Product size: 110×88x30mmTest 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 stabilizesAbout 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 stageThis 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.Specification: Package Weight One Package Weight 0.12kgs / 0.27lb One Package Size 16cm * 11cm * 5cm / 6.3inch * 4.33inch * 1.97inch Qty per Carton 54 Carton Weight 7.60kgs / 16.75lb Carton Size 50cm * 35cm * 32cm / 19.69inch * 13.78inch * 12.6inch Loading Container 20GP: 476 cartons * 54 pcs = 25704 pcs40HQ: 1105 cartons * 54 pcs = 59670 pcs

1. Four operation modes: constant current operation; constant voltage operation; constant power operation; constant resistance operation2. This time, a flexible input wiring port design is adopted. Users can manually connect different adapters to achieve different measurement functions to extend the functions3. Automatically generate measurement data reports, stop voltage and time-limited discharge4. First turn off the load switch "OFF", measure the current battery no-load voltage, and then turn on the load switch "ON" through the setting key. At this time, you can read the internal resistance parameters of the current battery. The internal resistance of this table is calculated by the formula: (no-load voltage-load voltage)/current current=battery internal resistance5. Long press the setting key, and then short press the setting key when it flashes to switch to time-limited discharge for timing setting to obtain the effect of worry-free discharge aging. The time-limited discharge can be set to count down for any length of 1-99 hours and 59 minutes. When the set time is reached, the discharge will automatically stop.
