1.
New
batteries
Between manufacture and first
use
, all batteries
exhibit some drain. Therefore, care should
be
taken to purcha
se
the newest (and freshest) ones
possible.
To
help
you
do this, some manufacturers
stamp the date of manufacture
on
the bottom of
each battery. A
sk
your camera dealer for a
ss
is
t-
ance
in
interpreting the code
s.
2.
Temperature
Battery life ratings are based
on
op
eration
at
around 25°C
(7YOF).
At
other temperatures, bat-
tery life
is
shortened. Spare batteries should there-
fore
be
kept available if operati
on
in
low temper-
atures is anticipated.
3. Continuous use
Batteries are drained much more quickly
by
con-
tinuous
use
than by intermittent
use
.
4. Storage
W
hen
not
in
use
, the batteries should
be
removed
to prevent leakage which may damage the unit,
or
even cause combustible gases to
be
trapped
inside the battery chamber.
To
minimize dra
in
during the period of
di
suse, store the batteries
in
a cool, dry place below 20°C (68°
F).
5. Battery brands
Do not m
ix
brands of batteries or
use
batteries
with different model number
s.
Also, avoid
mi
x
ing
new
and
old batteries since proper performance
will not
be
obtained and battery leakage may
occur.
6. Disposal
Do
not
di
spose of batteries
by
burning.
Al
so, for
safety's sake, never
di
sassemble batteries.
7. Polarity
W
hen
installing batterie
s,
ob
serve the voltage
polarities carefully. Reversal of the positive
(+
)
and
negative
(-)
terminals will r
es
ult
in
leakag
e.
If
leakage should occur, clean the SB-102 carefully
or take
it
to
an
authorized Nikon dealer or service
center.
The
SB-
102 requires
an
ex
ce
ss
ive
current, so
th
e
life span of the batteries may
be
shorter
th
an
other speedlight
s.
8. NiCd batteries
In
comparison with regular batte
rie
s,
NiCd bat-
teries provide faster recycling and higher effi-
ciency
at
low temperatures. However, the
re
-
cycl
ing
time
and
the number of flas
he
s per bat-
tery s
et
depend upon the
age
of the batterie
s,
their charges,
and
their capacitie
s.
o Do not continue to use NiCd batteries after they are exhausted.
Continued use may reduce their life span
or
cause leakage.
o Before charging, thoroughly read the battery and battery
charger instructions.
oCharging should only be done for the designated number
of
hou
rs
on a battery charger recommended by the battery manu·
facturer. Excessive charging may cause battery deterioration.
oCharging should only be done
in
temperatures between 5°C
(41°F) and 35°C (95°F). Never charge batteries while they are
still hot from
use.
o Never attempt to charge NiCd batteries that are incorrectfy
installed
in
the battery charger.
o
The
charging capacity of NiCd batteries may be shortened
after
a long period
of
storage. If this occurs, discharge and
recharge them several times.
o
lf
working time is markedly reduced even
after
they have been
correctly charged, replace them with
a fresh set.
o Do not mix new and old NiCd batteries.
o Do not use NiCd batteries which have been charged for differ-
ent lengths
of
time.
