Battery Tester

Don’t wait until the last moment to determine whether your car’s battery will survive another season, test it and get the peace of mind that comes with knowing that when you turn the key to begin cranking the starter, your battery can supply the amps to get your car going. The Digital 12-Volt Battery Load Tester allows you to perform multiple diagnostic functions on automotive and marine batteries with a single device. The unique 3-step design includes an LED polarity checking function to assure correct connection, battery load testing, and alternator/charging system testing with a built-in auto shutoff feature that will engage after 10 seconds.
