battery tester

I use an ancient inexpensive Radio Shack battery tester to check the batteries when a device fails. I often find all the batteries but one or two are just fine. Here is a more modern digital one:

1.5V AA, AAA, C, D and button batteries and separate terminal contacts test 9V batteries. The red calliper grips the battery while it is being tested. It just tests batteries, not light bulbs or similar continuity problems. In most battery testers, you must tell the tester what kind of cell you are testing. If you get it wrong, you can get inaccurate results, or even damage the meter. With this design the tester effectively measures the length of the battery to figure out which kind it is, so you cannot screw up. For some reason, Amazon is almost giving these away.
