Normal Charging Tips
a.
Self-Test:
When powering on the charger, the red light turns on and then
turns off and stays off, which means the charger has passed it self- test
and it is ready to charge the battery. If the light remains orange or the
red light blinks, it means the charger cannot pass it self-test and cannot
charge the battery.
b.
Trickle Pre-Charging:
If red light blinks when the battery is inserted
into the charger, it means that the battery voltage is low and the charger
is trickle-charging the battery (Pre-Charging Mode). The charger will
automatically turn into normal charging when the battery reaches a
certain electric charge, and if the red light stops blinking, it means the
battery voltage has reached a certain level, and the charger will charge
the battery in normal mode.
