BMW has rules for how to maintain a battery for long term storage.

At least twice a year a thread on xo relates to can't start after long term battery disconnection. Either the lock code through the MID or three EWS loses sync. Either can be resolved but I would know if you have a start code set and what it is first and have access to a scanner that can sync EWS before disconnect battery long term.
