5.1 Using the DLYFULL B1T Battery Tester
The B1T tester is designed for simple, two-step operation:
- Sartu bateria: Place the battery into the appropriate slot, ensuring correct polarity. For 1.5V cylindrical batteries (AAA, AA, C, D), use the sliding arm. The magnetic hold will secure the battery. For 9V batteries, connect the terminals to the designated contacts at the top. For button cells, place them in the small slot on the side.
- Read Result: Observe the analog needle on the display. It will point to 'Good' (green), 'Low' (yellow), or 'Replace' (red) to indicate the battery's health.

Image: A visual guide showing the two simple steps for using the DLYFULL B1T Battery Tester: 1. Press and Pull the slider to insert the battery, and 2. Read the test result on the gauge.
Testing 9V Batteries with B1T:
To test a 9V battery, align its positive and negative terminals with the corresponding contacts at the top of the B1T tester. The needle will then indicate the battery's status.

Interpreting B1T Results:
- Green ('Good'): The battery has sufficient power for use.
- Yellow ('Low'): The battery is partially discharged and may need replacement soon, or might not power high-drain devices.
- Red ('Replace'): The battery is depleted and should be replaced.

5.2 Using the DLYFULL B2-Blue Battery Tester
The B2-Blue tester features multiple slots and contacts for different battery types. Ensure the battery is inserted correctly according to its size and polarity.
- Sartu bateria: Place the battery into the appropriate testing slot or connect it to the designated contacts. For cylindrical batteries (AA, AAA, C, D, CR123A, CR2, N, CRV3, 2CR5, CR-P2), use the main slots. For 9V batteries, use the dedicated 9V contacts. For button cells, place them in the specific button cell testing area.
- Read Result: The LCD screen will display the battery's voltage and indicate its health status as 'Poor', 'Weak', or 'Good'.

Interpreting B2-Blue Results:
- Ona: The battery has sufficient voltage eta edukiera.
- Weak: The battery's voltage or capacity is reduced; it may not perform optimally in all devices.
- Txarra: The battery is significantly discharged or faulty and should be replaced.
6. Mantentzea
- Garbiketa: Wipe the testers with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Biltegiratzea: Store the testers in a cool, dry place, away from direct sunlight and extreme temperatures.
- Bateria kentzea: Always remove batteries from the tester after use.
7. Arazoak
- No Reading (B1T): Ensure the battery is making firm contact with the terminals and polarity is correct. The magnetic hold should assist with 1.5V cylindrical batteries.
- No Reading (B2-Blue LCD): Check battery insertion and polarity. If the battery is completely dead, the tester may not power on to display a reading.
- Irakurketa okerrak: Ensure the battery terminals are clean and free of corrosion. Test the battery again. If issues persist, the tester may be faulty.
- Battery Falls Out (B1T): For 1.5V cylindrical batteries, ensure the magnetic hold is engaged. For 9V batteries, hold them firmly against the contacts during testing.
