This Battery Analyzer is made to test the condition of the automotive battery using the latest battery testing technology. Unlike the conventional method of draining the battery by applying resistance load and obtain the result from the meter gauge. Also, it utilizes a series of pulsed voltage across the battery cells and observes the AC current that flows in response to it.
 
The benefits of this test method are:

    Passive testing method is safe.
    Never discharges or drain the battery.
    Able to test condition of discharged battery.
    Consistent and repeatable results.
    Provides unique indication of battery conditions.

Plus, it checks the Alternator's charging and Starter's cranking conditions.

It is maintenance free and no internal batteries required.  It powers up when it is connected to the battery posts during testing.
