3-1. Power-down memory function: the product remembers the current charging mode
after power outage, and restores the original state when the grid resumes; the maximum
time is 12h with battery connection.
In this mode, the Power LED is on, ant the backlight on the LCD display is off.
3-2. Charging mode: identify 6V/12V batteries automatically; for 6V batteries, only
6V/1A SLOW mode is available; for 12V batteries, three charging modes are available, as
follows:
• 6V 1A /SLOW charging mode (default)
• 12V 1A /SLOW charging mode
• 12V 4A /FAST charging mode
• 12V 4A /LOW TEMP charging mode (Environment temperature <10°C)
The minimum voltages for automatic identification of 6V and 12V batteries are 3V and
7.4V respectively.
3-3. Protection:
• Short circuit protection
• Reverse polarity protection: the LCD displays reverse polarity signal
• Overheating protection
3-4. LCD display function
The LCD displays battery status, charging mode, charging state, real-time voltage, and
error message, and integrates LED indicators.
