Regarding E90 battery registration

[RenaissanceMan]

When I last changed the battery in our '06 E90 325i a year ago, I was not aware of the need to perform a registration. Given that the battery is now a year old, would there be any reason or benefit to registering it now?

Yes.

Agreed, a proper charging profile will extend the life of your battery.
