I've had a $10 harbor Freight digital caliper for maybe 4 months now and still on the same battery. It could just be luck. I think our sample sets are to small to be statistically relevant.
My _guess_ is that the electronics inside is some small chip that is made in only one place and the expensive and cheap calipers use the same part inside.

As I mentioned in March, I bought a pair of Z-Limit digital calipers from LMS (#4251) and I was going to test them to see if they ate batteries like my inexpensive digital calipers. The "test" was just letting them sit around (with occasional use) to see if the batteries went dead. It's been two months and the batteries are fine, so the calipers officially pass. These calipers are also usefully more precise, reading to .0005" instead of .001"I realize the difference in price between these and my inexpensive digital calipers (#1758, also from LMS) would buy a hell of a lot of batteries, but the inconvenience of picking up a measuring tool and having to stop the work you were doing in order to fool around with it and get it working right is worth it to me, even if I had a shoe box full of batteries under my workbench.Mike Taglieri
