Once batteries are inserted, the charger will automatically detect their type and initiate charging. The LCD will display real-time information for each channel.

6.2 Compreendendo o visor LCD

The LCD screen provides detailed information for each of the four channels:

• Volumetage (v): Volume atual da bateriatage.
• Atual (A): Real-time charging current.
• IR (mΩ): Internal Resistance of the battery.
• Cap (mAh/Wh): Accumulated charging capacity or energy.
• Tipo de Bateria: Indicates Li-ion or Ni-MH.

6.3 Changing Charging Current

Press the 'Curr.' button to cycle through available charging currents (0.25A, 0.5A, 1A, 2A, 3A). The charger can deliver a maximum of 3A to a single slot, 2A to two slots simultaneously, or 1A to all four slots.

6.4 Modos de operação

Press the 'Mode' button to switch between the three operation modes:

• Modo de carregamento: Standard charging of batteries.
• Grading Mode: Tests the real capacity of batteries by fully charging, discharging, and then recharging them. The final charge capacity is displayed.
• Storing Mode: Charges or discharges Li-ion batteries to their optimal storage voltage (typically 3.7V-3.8V) to maximize lifespan when not in use.
