Getting the Best
Performance From the
Battery
• If the ambient temperature is low, the battery
performance deteriorates, reducing the operating time.
To maximize the operating time, the following
techniques are recommended.
– Keep the battery warm in a pocket, and load it into
the unit immediately before shooting.
• During recording or playback, power off whenever the
unit is not operating.
• Have enough batteries ready to last two or three times
the expected shooting duration, and test shoot with
them before the session.
• The battery is not waterproof. Be careful not to allow
it to get wet.
Indication of remaining battery capacity
If the battery fails even though the indication suggests
there is adequate capacity, fully recharge the battery.
This will correct the remaining capacity indication.
However, if the battery is used for a long time at high
temperature, is left fully charged, or has been very
heavily used, the indication may not be correctly
restored. In this case, use the indication time as a rough
guideline to estimate the remaining capacity.
Battery storage
• If the battery is not used for a long time, to maintain
its performance, it should be fully charged and then
fully discharged with this unit about once a year.
Remove the battery from the unit, and store in a cool
dry place.
• To fully discharge the battery with this unit, leave it
powered on until the battery is exhausted.
Battery lifetime
• The battery has a limited lifetime. As it is repeatedly
used over a long time interval, the capacity gradually
reduces. When the operating time is much less than
the original value, it is time to replace the battery.
• The lifetime varies from one individual battery pack to
another, depending on the pattern of use, and how it
has been stored.
