1. المقدمة
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. معلومات السلامة
- 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.
- لا تقم بتقصير أطراف البطارية.
- Operate the device in a well-ventilated area, especially when discharging batteries, as they can generate heat.
- احفظ الجهاز بعيداً عن الرطوبة ودرجات الحرارة القصوى.
- هذا الجهاز ليس لعبة. يحفظ بعيدا عن متناول الأطفال.

5. الإعداد
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.
- توصيل التيار الكهربائي: 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.
- توصيل البطارية: 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.
مهم: 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. تعليمات التشغيل
Follow these steps to perform a battery capacity test:
Figure 2: ZB2L3 Battery Capacity Tester showing the 'OK', '+', and '-' buttons for operation.
- العرض الأولي: After connecting the power and battery, the tester will display the battery's current voltage.
- Set Termination Voltage:
- 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 voltagهـ. هذا هو المجلدtage 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.
- Test Completion: 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 نتائج: 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. الصيانة
- تنظيف: استخدم قطعة قماش ناعمة وجافة لتنظيف الجهاز. لا تستخدم المنظفات السائلة أو المذيبات.
- تخزين: يُحفظ جهاز الاختبار في مكان بارد وجاف بعيداً عن أشعة الشمس المباشرة ودرجات الحرارة القصوى.
- تقتيش: Periodically check the terminals and connections for any signs of wear or damage.
8. استكشاف الأخطاء وإصلاحها
| مشكلة | السبب المحتمل | حل |
|---|---|---|
| الشاشة لا تضيء. | No power or incorrect power supply. | 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. | Verify the termination voltage 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. |
