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.
