Nickel Metal Hydride Battery
3.3 Charging
Please read the following instructions thoroughly before charging a battery.
n
Charging location
A battery can be charged as long as its temperature range is between 0°C and 40°C. However, to ensure the life
of the battery, the following conditions are recommended.
• Indoors, in a cool, well ventilated place.
• Where the temperature can be kept between 10°C to 25°C while charging.
• A level and stable location.
CAUTION
Avoid charging in the following places.
Example 1: High-temperature locations exposed to direct sunlight or near a stove. In cold regions,
where the temperature drops to below zero.
*Charging will not start when the battery temperature is too high or too low.
Example 2: Outdoor locations exposed to rainfall or near a sink where the battery may get wet.
*This may cause equipment failure or electric shock due to a short circuit.
Example 3: Within reach of children or pets.
*May cause injury or damage to the equipment.
CAUTION
Do not place any objects on or around the charger while charging, as this may cause the charger to overheat and
adversely affect its performance.
n
Use of specified equipment
WARNING
Use only the specified charger to charge the battery. Failure to do so may cause a fire or damage to the battery.
n
Operating temperature
• To protect the battery, the charger will not start charging if the battery temperature is not within the 0°C to 40°C
range. The charge lamp (green) will continue to flash until the battery reaches an appropriate temperature.
When the battery reaches an appropriate temperature, the charge lamp will light and charging will start
automatically. (The length of the standby time varies with the conditions.)
• After the refresh charging (discharging) of the battery is completed, the charger may go into the charge standby
mode, causing the green lamp to flash. Once the battery reaches an appropriate temperature, this lamp will
light and charging will start automatically.
• The battery temperature increases during charging. However, the charger will be forced to stop charging if the
battery temperature exceeds 50°C. Since charging has not ended normally, it is necessary to charge again after
the battery temperature has decreased.
• Charging a battery immediately after travel or charging a new battery is likely to cause its temperature to
increase, which forces the charger to stop charging. Since charging has not ended normally, it is necessary to
charge again after the battery temperature has decreased.
n
Handling
WARNING
Do not drop or apply a sharp impact to the battery or charger, as it may cause a malfunction.
