2. Initial Check: The charger will perform a self-check upon power-on. Ensure the screen displays correctly.
3. Optional Car Use: For in-car charging, use the provided 3A car adapter.

6. Operating Instructions

6.1 Inserting Batteries

Carefully insert batteries into the charging slots, ensuring correct polarity (positive and negative terminals align with the markings in the slot). The charger will automatically detect the battery type and begin charging.

6.2 Adjusting Charging Current

The charger offers three charging current options: 0.5A, 1.0A, and 2.0A. Press the 'CURRENT/REFRESH' button to cycle through these options. Selecting the appropriate current helps prolong battery life.

6.3 Capacity Test Mode

To accurately test the real capacity of your batteries, use the 'TEST' mode. In this mode, the charger will fully charge the battery, then discharge it, and finally recharge it, recording the discharged capacity. This process provides a precise measurement of the battery's actual capacity.

6.4 Refresh Mode

For Ni-MH batteries, the 'REFRESH' mode can help eliminate the memory effect. This mode involves a series of charge-discharge cycles to restore the battery's full capacity.
