Cautions concerning use and storage
of the rechargeable Li-ion battery
pack
• Do not use the battery with the outer
covering or label removed, as doing so may
result in malfunction.
• Temperature when using: 5 to 35°C
(41 to 95°F)
• Temperature when charging: 5 to 35°C
(41 to 95°F)
• Do not use the battery pack near fire
or inside a car exposed to the hot sun,
etc. (Locations in which the temperature
reaches 60°C [140°F] or higher.)
• At high temperatures, the safety mechanisms
and protective devices inside the battery
pack may be damaged, causing an abnormal
chemical reaction to occur, or causing the
battery pack to catch fire, explode, leak or
spew battery fluid, or generate heat. If the
safety mechanisms and protective devices
are damaged, the battery pack will become
unusable.
An environment with extremely high or low
temperatures will cause the battery capacity to
deteriorate and shorten the usable time, and
may even shorten the battery life.
• Avoid storing the battery pack with it near full
charge. It is recommended to store the battery
pack when it is near fully discharged.
• If the battery pack is completely discharged, it
may become unable to be recharged again. To
avoid this, charge the battery pack for at least
five minutes every six months.

• Storage temperature: 5 to 35°C
(41 to 95°F)
When not using the battery pack, remove it
from the unit and store at 5 to 35°C (41 to
95°F) in a place with no condensation.
Do not keep in a place where the temperature
reaches 45°C (113°F) or higher.
• Humidity: 10 to 90% (no condensation)
• Depending on the usage environment, the
Li-ion battery pack may expand as it nears the
end of its battery life. This is a characteristic of
Li-ion batteries and does not pose a hazard.
• Li-ion batteries are consumable products. As
you continue to use and recharge the battery
pack, the amount of time until the battery pack
discharges will gradually shorten. When a fully
charged battery pack discharges in less than
half the time as at the time of purchase, the
battery pack is nearing the end of its battery
life. We recommend replacing the battery pack
as soon as possible in such cases.
