OPTIMUM BATTERY PERFORMANCE
New batteries.
Between manufacturing and first use, all
batteries exhibit some drain. Therefore, care should be
taken to purchase the newest (and freshest) ones possi­
ble. To help you do this, some manufacturers stamp the
date of manufacture on the bottom of each battery. Ask
your camera dealer for assistance in interpreting the
codes.
Temperature.
Battery life ratings are based on operation
at around 25°C (77°F). At other temperatures, battery
life is shortened. Spare batteries should therefore be kept
available if operation in low temperatures is anticipated. Continuous use.
Batteries are drained much more quick­
ly by Continuous use than by intermittent use. Storage.
When not in use, the batteries should be re­
moved to prevent damage from leakage. To minimize
drain during the period of disuse, store the batteries in a
cool, dry place below 20°C (68°F).
Battery brands.
Do not mix brands of batteries, nor use
batteries with different model numbers. Also, avoid mix­
ing 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. Polarity.
When installing batteries, observe the voltage
polarities carefully. Reversal of the positive (-I-) and neg­
ative (-) terminals will result in leakage. If leakage
should occur, take the SB-11 to your dealer. NiCd batteries.
In comparison with regular batteries,
NiCd batteries provide faster recycling time and better
efficiency at low temperatures. However, note that the
recycling time and the number of flashes per battery set
are dependent on the age of the batteries, how much
charge they have, and their capacities.
