed the battery.
    Don't remember them registering anything,but that was three yrs ago.
    Battery has been good and I didn't get charged for any registering procedure,mind u this was not at a stealers.
