Troubleshooting
If you encounter issues with your Dlyfull battery testers, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Tester does not power on (B4) | Dead or incorrectly inserted internal AAA batteries. | Replace AAA batteries, ensuring correct polarity. |
| Tester does not power on (DB1) | Internal battery is depleted. | Charge the DB1 via USB-C cable. |
| Inaccurate readings | Poor contact with battery terminals; incorrect battery type selected (B3); dirty contacts. | Ensure firm contact. Verify battery type selection. Clean contacts with a dry cloth. |
| Display is dim or flickering | Low internal battery (B4, DB1). | Replace AAA batteries (B4) or recharge (DB1). |
| B2 shows "Poor" for new battery | Battery is genuinely low; B2 is not for rechargeable batteries. | Try a different new battery. Ensure you are not testing a rechargeable battery with B2. |
