Battery registration question
Bought a used 2009 X5 and the battery has obviously been replaced. (I asked this question in X5 forum with no answers.) Two questions:
1- Is there any way to know if the battery was registered? 2- Any harm in registering it again? Here's a screenshot from Bimmercode: |

I believe registration is to allow IBS to adjust charge rate appropriately for the age of the battery.
So if you re-register an older battery (telling the car it has a new battery effectively) then charge rate may not be high enough to keep it properly charged. Would the world end? I like to think not but who knows if weird things may start to happen. |
