the charger LED will light red to indicate that the
battery is charging rapidly. When the battery is
90% charged, the LED will begin to blink green to
indicate that the battery is trickle charging. When
the battery is fully charged, the LED will change to
a steady green light to indicate that the battery is
fully charged.
Note: Even though new batteries might prematurely
indicate a full charge (steady green LED), charge
the battery for 14 to 16 hours prior to initial use for
best performance.
Batteries will charge best at room temperature.
