[rossoreed]

I have a 2015 F30 which would not start this morning due to a flat battery, TBF it's been struggling on the cold mornings so I should have sorted it earlier...

But, I've picked up a replacement battery from Halfords, and intended to fit it, but then realised that the battery needs registering to the car.

If I fit the battery today, will the car start OK, or not, because it's not registered with the car?
If it could then be driven, I could drive to my local BMW independent garage on Monday when they open, and they can then register the battery with their programmer.

Any advice pls?
