On the battery pack
Use only an NP-FM55H battery pack. Note
that the NP-FM50 and NP-FM30 cannot be
used.
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
When using the camera with the battery pack, the
remaining time in minutes is not indicated.
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.
