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 -5°C and +45°C. However, to ensure the life
of the battery, the following conditions are recommended.
• Indoors, in a cool, well ventilated place.
• 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 -5°C to +45
°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.)
• Even when the charger is charging, it could go into the charge standby mode due to changes in the
environment, and cause the green lamp to flash.
• If the charge standby mode, wherein the green lamp flashes slowly, continues for a long period of time, the
flashing of the lamp changes to a faster pace, and the charger automatically stops the charge standby mode.
You may retry charging by moving to another location with an appropriate temperature.

Handling
WARNING
Do not drop or apply a sharp impact to the battery or charger, as it may cause a malfunction.
