Rakstore ZB2L3 Battery Capacity Tester User Manual

1. Introducció

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. Informació de seguretat

• 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.
• No curtcircuiteu els terminals de la bateria.
• Operate the device in a well-ventilated area, especially when discharging batteries, as they can generate heat.
• Mantingueu el dispositiu allunyat de la humitat i de les temperatures extremes.
• Aquest dispositiu no és una joguina. Mantenir fora de l'abast dels nens.

5. Configuració

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

1. Connexió d'alimentació: 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.
2. Connexió de la bateria: Connect the battery to be tested to the "BAT+" and "BAT-" terminals. Ensure correct polarity. The tester will display the current battery voltage.
3. 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.

Important: 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. Instruccions de funcionament

Follow these steps to perform a battery capacity test:

1. Pantalla inicial: After connecting the power and battery, the tester will display the battery's current voltage.
2. 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 voltage. This is the voltage 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.
3. 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).
4. Monitor Test Progress: Observe the display. The voltage will gradually decrease, and the accumulated capacity will increase.
5. 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.
6. View Resultats: After the test stops, you can press the "OK" button to cycle through the final voltage, current, and capacity readings.
7. 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. Manteniment

• Neteja: Feu servir un drap suau i sec per netejar el dispositiu. No utilitzeu netejadors líquids ni dissolvents.
• Emmagatzematge: Guardeu el provador en un lloc fresc i sec, allunyat de la llum solar directa i de temperatures extremes.
• Inspecció: Periodically check the terminals and connections for any signs of wear or damage.
