■ Using the Li-ion Battery Pack
• Charge the battery pack before using it.
• To keep the battery discharge at a minimum, remove the
battery pack from the equipment when it is not in use. Store
the battery pack in a cool and dry location.
• When storing the battery pack for a long period:
1 Remove the battery pack from the equipment.
2 Discharge the battery pack, if possible.
3 Store the battery pack in a cool (below 25°C/ 77°F) and dry
location.
■ Characteristics of the Li-ion Battery Pack
• As the battery pack is charged and discharged repeatedly, the
battery capacity decreases.
• Even if the battery pack is unused, the battery pack degrades.
• It takes a longer time to charge the battery pack in cooler
areas.
• The life of battery pack is shortened when it is charged and
discharged in hotter areas. When the battery pack is stored in
a hot location, the battery pack degrades quicker. Do not leave
the battery pack in vehicles or near heating appliances.
• When the battery pack operating time becomes short, even
if it is fully charged, replace the battery pack. Continuing to
charge and discharge the battery pack may result in electrolyte
leakage.
