Review on Digital battery tester 1.5-9V by Dimitar Pashov ᠌

A table of serviceability-faults for 1.2 V batteries is not provided. Children and women are delighted! They began to independently check the batteries and reject the spent ones. Got pros: Great multifunctional tool! A table of the degree of charge of the tested batteries is given! Has some cons: There is no marking "+", "-" on the contact pads for installing batteries! Grandparents who are not trained in basic electrical engineering can install batteries incorrectly and find the right solution only by "poke method".
