ZB2L3 18650 Battery Tester External Load Discharge Description
ZB2L3 battery capacity tester with discharge type 1.2-12 V, external charging capacity of 18650 batteries, and other tests. This single-function tool allows for load cutoff control and provides real-time integrated discharge current capacity results. Maximum discharge voltage and current of 15 V and 3 A, self-discharging. Maximum capacity statistics up to 9999 Ah (9999000 mAh). Automatic detection and development of the appropriate battery cutoff voltage, but can also be adjusted manually. Supply voltage: DC 4.5-6 V (Micro-USB port). Operating current: less than 70 mA. Discharge voltage: 1.00-15.00 V, resolution 0.01 V. Termination voltage range: 0.5-11.0 V. Supported current: 3.000 A, resolution 0.001 A. Maximum voltage measurement error: 1% 0.02 V. Maximum current measurement error: 1.5% 0.008 A. Error codes and their meanings: Err1: Battery voltage is above 15 V. Err2: Battery voltage is lower than the termination voltage. Err3: The battery cannot tolerate excessive resistance during charging or discharging of the power cable. Err4: Overcurrent (current exceeds 3.1 A). Note: Use the resistor during the discharge process. Resistor loads heat up considerably, please take care! To improve measurement accuracy, a specially designed DC bias voltage has been developed for this circuit. If the terminal displays a small voltage, this does not affect the actual measurement. If you short-circuit the input terminals (absolute 0 V), 0 will be displayed. Instructions: 1. For the first test, the battery should be fully charged. 2. Connect the positive terminal of the battery under test to the positive terminal and the negative terminal to the negative terminal. Do not reverse the connections (reversing the connections can damage the circuit)! The load is connected to the positive and negative outputs and powered via the tester's micro-USB power supply (USB power supply for desktop or laptop). The battery voltage is then displayed.
3. To start the test, simply press the "OK" button. The tester automatically generates a suitable final voltage for the battery's full charge voltage and will flash three times after the test. An artificial final voltage only needs to be generated if the battery voltage display shows the "P" status. By pressing the "+" or "-" buttons, you can change the final voltage display, which begins with P. The representative voltage resolution is 0.1 V. After pressing "OK," the test can be started.
4. After the test starts, the electronic switch for controlling the tester's load is turned on. This displays the release capacity (Ah) between the wheels, the current discharge current (A), and the battery voltage (V). When the battery voltage reaches the set cutoff voltage, the load control switches off the tester display data. The capacity data remains at (Ah) and above, and the corresponding indicator flashes rapidly. Now the actual battery capacity is displayed. The discharge capacity display is ended by pressing "OK". The flashing ensures a stable data display. Pressing the "OK" button again returns the device to the powered-on state. The battery test section can be easily replaced.
