OPTIMUM BATTERY PERFORMANCE
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 (77°F). 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.

Disposal
Do not dispose of batteries by burning. Also, 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 should 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 the
life span of the batteries may be shorter than
other speedlights.

NiCd batteries
In comparison with regular batteries, NiCd bat­
teries provide faster recycling and higher effi­
ciency at low temperatures. Flowever, 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.
• Do not continue to use NiC d batteries after they are exhausted.
Continued use may reduce their life span or cause leakage.
•Before charging, thoroughly read the battery and battery
charger instructions.
• Charging 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.
• Charging should only be done in temperatures between S^C
(41 °F) and 35°C(95°F). Never charge batteries while they are
still hot from use.
•Never attempt to charge NiCd batteries that are incorrectly
installed in the battery charger.
•The charging capacity of NiC d batteries may be shortened
after a long period of storage. If this occurs, discharge and
recharge them several tim es.
•If working time is markedly reduced even after they have been
correctly charged, replace them with a fresh set.
• Do not mix new and old NiCd batteries.
•Do not use NiCd batteries which have been charged for differ­
ent iengths of tim e.
