OPTIMUM BATTERY PERFORMANCE
1. New batteries | 7. Polarity |
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 . Also, for safety's sake, never disassemble batteries .
When installing batteries, observe the voltage polarities carefully. Reversal of the positive (+ ) and negative

8.NiCd batteries
In comparison with regula r batteries, 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.
