5.2. Charging Process
To begin charging, simply insert your rechargeable battery into one of the four independent charging bays. Ensure the positive (+) and negative (-) terminals of the battery align correctly with the charger's markings. The charger will automatically detect the battery type (Li-ion, LiFePO4, Ni-MH/Ni-Cd) and initiate the appropriate charging mode. The LCD display will show real-time charging information.

5.3. Adjusting Charging Speed
Each of the four independent bays allows you to select the charging current. You can choose from 250mA, 500mA, 800mA, 1000mA, or up to 1999mA. To adjust the current for a specific slot, short press the "SLOT" button to select the desired channel, then press the "MODE" button to cycle through the available current options. The 1999mA fast charging option is specifically suited for lithium batteries in the C1 channel when no battery is present in the C2 channel.

5.4. Smart LCD Display
The integrated LCD display provides comprehensive real-time information for each charging channel. You can view the current charging condition, real-time voltage, optional charging speed, battery type, discharge mode, and discharge time/capacity. Short press the "SLOT" button to switch between viewing the corresponding information for channels C1, C2, C3, and C4.
