    • Digital battery tester, includes alternator and starter motor tests
    • Simply measuring battery voltage is not a true indication of the state of a battery
    • A battery test has (2) aspects to it:
    • First test the voltage of the battery (which is a rough indication if the battery is fully charged)
      • The voltage could show the battery is fully charged but the battery could be badly sulphated and useless
        • So, you also need to test the voltage of the battery under a heavy load condition
    • This is called a Load Test
      • This indicates the ability of the battery to hold and deliver the power it has stored
      • Depending on the size of the battery, this product adds a very high load to the battery (125 Amp)
      • The battery should be able to deliver this load and hold the voltage up at the same time
      • If the battery is unable to deliver the load (and sustain it for this time frame) then the battery is either defective or simply not fully charged when the test was performed
      • This is why it is crucial to ensure the batteries are fully charged before the test is performed to eliminate that possibility
    • To Load Test simply connect the unit to a fully charged 12 Volt battery
      • Adjust the CCA (cold cranking amps) on the screen up to 999A
      • Then press the load button and perform the 10 second test
      • The unit will inform you if the battery is good, weak or bad
    • The unit can also be used to measure the performance of the charging device (alternator / battery charger)
      • This test informs the user whether the charging device is good, weak or bad


    • Heavy duty leads and clamps
    • 125 Amp test load
    • Suitable for (1) 12 Volt battery per test
      • For 24-36 Volt or larger simply split the battery bank
      • Split down to 12 Volt sections for test
    • Battery from 200 - 1000 cold cranking (CCA)
    • Battery from approx 30 - 140Ah rating
    • Tester Indicates extent of battery sulphation / battery condition
    • Includes Battery Voltmeter
    • High voltage load test safety trip at 13 Volts
    • Fast 10 second load tests (2 min wait between tests)
    • Test 12 Volt alternators and starter motors
