The inverter is installed on the car, will it affect the results?All inverters will affect the test results of the meter, so please remove the inverter before measuring to ensure the correctness of the test.2. Can this product accurately predict when the battery will fail?The internal resistance of sealed lead acid batteries is complex, which includes the ohmic internal resistance of the battery, the internal resistance of the concentration difference polarization, the internal resistance of the electrochemical , and the interference effect of the double layer capacitor charging. The components and their relative contents contained in the internal resistance values measured by different test methods and at different times are different, so the measured internal resistance values are also different. There is no strict mathematical relationship between the internal resistance (or conductance) and battery capacity of sealed lead acid batteries, and the battery life cannot be predicted based on the internal resistance (or conductance) value of a single battery. However, when the

High Performance: The internal use of accurate circuits and powerful digital processing units, using four wire Kelvin test connection method to complete a series of complex data collection and calculation, each test result is obtained.

Large Screen LCD Display: The instrument is well designed, easy to operate, accurate in reading, and fully functional. The instrument adopts a large screen LCD display, and the test process and results are displayed on one screen.

Input Protection: In addition, the input protection is strengthened inside the instrument, with protection measures to prevent reverse polarity, prevent voltage connection from being too high, and poor contact of the test chuck, so as to be safer, more co

Multipurpose: The instrument can be used in the production and sales of batteries, auto parts maintenance and other equipment using lead acid batteries. It is an analysis and testing tool for the performance status of lead acid batteries.

Battery Testing Tool: This instrument is a performance analysis and testing tool for 12V 24V lead acid batteries, which can test and analyze the performance of the battery during vehicle startup, generator charging, and static state.
