mode. LCD flashes the real time battery voltage at 1Hz frequency and the battery
icon scrolls. Press the button to pause/resume the charging process. The battery
icon stops scrolling when it is "pause".
After charging the battery by 2 minutes, if battery voltage is still <4.5V, LCD flash at 1Hz
frequency to display "Lo" and "real time voltage" alternatively. Red LED light keeps "ON"
ii) 12V: When the battery voltage is between 7.4V and 10V. The charger will work at 12V/
Slow mode. Press the button and change the mode to "Fast", "Low Temp" or "Pause" the
charging process respectively. The battery icon stops scrolling when it is "pause".

In these 2 cases, please press the button to detect/check the battery status and start
the charging process again. Don't need to disconnect the AC power and battery
cable clamp.
Keep charging the battery 4 hours (6V mode)/9 hours (12V mode). If the battery voltage
