OPTIMUM BATTERY PERFORMANCE
32
1.
New batteries
Between manufacture and first
use,
all batteries
exhibit some drain. Therefore
,
care should be
taken to purchase the newest (and freshest)
ones
possible.
To help you do this
,
some manufacturers
stamp the date of manufacture on the bottom of
each battery. Ask your camera dealer for assist-
ance in interpreting the
codes.
2.
Temperature
Battery life ratings are based on operation at
around 25°C (7YOF). At other temperatures
,
bat-
tery life is shortened
.
Spare
batteries should there
-
fore be kept available if operation 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
When 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 drain
during the period of
disuse,
store the
batteries
in
a cool
,
dry place below 20°C (68° F).
5.
Battery brands
Do not mix brands of batteries or use batteries
with different model
numbers. Also,
avoid mixing
new and old
batteries
since proper performance
will not be obtained and battery leakage may
occur.
6.
Disposal
Do not dispose of
batteries
by burning
.
Al
so,
for
safety's sake, never disassemble
batteries.
7.
Polarity
When installing
batteries,
observe the
voltage
polarities
carefully.
Reversal of the positive (+ )
and negative (-)
terminals
will result in
leakage.
If
leakage shou ld
occur,
clean the SB-102 carefully
or take it to an authorized Nikon dealer or service
center.
The
SB-102 requires
an excessive current
,
so th
e
life span of the
batteries
may be shorter than
other
speedlights.
8.
NiCd batteries
In comparison with regula
r
batterie
s,
NiCd
bat-
teries provide faster recycling and higher
effi-
ciency at low temperatures
.
However, the re
-
cycling time and the number of
flashes
per bat-
tery set depend upon the age of the
batteries,
their charges
,
and their
capacities.
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
hours
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.
olf 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.
