Most battery testers only measure a batteries "standing" voltage, which is not a good indicator of battery life. The best way to truly test a battery is with a "load" test. A "load " is a small amount of resistance added to the test cycle to simulate a battery in actual use (this is how they test automobile batteries). Our battery tester has selectable "load" settings that maximizes accuracy and verification of true batter life. The results are then displayed on an easy to read LCD display. Readings are then compared to the battery life chart included with the instructions. This battery tester is a must for anyone who uses a wide variety of batteries. For use testing these battery types. AAA AA C D 9 volt 12 volt most button type. Show more
