Test method:
Wait a few seconds after installing the battery, read the battery data, and the battery voltage and internal resistance parameters will be displayed. There will be a delay in data loading during the battery loading and unloading process. Check after the data stabilizes
About capacity test:
The discharge must be completed to measure the capacity. I have never met anyone who wants to measure the capacity just by installing the battery. Discharge takes time. You have to wait for the discharge to end automatically to have a complete capacity in the discharge stage
This product uses the DC two-wire method to test the battery internal resistance principle:
DC impedance is based on the physical formula R=V/I, the test set The battery is forced to pass a large constant DC current (currently 10A-80A is generally used) in a short period of time (usually 2-3 seconds), and the voltage at both ends of the battery is measured, and the current battery internal resistance is calculated according to the formula. The DC two-wire test internal resistance is the result of the middle line resistance, and the result is used for reference comparison between batteries tested in the same batch. Due to the influence of contact resistance and battery self-loss, the internal resistance may not be identified normally and cannot be measured. For those with high requirements for internal resistance measurement accuracy, the TS235 internal resistance tester (AC four-wire method) can be used for internal resistance testing.
