Included Accessories: The product comes with a power cable, but no power adapter. You can use your phone charger to power the device. The power cable uses a USB connector, and the interface on the battery tester is Micro USB.\u003c\/div\u003e\n\u003cdiv\u003e2. Capacity Measurement Principle: This battery capacity tester measures capacity using the discharge method. Capacity testers based on other principles cannot directly measure actual battery capacity. Discharge testing is the only method for measuring a battery's actual discharge capacity.\u003c\/div\u003e\n\u003cdiv\u003e3. Button Cell Discharge Time: Button cells require a long discharge time, typically tens to over 100 hours. This is a characteristic of the battery, not the tester. If required, the tester supports a maximum discharge current of 20mA. The continuous discharge current of a 2032 battery generally should not exceed 3mA. At this current, the measured capacity may be slightly lower than the battery's rated capacity. This is a characteristic of the battery, not the tester.\u003c\/div\u003e\n\u003cdiv\u003e4. Discharge Modes: The TEC2032 Battery Capacity Tester is designed specifically for measuring button cell capacity and offers two discharge modes: constant current and constant resistance. The constant current mode supports a current range of 0.5-20mA. The constant resistance mode offers three resistor options: 5kΩ, 10kΩ, and 15kΩ.\u003c\/div\u003e\n\u003cdiv\u003e5. Battery Holder Compatibility: The tester comes with a battery holder for 2032 batteries. To test batteries of other shapes or sizes, users can solder on a different battery holder. Additional soldering pads are provided on the tester for expansion.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/div\u003e\n\u003cdiv\u003e* Extended Operating Time: Supports long-duration testing, with a maximum timer duration of 999 hours.\u003c\/div\u003e\n\u003cdiv\u003e* High Measurement Accuracy: Current error: less than 0.4%; voltage error: less than 10mV.\u003c\/div\u003e\n\u003cdiv\u003e* High Capacity and Timing Accuracy: Capacity measurement error is less than 0.4% in constant current mode and less than 1.5% in constant resistance mode. Timing error is less than 1 second per day.\u003c\/div\u003e\n\u003cdiv\u003e* Power-Loss Data Retention and Automatic Resume: If the power supply is accidentally disconnected during testing, the measured capacity and elapsed time are automatically saved. The discharge process is also remembered. When power is restored, the tester automatically resumes discharging, and the capacity and elapsed time continue accumulating from their previous values.\u003c\/div\u003e\n\u003cdiv\u003e* No Computer Connectivity: The TEC2032 Standalone Version does not support computer connectivity. It is designed for testing button cell batteries, which can require long discharge times. If you need computer connectivity, please choose the TEC2032 PRO Version, which also supports standalone operation.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cb\u003eParameter Adjustment and Display:\u003c\/b\u003e\u003c\/div\u003e\n\u003cdiv\u003eThe 4-digit digital display shows the following information:\u003c\/div\u003e\n\u003cdiv\u003e1.
