• The battery pack is a consumable. If you
are able to use the instrument for only a
limited period of time despite the battery
pack being properly charged, the battery
pack's service life is at an end, and it
should be replaced.
• When a battery pack that has not been
used for a long time is used, charging may
end before the battery pack is fully
charged. In such a case, repeat charging
and discharging a number of time before
use. (A battery pack may also be in such a
state immediately after purchase.)
• The life of the battery pack (when capacity
is 60% or more of initial capacity) is
approximately 500 charge-discharge
cycles. (The life differs depending on the
conditions of use.)
• To prevent battery pack deterioration
when the battery will not be used for 1
month or longer, remove it and store it in a
dry location with an ambient temperature
range of between -20°C to 30°C. Be sure
to discharge and charge it every two
months. Long-term storage at low battery
capacity will reduce performance.
• When a battery pack is used, the
instrument turns off automatically when
the capacity drops. Leaving the
instrument in this state for a long time may
lead to over discharge so be sure to turn
off the power switch on the instrument.
• The charging efficiency of the battery pack
deteriorates at high and low
temperatures.
