CHARGING THE BATTERY
With the battery removed from the camera, insert the jack
plug from the battery charger into the socket on the battery
grip. Insert the battery charger into a standard (100–240V~
/50–60 Hz) domestic socket.
During the charging procedure, the lamp on the charger
signifies the following:
• The battery should be charged for approximately 6 hours
before first time use.
• The battery must be charged at room temperature.
• Maximum battery capacity is reached only after the bat-
tery has been charged and discharged several times.
• Avoid frequent full discharges (a full discharge is signalled
by the appearance of the Replace battery warning on
the grip display). As the battery is a Li-ion type, it has no
‘memory effect’ of practical importance and therefore fre-
quent recharges will cause no problems such as loss of ca-
pacity or poor performance. It is therefore better policy to
recharge the battery at very regular intervals, regardless
of use.
• Remove the battery if you intend to store the camera
for some while as it will eventually become completely
drained, even though the camera is turned off.
• The battery has an integrated ‘fuel gauge’ capability that
supports the Replace battery and Battery status functions
on the grip display. As with most Li-ion batteries, this ca-
pability should be occasionally calibrated, depending on
how much the battery is used. To do this, leave the camera
on (or use it), until the Replace battery warning appears.
Then, recharge the battery for 6 hours. This will improve
the accuracy of the measurements.
• When removing a battery from the charger and imme-
diately replacing it with another, allow a few seconds to
elapse so that the charger can automatically reset for the
next charging procedure.
• It is perfectly normal for the battery to become warm
when being charged.
• A slight temporary loss of battery performance might
be noticed at very high or low temperat ures. Take the
appropriate measures if this is the case.
• If you do not intend to use the battery for a while, it is best
to store it at room temperature with an approximate 30
to 40% charge. You can check the percentage level on the
status screen.
• The battery should have a usable service life of around
400 recharge/discharge cycles.
• Connect the battery grip to the camera correctly.
• Keep the protective cover in place when not in use. (Short-
circuiting across keys in a pocket, for example, could cause
a fire risk).
• Do not immerse the battery grip in liquids.
• Do not incinerate the battery grip. Please recycle or dis-
card in an environmentally approved manner.
• Use indoors only (protect against moisture).
• Do not short-circuit the jack plug.
• Do not alter the charger in any way other than changing
the plug attachment.

– PRECAUTIONS & GENERAL
Standby (no battery connected) Charging Ready
Note
It can take about 6 hours
to charge the battery
completely the first time.
Tip
You can save battery consumption by changing the Power
mode setting.
BATTERY LIFE & BATTERY WARNING
Battery life is dependent on a number of variable factors
and therefore cannot be exactly predicted. If the camera is
left in the active state instead of Display Off or Sleep modes
for long periods, for example, then the battery will become
exhausted much faster. A low camera battery state is indi-
cated by a symbol on the grip display, in the viewfinder as
well as on the sensor unit display. In addition, an audible sig-
nal sounds.
When the battery is almost completely exhausted, a warn-
ing message Replace battery will appear on the grip dis-
play.
