This tester is designed for testing 12 volt batteries only. Each tester is individually computer calibrated for accuracy, and designed for durability and crush resistance.
Another attractive feature of this precision instrument is its size. At approximately 1.75" wide by 2.5" tall and it can easily be carried with you! Perfect for around the deer lease or farm to keep tabs on your feeder battery life.
BAD BATTERIES MAY STILL SHOW A POSITIVE CHARGE WHEN USING A VOLTMETER! To properly test a battery, you should use a tester that puts a slight load on the battery... like the HCR Battery Tester!
