• Car/Truck Mode: Standard charging for automotive batteries.
• AGM/GEL Mode: Optimized charging for AGM and Gel batteries.
• Motorcycle Mode: Suitable for smaller motorcycle batteries.
• Repair Mode: Activates pulse repair technology for sulfated or stratified batteries. (Note: Cannot repair totally dead batteries).
• Winter/Summer Mode: Automatic temperature compensation adjusts charging based on environmental conditions.

5.2 Display Content

The digital display provides real-time information:

• Real-time Temperature: Shows the ambient temperature.
• Real-time Voltage: Displays the current battery voltage.
• Real-time Current: Indicates the charging current in Amps.
• Charging Status: Battery icon shows charge level.
• Error Indicators: "Erro" for errors, "OFF" for power off, "FUL" for fully charged, "PUL" for pulse repair, "SUP" for supply mode.
