When I started the car to leave, the clock was blinking and I had a warning message about low battery.

Is this normal behavior? There was certainly some discharge of the battery over those three days (although not extreme, by any means. Should I be concerned?
Sounds like a little driving will get your battery charged up. We had a thread not too long ago about battery life and reports were quite diverse (3 - 5 yrs generally). The most interesting note that came out of this was a warning from BMW (some owner's manuals) about daily driving habits and keeping the battery charged:

"if your car is driven only for short distances of less than 10 miles over a prolonged period of time, without an occasional drive at highway speeds, the engines (sic) charging system will not maintain the battery."

Somewhat of a challenge for "seniors" who may only go to Costco once per week!
