New battery installed yesterday, getting 'Increased battery discharge'

[faz]

Hi all,
Just changed the battery in our X5 yesterday during lunch hour at an indy shop (details here) and registered the new battery too. Drove the car to my work and all was good, parked the car for 3 hours there and when leaving work, got the 'Increased Battery Discharge' warning.

Called the indy shop and he suggested to drive it around for a couple of days, perhaps the new battery that has been sitting for a while prior to delivery.

When I arrived home last night, I measured the battery voltage under the hood location and it was 12.7V (engine turned off). Put a trickle charger on it which immediately showed 'charged', while putting a 13.1V voltage on that terminal. Later in the evening I took it for a 30 minute drive on freeway, came back home and parked it as usual (no charger attached).

Checked voltages (under hood) this morning before start 12.5V, and 14.1V with engine running.

Still showing the warning message. Indy shop insists drive it for a couple of days and it should go away on its own.

My wife drives to work 30 miles each way on freeway so we will see after a couple of days, I am hoping this won't be an issue.

This indy shop does mainly BMWs and Mercedes (and others) and are usually well versed in BMW technical issues. Always see V8 engines disassembled to fix valve guides etc. there, they even have stock of BMW parts including batteries in their shop so I am sure they are no stranger to BMW battery changes.

During the battery change, one of the connectors to the dist panel was mistakenly not plugged in, so a few long starts didn't start the car. They plugged it in and all was good. Then also took out and reconnected the black/yellow connector to the side of the battery (were getting a passenger restraint malfunction error that went away). During the registration process, engine was not running and no chargers attached to the car, so all of that could have resulted in excessive discharge of the battery right off the bat.

I will update this thread after a couple of days and let you all know how it goes. If the issue persists, I will have the indy shop check the battery connections, although I was there and saw them tighten all properly (even a bit too much on the positive terminal for my liking).

Any feedback based on my story above will be appreciated.
