The quote by Emmert Wolf “a man is only as good as his tools” can be translated to “a man works better with better tools”.

With this battery tester which is capable of testing 12 different types of batteries, you get to check how many bars a battery has left just like checking the battery on your smartphone, allowing you to make a better decision when it comes to changing (or throwing away) batteries.
