Battery replacement advice

Sorry to bother you guys, I've got a new battery for the wife's 2013 e89 and wondered if there was a recommended procedure for battery charging. I've got a Creator 310 for resetting and codes that might flag up, but anything I should know before attempting the replacement?
Many thanks in advance.
 
So if the new battery is the same capacity then you need a coder to register it…if it’s different capacity you need to code it and register it..

The coder will have it listed as a function…

Of course it’s an AGM battery?
 
Assuming it's the same spec AH / CCA, you can just swap it & it will work, but not optimal.

The car keeps track of the age of battery / cycles etc & adjusts it's charging current to the battery based on this. As the battery ages, the car increases the charge rate to try & keep up.

If you don't register the new battery with the car's electronics, it will still charge at a higher rate than it needs to. Hence you risk problems by ignoring the step of registering.
