Getting The Best Performance From The Battery Pack - Sony HVR-Z7E Operating Manual

Getting the best performance from the battery pack

• If the ambient temperature is low, the battery pack
performance deteriorates, reducing the operating time. To
maximize the operating time, the following techniques are
recommended.
– Keep the battery pack warm in a pocket, and load it into
the unit immediately before shooting.
• The battery is depleted when this unit is in recording
standby or playback pause. Always switch off the power
supply to save energy.
• Have enough battery packs ready to last two or three times
the expected shooting duration, and test shoot with them
before the session.
• The battery packs are not waterproof. Be careful not to
allow them to get wet.
Indication of remaining battery pack capacity
If the battery pack fails even though the indication suggests
there is adequate capacity, fully recharge the battery pack.
This will correct the remaining capacity indication. However,
if the battery pack 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 pack storage
• If the battery pack 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 pack from this unit, and store in a cool dry place.
• To fully discharge the battery pack with this unit, leave it
powered on until the battery pack is exhausted.
Battery pack lifetime
• The battery pack 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 pack.
• The lifetime varies from one individual battery pack to
another, depending on the pattern of use, and how it has
been stored.
