1. はじめに
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. 安全情報
- 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.
- バッテリー端子をショートさせないでください。
- Operate the device in a well-ventilated area, especially when discharging batteries, as they can generate heat.
- デバイスを湿気や極端な温度から遠ざけてください。
- このデバイスはおもちゃではありません。 小児の手の届かない場所に保管。

5. セットアップ
Before operating the ZB2L3 tester, ensure all connections are made correctly.
Figure 1: ZB2L3 Battery Capacity Tester showing the micro USB power input, battery terminals, and load terminals.
- 電源接続: 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.
- バッテリー接続: 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.
重要： 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. 操作手順
Follow these steps to perform a battery capacity test:
Figure 2: ZB2L3 Battery Capacity Tester showing the 'OK', '+', and '-' buttons for operation.
- 初期表示: After connecting the power and battery, the tester will display the battery's current voltage.
- 終了ボリュームの設定tage:
- 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. これは巻ですtage 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.
- テスト完了: The test will automatically stop when the battery voltage reaches the set termination voltage. The display will then show the final accumulated capacity (Ah) and flash.
- View 結果： 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. メンテナンス
- クリーニング： デバイスの清掃には、柔らかく乾いた布をご使用ください。液体クリーナーや溶剤は使用しないでください。
- ストレージ： テスターは直射日光や極端な温度を避け、涼しく乾燥した場所に保管してください。
- 検査： Periodically check the terminals and connections for any signs of wear or damage.
8。 トラブルシューティング
| 問題 | 考えられる原因 | 解決 |
|---|---|---|
| ディスプレイが点灯しない。 | 電源が入っていないか、電源が正しくありません。 | 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. | 終了ボリュームを確認するtage 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. |
