• Battery charging should be performed under ambient temperatures within the guaranteed operating range of
0 to 40°C (32 to 104°F).
• Charging will stop if the ambient temperature is outside the chargeable temperature range (below 0°C or
above 40°C).
• When charging in an environment of 35°C or higher, the charging time may be extended because the internal
temperature rise is detected and charging is stopped and started repeatedly.
• If the battery is not fully charged after approximately 5 hours of charging, it is assumed that the battery is
faulty and the Charge LED will flash. The battery cannot be used and should be replaced with another
battery.
