Rakstore ZB2L3 Battery Capacity Tester User Manual

1. ບົດແນະນຳ

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.

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

1. ການເຊື່ອມຕໍ່ການສະຫນອງພະລັງງານ: 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. ການເຊື່ອມຕໍ່ຫມໍ້ໄຟ: 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.

ສຳຄັນ: 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.

   • 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. ນີ້ແມ່ນ 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.
