In fact, I'll say right away, you can use a regular multimeter for $ 5-6, BUT the difference is that the design is more convenient, allows you to check instantly, and not press it with probes and so on. One or two batteries per month can be measured with a multimeter, I have to measure a lot of batteries every day due to my work, and then the homemade came right by the way. The battery was used from an old smartphone.
The simplest homemade test for the suitability and capacity of batteries of all kinds. Crown, tablet, finger, pinky, AA (AA), AAA (AAA), lithium (Li-ion), 18650, alkaline, salt, duracell, energizer, CR14250.
Battery tester, Tester, Multimeter, testing, capacity measurement, battery, quick measurement.

Болт + гайка провод закрепить лучше. И трубку использовать как проводник...
