About the battery

The battery used in this unit is a rechargeable
lithium-ion battery. It is susceptible to humidity
and temperature and the effect increases the
more the temperature rises or falls. In cold
areas, the full charge indication may not appear
or the low battery indication may appear about
5 minutes after starting use. At high
temperatures, the protection function may be
triggered, making it impossible to use the unit.
Be sure to detach the battery after use.
≥ If the battery is left attached, a minute amount
of current continues to flow even if the unit is
off. Keeping the unit in this state may result in
over discharge of the battery. This may result
in you not being able to use the battery even
after it is charged.
≥ The battery should be stored in the vinyl bag
so metal does not come into contact with the
terminals.
≥ The battery should be stored in a cool place
free from humidity, with as constant
temperature as possible. (Recommended
temperature: 15 oC to 25 oC (59 °F to 77 °F),
Recommended humidity: 40%RH to 60%RH)
≥ Extremely high temperatures or low
temperatures will shorten the life of the
battery.
≥ If the battery is kept in high-temperature,
high-humidity, or oily-smoky places, the
terminals may rust and cause malfunctions.
≥ To store the battery for a long period of time,
we recommend you charge it once every year
and store it again after you have completely
used up the charged capacity.
≥ Dust and other matter attached to the battery
terminals should be removed.
