1. 서론
The Rakstore ZB2L3 Battery Capacity Tester is a versatile device designed to measure the capacity of various battery types, including 18650 Lithium batteries and Lead-Acid batteries. It functions as a discharge tester, allowing users to determine the actual capacity by discharging the battery through a load and measuring the discharged energy. This manual provides detailed instructions for the safe and effective use of the ZB2L3 tester.
2. 안전 정보
- Always ensure correct polarity when connecting batteries to avoid damage to the tester and battery.
- Use appropriate discharge loads. Overloading the tester or using incorrect loads can cause overheating and damage.

5. 설정
Before operating the ZB2L3 tester, ensure all connections are made correctly.

- 전원 공급 장치 연결: Connect a DC 4.5-6V power source to the micro USB port on the tester. A standard phone charger or power bank can be used. The display should light up.
- 배터리 연결: Connect the battery to be tested to the "BAT+" and "BAT-" terminals. Ensure correct polarity. The tester will display the current battery voltage.
- Discharge Load Connection: Connect an appropriate discharge resistor (load) to the "LOAD+" and "LOAD-" terminals. The resistance value of the load will determine the discharge current. Ensure the load can handle the expected power dissipation.
중요한: The discharge current should not exceed 3.000A. Calculate the required resistance using Ohm's Law (R = V/I) and Power Law (P = V*I or P = I²*R) to ensure the resistor can handle the power. For example, if testing a 3.7V battery at 1A, you need a 3.7 Ohm resistor capable of dissipating at least 3.7W.
6. 사용 설명서
Follow these steps to perform a battery capacity test:

- 초기 표시: After connecting the power and battery, the tester will display the battery's current voltage.
- 설정 종료 볼륨tage:
- Press the "OK" button once. The display will show the current termination voltage (e.g., "U 3.00").
- Use the "+" and "-" buttons to adjust the termination voltage. 이것은 볼륨입니다tage at which the discharge test will stop. For 18650 Lithium batteries, a common termination voltage is 3.0V. For Lead-Acid batteries, consult the battery's specifications.
- Press "OK" again to confirm the setting and return to the main display.
- Start Discharge Test:
- With the battery and load connected, and the termination voltage set, press and hold the "OK" button for approximately 3 seconds.
- The tester will begin discharging the battery through the connected load. The display will cycle through current voltage (V), discharge current (A), and accumulated capacity (Ah).
- Monitor Test Progress: Observe the display. The voltage will gradually decrease, and the accumulated capacity will increase.
- 테스트 완료: The test will automatically stop when the battery voltage는 설정된 종료 볼륨에 도달합니다.tage. The display will then show the final accumulated capacity (Ah) and flash.
- View 결과: After the test stops, you can press the "OK" button to cycle through the final voltage, current, and capacity readings.
- Reset for New Test: To start a new test, disconnect the battery and load, then reconnect them, or simply press and hold the "OK" button again to clear the previous results and start a new cycle.
7. 유지관리
- 청소: 부드럽고 마른 천으로 기기를 닦으십시오. 액체 세척제나 용제를 사용하지 마십시오.
- 저장: 테스터는 직사광선과 극한 온도 변화를 피해 서늘하고 건조한 곳에 보관하십시오.
- 점검: Periodically check the terminals and connections for any signs of wear or damage.
8. 문제 해결
| 문제 | 가능한 원인 | 해결책 |
|---|---|---|
| 디스플레이가 켜지지 않습니다. | 전원이 공급되지 않거나 전원 공급에 문제가 있습니다. | Ensure micro USB power supply is connected and providing DC 4.5-6V. Check cable and adapter. |
| Test does not start. | Battery not connected, load not connected, or "OK" button not held long enough. | Verify battery and load connections. Hold "OK" button for 3 seconds to initiate. |
| Incorrect capacity reading. | Incorrect termination voltage set, or load resistance is too high/low. | 종료 볼륨을 확인하십시오tage setting. Ensure the discharge load is appropriate for the desired current. |
| Tester gets hot during operation. | High discharge current or insufficient ventilation. | Ensure the discharge current does not exceed 3.000A. Operate in a well-ventilated area. The discharge load resistor will also generate heat; ensure it is rated for the power. |
