On the “InfoLITHIUM” battery pack
Use only an NP-FM500H battery pack.
What is an “InfoLITHIUM” battery
pack?
An “InfoLITHIUM” battery pack is a lithium-ion
battery pack that has functions for exchanging
information related to operating conditions with
your camera. Using the “InfoLITHIUM” battery
pack, the remaining battery time in percent figures
is displayed according to the operating conditions
of your camera.
On charging the battery pack
We recommend charging the battery pack in an
ambient temperature of between 10 to 30°C (50 to
86°F). You may not be able to efficiently charge
the battery pack outside of this temperature range.
Effective use of the battery pack
• Battery performance decreases in low
temperature surroundings. So, the time that the
battery pack can be used is shorter in cold
places. We recommend the following to ensure
longer battery pack use:
– Put the battery pack in a pocket close to your
body to warm it up, and insert it in your
camera immediately before you start
shooting.
• The battery pack will run out quickly if you use
the flash frequently.
• We recommend having spare battery packs
handy, and making trial shots before taking the
actual shots.
• Do not expose the battery pack to water. The
battery pack is not water-resistant.
• Do not leave the battery pack in extremely hot
places, such as in a car or under direct sunlight.
On the remaining battery indicator
The power may go off although the battery
remaining indicator shows there is enough power
to operate. Use the battery pack up and charge the
battery pack fully again so that the indication on
the battery remaining indicator is correct. Note,
however, that the correct battery indication
sometimes will not be restored if the battery pack
is used in high temperatures for a long time, left in
a fully charged state or used frequently.
How to store the battery pack
If the battery pack is not to be used for a long
time, fully charge it and then fully use it up once a
year on your camera before storing the battery
pack in a dry, cool place. Repeat this charging and
using up once a year to maintain the battery
pack’s function.
On battery life
• The battery life is limited. Battery capacity
decreases little by little as you use it more and
more, and as time passes. If the battery
operating time seems shortened considerably, a
probable cause is that the battery pack has
reached the end of its life. Buy a new battery
pack.
• The battery life varies according to how it is
stored and the operating conditions and
environment in which each battery pack is used.
