BATTERY INFORMATION
Normal Charging Tips
Self- Examination:1. When charging, orange light twinkles for 1 second and goes out, which means
the charger has passed its self-examination and it can charge the battery normally. If the light
remains orange or the red light twinkles, it means the charger can not pass its self-examination or
charge the battery.
Trickle Pre-Charging:2. If red light twinkles when battery is inserted into the charger, it means the
remnant voltage is low and the charger is trickle-charging the battery (Pre-Charging Status). The
charger will automatically turn into normal charging when the battery reaches a certain electric
quantity, And if the red light stops twinkling, it means the remnant voltage meets a certain electric
quantity, the charger will charge the battery normally.
NOTE: Trickle charging (Pre-Charging Status) time can not beyond 30 minutes. If the indicating
lamp still twinkles after 30-minute trickle-charging, it means that the charger can not charge the
battery. Please check whether the battery or charger is damaged.
