Traceable® Battery Tester checks alkaline, carbon, silver-oxide, mercury, nickel-cadmium, and other batteries. Tests battery voltages from 1.35 to 12 volts on 13 ranges. Accuracy is ¬±5%. Simple color-coded scale immediately indicates battery condition. Individually serial-numbered Traceable® Certificate is provided to indicate traceability to standards provided by NIST (National Institute of Standards and Technology). Provides true resistive load readings equal to real-world usage. Tests batteries under actual operating conditions. Twenty-six precision resistors provide true representative loads for all batteries. Superior to voltmeters that provide only false, no-load values. Pays for itself by eliminating battery replacements. Self-powered; requires no internal battery. Checks any battery in one second. Gold-plated printed circuit board and silver-plated switches ensure both accuracy and a long life. Small (3-1/2 x 2-1/2 x 1- inch) and lightweight (3-oz) unit comes with two test leads (27-1/2-inch- long cables), Traceable® Certificate, and instructions.
