To all those complaining about batteries: in things like digital calipers where most require greater than 1.3V to run, you should use silver batteries rather than alkaline. For reference alkaline coin cells have an “L” as the first character of their “size”/type while silver is “S”.
The voltage in alkaline batteries decreases as they are used and while they have a nominal voltage of 1.5V, by the time they are only half used their voltage has dropped below 1.3V. The voltage curve in silver batteries is rather flat. In addition silver batteries generally have higher capacities for the size. They’re slightly more expensive than alkaline cells but they’re extremely worth it for the application.
