• The charger supports both AA and AAA batteries in any slot. For AAA batteries, ensure they make proper contact with the smaller terminals.

This image demonstrates how to insert both AA and AAA batteries into the charger's 12 independent slots. It highlights the flexibility of charging different battery types simultaneously.

2. Understanding the LCD Display

• Upon inserting batteries, the LCD screen will display the real-time charging status for each individual slot.
• Battery icons will animate to indicate active charging.
• A full, static battery icon indicates the battery is fully charged.
• An "X" or "Wrong" icon indicates a non-rechargeable, damaged, or incorrectly inserted battery.

This image provides a close-up of the LCD screen, showing battery icons indicating different charge levels (e.g., <33%, <66%, 100%) and a "Wrong" indicator for a detected non-rechargeable battery.

3. Charging Process

• The charger will automatically begin charging once batteries are correctly inserted and power is connected.
• Charging time varies depending on battery capacity and initial charge level.
• The charger uses advanced MCU control and -ΔV function for optimal charging.

4. Discharge Function

• To activate the discharge function, press and hold the "Charge/Discharge Button" (located on the left side of the LCD screen) for approximately 3 seconds.
• The charger will discharge the batteries to eliminate memory effect, then automatically switch to charging mode once the discharge process is complete.
