But before I do, I'd like to know what battery it uses and how long the battery lasts. I think the DM42 has been out long enough that plenty of people have had to replace its battery(ies).

Please, call me Thomas. Or Mr. Okken, if you prefer last names.

The DM42 uses a single CR2032. From what I hear, worst-case life is about three days, while running programs non-stop; under continuous normal use, where the screen is on but the calculator is mostly idle, it lasts for several weeks, and on standby, several years. If you expect to use it normally, you should be able to go several months on one battery.
