Charging Prompt
1. Self-examination: When charging, ORANGE light twinkles for 1 second
and goes out. That 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, which means the charger can not pass its self-examination
or charge the battery.
2. Trickle pre-charging: When the battery has been inserted into the charger
and red light twinkles (it means the remnant voltage is low), the charger
trickle charges the battery (pre-charging status), until the battery reaches
a certain electric quantity, the charger automatically turns into normal
charging. 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:The time for Trickle pre-charging does not exceed 30m. After 30m, if
the red indicator is still twinkling, it means it is unable to charge battery. Please
kindly check battery and charger.
