This tester is designed for testing 12v batteries. Each tester is individually computer calibrated for accuracy, and designed for durability and crush resistance, to make this the most dependable tester on the market. Another attractive feature of this precision instrument is it's size, approx. 1.75 inches wide and 2.5 inches tall it can be carried with you easily. Unlike a volt meter, this unit puts the battery under a slight load test, to knock down any surface charge that may exist. Volt meters only measure the voltage without any load. This could result in an inaccurate test.
