Product Features
  

         
Car Battery Tester has digital LCD display, easy to read the measurement result. With backlight, it makes easy to read in low light areas. suitable for testing automotive battery tester, lead-acid batteries it can test.
         
Battery Voltage Meter is mainly used to measure battery terminal voltage and internal resistance.There is no limit to the capacity of the battery.
         
Adopt four-wire method which helps to ensure the accuracy of the measured value.To ensure that the test probe is in good contact, and then the surface of the tested battery can not have oxidation phenomenon, or the measured value will be much larger than the actual value.
         
It is applicable for measurement of internal resistances of Lithium-ion, nickel-hydroxide, lithium-manganese cells or assembled battery. Ensure probing steadily on batteries terminals(make sure the + - right).
         
The testing result will be greatly influenced if there is any oxidation problem on the tested battery surface.Battery: 9V battery, 6F22 or equivalent, 1 piece (Not Provided by Seller).
