When I was working, I used to have a 2-mile commute, and I went through batteries faster than expected because even a two-mile drive is not enough. Any car that is occasionally used should still be driven ten miles a week not just for the battery but for the suspension and engine lubrication. Running an engine for only a couple of minutes is just enough time to build up water condensation and not dry it out. The engine should be run long enough to fully open the thermostat. If you are just worried about the battery, get a battery tender. They are easy to use and can be quickly connected and disconnected.

Thanks for the thorough, thoughtful & informative reply! A battery tender may be a good investment for me. I do try to do as you say but driving it even when I don’t need to is not always easy to remember to do. I love having a car but I really don’t NEED one most of the time.
