(1)Operating Precautions

Lithium-ion Battery Pack
(A)
Each lithium-ion battery pack has its life. The life span heavily depends on how the battery pack is charged or stored, and it may cause
deterioration of the battery pack to shorten the life span if it is handled improperly. After charging the battery pack, if the performance of the
battery pack does not show any recovery, it is a sign of ending the life. Replace it with a new battery pack. Note the tips below to make the
battery pack last long.
— Be sure to charge the battery pack before using it if the battery pack is used for the first time or if it has not been used for a long period of
time. When charging the battery pack, continue charging until the charge LED lights green (fully charged).
— If the battery pack is repeatedly charged, the life span becomes short. To avoid the repetition of charging the battery pack, be sure that
the remaining capacity is low before you start charging.
— Be sure to charge the battery pack in recommended temperature range. The temperature range is dependant on device you use to charge
Including battery chargers and terminals. Refer to the respective user guides. Charging the battery pack in a temperature outside of the
recommended range cause deterioration.
— When used at low temperatures, the battery pack has a reduced capacity and will supply power for shorter time. The life span of the
battery pack is also shortened.
— Charging the battery pack while the battery pack itself is freeze including inside causes deterioration. Be sure to resume an ordinary room
temperature on the battery pack and then leave it unattended for approximately one hour before charging.
— Avoid the battery pack with a full of the capacity to store for a long period of time. If you need to store it for a long period, be sure that the
remaining capacity is 30 to 50 percent and to store in a moderate low temperature. This can reduce deterioration.
— The battery pack gradually deteriorates over time. In particular, storing (or using) the fully charged battery pack at high temperatures
tends to accelerate battery pack deterioration.
