Batteries:
Batteries
may
leak
or
explode
if
improperly
handled.
Observe the
following
precautions
when
handling batteries:
•
Use
only
batteries approved for
use
in this equipment.
•
Do
not expose the battery to
flame
or excessive heat.
•
Keep
the battery
terminals clean.
•
Turn the product
off
before
replacing the battery.
•
Remove the battery from the
camera
or
charger when
not
in
use and
replace
the
terminal
cover.
These
devices draw minute
amounts
of
charge even when off
and
could
draw the battery down
to
the point that
it
will no
longer
function.
If
the battery
will
not
be
used
for some time, insert
it
in the
camera
and
run
it
flat
before
removing
it
and
storing
it
in a
location
with
an
ambient temper-
ature
of
15
oc
to
25
oc (59
oF
to
77
oF;
avoid hot or extremely cold
locations).
Repeat this process at
least
once every
six
months.
• Turning the camera on and
off
repeatedly
when
the
battery
is
fully discharged
will
shorten bat-
tery life.
Batteries that have been
fully
discharged must
be
charged
before
use.
•
The
internal
temperature
of
the
battery may
rise
while
the battery
is
in use.
Attempting
to
charge
the
battery
while
the
internal
temperature
is
elevated
will
impair battery performance, and
the
battery
may
not
charge
or
charge only partially.
Wait for the
battery to cool
before charging.
•
Continuing
to
charge the battery
after
it
is
fully charged
can
impair
battery performance.
•
A marked drop in the time a fully
charged battery retains its charge
when
used
at room temperature
indicates that
it
requires
replace-
ment. Purchase a new
EN-EL20
battery.
• Charge
the battery before
use.
When
taking
photographs
on
important
occasions, ready a
spare
EN-EL20
battery and keep
it
fully charged. Depending on your
location,
it
may
be
difficult
to
pur-
chase replacement batteries on
short notice. Note
that
on cold
days,
the
capacity
of
batteries
tends
to
decrease.
Be
sure
the
battery
is
fully
charged before
taking
photographs
outside
in
cold
weather. Keep a spare bat-
tery
in
a
warm
place
and
exchange the
two
as
necessary.
Once warmed, a cold
battery may
recover some
of
its charge.
•
Used
batteries
are
a valuable
resource; recycle
in accord
with
local regulations.
