  1. Register ALL new battery replacements.
  2. Recode parameters if the battery specs change

Here's a link to a very comprehensive thread that goes into details about registering/coding BMW batteries: https://www.e90post.com/forums/showthread.php?t=1338302
^^^ I second the above. Actually, the IBS needs to know how much energy to expect the battery to have so that it knows how to manage the state-of-charge and ensuring that loads while parked don't drain the battery so far that it won't start.
