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 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 acid batteries, and the battery life cannot be predicted based on the internal resistance (or conductance) value of a single battery. However, when the
