2003 BMW Z4 4 cyl Two Wheel Drive Automatic 76000 miles
I need to replace the original battery in my 2003 Z4. Is there any special precauton I need to take before disconnecting the old battery? I'm concerned about losing any stored information or damaging computer software during the time when there is no battery connected.
