6. Operating Instructions

Follow these steps to test your batteries:

1. Identify Battery Type: Locate the appropriate slot or contact points on the tester for your battery type (e.g., D, C, AA, AAA, 9V, Button Cell, 14500, 10440, 16340, CR2032).
2. Observe Polarity: Pay close attention to the positive (+) and negative (-) markings on both the battery and the tester. Ensure the positive electrode of the battery aligns with the positive contact point on the tester, and the negative electrode with the negative contact point. For 9V batteries, the two measuring points are located at the bottom of the unit.
3. Insert Battery: Gently place the battery into its designated slot or press it against the contact points.
4. Read Display: The battery's voltage reading will be shown on the LCD display.

6.1 Testing Examples:

7. Battery Types and Readings

The BT189 can measure a variety of battery types within a range of 1.2V to 4.8V. The LCD display will show the voltage, indicating the battery's charge level.

Note: The parameters in this table are for reference only; actual measurements may vary.

8. User Tips

• Check Battery Contacts: If the LCD display shows no value, first ensure that the battery is making proper contact with both the positive and negative terminals of the tester. If contact is good and still no reading, the battery is likely completely dead.
• Wide Compatibility: The BT189 is suitable for a broad range of batteries, including 3.2V batteries (e.g., 3.2V 700mAh) as its measurement range extends from 1.2V to 4.8V.
• Self-Powered: Remember that the tester draws power from the battery being measured, so no external power or additional batteries are needed for the tester itself.

9. Maintenance

• Cleaning: Use a soft, dry cloth to clean the tester. Do not use abrasive cleaners or solvents.
• Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures. If not using for long periods, ensure no battery is left in the tester to prevent potential damage.
• Material: The tester is made of ABS insulating plastic, providing durability and insulation.

10. Troubleshooting

Problem: LCD display shows no reading.

Solution:

1. Ensure the battery is correctly positioned and making firm contact with the tester's positive and negative electrodes.

2. The battery may be completely dead. The tester will not display a voltage if the battery has no power.

Problem: Inaccurate voltage readings.

Solution:

1. Verify that the battery terminals and the tester's contact points are clean and free of corrosion.

2. Double-check that the battery type matches the selected contact area on the tester.

3. Ensure correct polarity. Incorrect polarity can lead to no reading or incorrect readings.
