3. HOW TO CHARGE YOUR BATTERY
CHARGING PROCEDURE
1) Plug the charger into an appropriate outlet.
2) Slide the battery pack into the charger, the LIGHT
will become green and flash to show charging has
started.
3) After charging approx. 45 minutes, the light will stay
green without flashing, which means the battery is
full, and charging is completed.
WARNING:
When battery charge runs out after
continuous use or exposure to direct sunlight
or heat, allow time for the battery to cool down
before re-charging to achieve the full charge.
CHARGING INDICATOR
This charger is designed to detect some problems that
can arise with battery packs. Indicator lights indicate
problems (see table below). If this occurs, insert a new
battery pack to determine if the charger is OK. If the
new battery charges correctly, then the original pack is
defective and should be returned to a service center or
recycling service center. If the new battery pack displays
the same problem as the original Battery Pack, have the
charger tested at an authorized service center.

BATTERY TEMPERATURE PROTECTION
This charger has a battery temperature protection feature.
When the charger detects a battery pack that is too hot
or cold (the light will be red and flash), it automatically
activates the protection circuit, and suspends charging
until the battery pack has reached the correct temperature.
The charging process will then automatically begin
(the light will be green and flash). This feature ensures
maximum battery life.
DEFECTIVE BATTERY PACKS
This charger will detect a defective battery pack. When
a defective battery pack is inserted into the charger, the
charger will try to repair it. This process will last about
30mins (the light will be green and flash). If the repair is
successful, the charger will automatically begin to charge
the battery pack to the highest capacity possible (the light
will be green and flash). If the light becomes solid red, the
battery pack is dead.
NOTE:
Repaired battery packs are still usable but should
not be expected to perform as much work as new battery
packs.
IMPORTANT CHARGING

for sometime, please recharge the battery before use.
If you want to store the battery for a long time, please
fully charge the battery pack to ensure maximum
battery life.

pack in air temperatures below 0°C, or above 40°C.
This is important as it can prevent serious damage to
the battery pack.

pack and charger to an authorized service center.
f. Under certain conditions, when the charger is plugged
into the power supply, the exposed charging contacts
inside the charger can be shorted by foreign material.
Foreign materials of a conductive nature such as
metallic particles should be kept away from charger
cavities. Always unplug the charger from the power
supply when there is no battery pack in the charger or
before attempting to clean.
