Wait... don't just throw away your batteries just yet! So many times we are not sure if the battery is good to go or not; is it just low on charge or has completely run out and in a hurry we just let it go and order another one. Why waste time and money when there is a better way to test them all in seconds; whether you have any old or new rechargeable batteries and standard ones like 9V; 1.5V; the button batteries or the C; D; and the AA and or the AAA Batteries; old and new. This battery tester is easy to use and has a universal appeal as it comes with an analog display that quickly and conveniently shows Green; Yellow; Or Red color for you to know the current status of the battery power at a glance. What is amazing; it does not require a battery to test other batteries; as it is powered by the battery you are testing; and that's what we call an All-Rounder No Battery Needed Battery Tester! DETAILS: It comes in a soft; plastic carrying case. Tests all types of batteries; old and new. So practical; time-saving; and a money-saving little tester. Does not require a battery to test any of the other batteries. A must-have for your toolbox.
