No, an E83 does not have the built-in capability of accepting battery information like later models do.

It's at least partly to do with BMW's migration to AGM or gel batteries - they have somewhat different charging needs.

Another factor is the never ending quest for more power and better m.p.g. by reducing the drag from an engaged alternator whenever possible.
