This machine is for 12V & 24V Lead-Acid vehicle battery.
Please don’t store the machine in high temp or humidity place. It’ll
damage the machine.
The working voltage range is 9V~35V DC.
Please operate after turn on the headlight 3~5 minutes to clean the
surface voltage when the battery was just full recharged.
The bad connect cable between 2pcs of 12V battery (24V system) will
cause the wrong result. Please check individual battery to ensure.

The voltage should be above 9.2V when cranking.
Please test the battery before testing the alternator and crank motor. The bad
battery will affect the result of alternator and crank motor testing.
We should test the crank motor particularly when the voltage is under 9.2V,
but the result of battery testing is good.
Please change a good battery then start this test if the battery marked as

Traditional test method (1/2 CCA Load Test)
A deep discharge test simulating the demands imposed on a battery. Test the
ability to deliver a starter motor's cranking current requirements while
maintaining a terminal post voltage above a minimum standard.
Apply a load equal to 1/2 the CCA rating for 15 seconds and measure the
voltage drop. Compare the voltage to a voltage chart.
The battery state -of-charge must be 75% (12.4 v) to perform a 1/2 CCA test. If
the battery is below 75% state-of-charge, it must be charged before testing.
New Measurement Techniques:
Ohmic Measurement
Resistance Measurements(DC method)
Impedance Measurements(AC method)
Conductance Measurements(AC method)
Resistance Measurement
Resistance measurements can be performed by applying a load across the
cell/unit and measuring the step change in voltage and current. The Ohmic
value is calculated by dividing the change in voltage by the change in current.

Impedance Measurements
Impedance measurements can be performed by passing a current of known
frequency and amplitude through the battery and measuring the resultant ac
voltage drop across each cell/unit. The ac voltage measurement is taken
between the positive and negative terminals of individual cells or the smallest
group of cells possible. Compute the resultant impedance by Ohm's law.
Conductance measurements(Our Testing Method)
Conductance measurements can be performed by applying a voltage of known
frequency and amplitude across a cell/unit and observing the ac current that
flows in response to it. The conductance is the ratio of the ac current
component that is in-phase with the ac voltage, to the amplitude of the ac
voltage producing it.
The Benefit of Our Test Method
Conductance correlates directly to battery capacity
Passive test method is safe & repeatable
Never discharges the battery
Can Test discharged batteries
