Tutorial - Digital Caliper Battery Hack
about 7 years ago
Yep, the inexpensive calipers are incredible battery hogs. The models that automatically turn on when you start to move them also have an annoying tendency to turn themselves on, even if they're just sitting in a drawer. I just take the batteries out of my cheap calipers when I'm not using them.
By comparison, professional-grade calipers (e.g. Mitutoyo, Starrett...) behave quite differently. I have a Mity caliper whose battery lasted at least 5 years. It probably would have lasted longer but the caliper got dropped and the display broke.
No public wish lists :(
