Battery Tester

This tool is used to check the battery's charge status. The result is easily readable on the color-coded scale. It is determined by measuring the electrolyte density. The higher the sulfuric acid content, the denser the electrolyte becomes. The higher the density, the higher the charge status. The tube is made of glass. After use, clean with clear water and allow to dry before the next use. Delivered in a white cardboard box.
