Yep, the three batteries below are all mfg'd by Johnson Controls (just like the Optima), have specs good enough to run the e38/e39 BMW and can be found in most parts of the USA (the interstate can be found in Canada, too) and come with pretty good warranties as well ( 2yr free replacment/5 yr prorated).
This video is a quick bit of help for E39 owners or technicians looking for solutions with the common no start issue regarding the EWS control unit and ignit
I wouldn't unplug the battery while running. This car is super sensitive to current and voltage so that could fry something. Either with your tool or the obc check to see the voltage while running. Should be above 13.5, preferably 13.8+ if I recall. If not, check your voltage regulator before replacing the alternator.
