2. Safety Precautions
- Read this instruction manual thoroughly before operating the device.
- This device is intended for indoor use only.
- Do not attempt to test batteries that are visibly damaged or leaking.
- Ensure correct polarity when connecting batteries to avoid damage to the tester or battery.
- Keep the device away from moisture, extreme temperatures, and direct sunlight.
- Do not disassemble or modify the tester. Refer all servicing to qualified personnel.
3. Setup
3.1 Powering the Device
The Dlyfull B3 is powered by two LR03 (AAA) batteries. To install or replace batteries:
- Locate the battery compartment on the back of the tester.
- Open the battery compartment cover.
- Insert two LR03 (AAA) batteries, ensuring correct polarity (+/-).
- Close the battery compartment cover securely.
3.2 Initial Check
Upon successful battery installation, the LCD display should illuminate, indicating the device is ready for use.
4. Operating Instructions
The Dlyfull B3 allows you to test battery voltage, capacity percentage, and internal resistance.
4.1 Selecting Battery Type
Before testing, turn the central rotary dial to select the appropriate voltage and type for the battery you intend to test. The dial has markings for various battery chemistries and voltages (e.g., 1.2V Ni-MH/CD, 1.5V Alkaline, 3.7V Li-ion, 9.0V Alkaline, etc.).
4.2 Connecting the Battery
Use the integrated test probes (red for positive, black for negative) to connect to the battery terminals. Ensure a firm and stable connection for accurate readings.
Figure 2: Steps for checking battery health.
4.3 Interpreting Readings
Once connected, the LCD display will show:
- Voltage (V): The current voltage of the battery.
- Internal Resistance (mΩ): An indicator of the battery's health and ability to deliver current. Lower values generally indicate a healthier battery.
- Capacity Percentage (%): A bar graph and numerical percentage indicating the estimated remaining capacity.
The tester also features a self-detection function to assist in identifying battery status.

6. Maintenance
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the tester in a cool, dry place when not in use. If storing for extended periods, remove the LR03 batteries to prevent leakage.
- Battery Replacement: Replace the internal LR03 batteries when the display becomes dim or the device fails to power on.
7. Troubleshooting
- No Display: Check if the internal LR03 batteries are correctly installed and have sufficient charge. Replace if necessary.
- Inaccurate Readings: Ensure the rotary dial is set to the correct battery type and voltage. Verify that the test probes have good contact with the battery terminals. Clean probes if corroded.
- Device Not Responding: Remove and reinsert the internal LR03 batteries. If the issue persists, contact customer support.
