Understanding the Importance of a Battery Tester

When I first started using power tools, I quickly realized how essential a battery tester is. It allows me to check the health and charge level of my batteries, ensuring that my tools are always ready for use. A battery tester saves me time and frustration by helping me identify weak or dead batteries before I start a project.
