The *-stage mode charging
:
First stage ( constant current ) : The
charger will supply constant current for the
battery
Second stage ( constant voltage )
: The voltage will be rising under the first stage, when it
reach constant voltage value, it will turn into the second
stage. The current will be slowly smaller until it reduce to
floating value,the CV stage will end.
Third stage ( Floating charging ) : When
the current is approaching the value of transition, the
charger will cut down to the given current gradually,
that means the battery power is full and indicator
light turn to green. At this moment, the battery can be
stopped charging or keep on trickle current charging for half
an hour.
