OPTIMUM BATTERY PERFORMANCE
1. New batteries: Between manufacturing 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 manu­
facture on the bottom of each battery. Ask your
camera dealer for assistance in interpreting the
codes.
2. Temperature: Battery life ratings are based on
operation at around 20°C (68°F). At other tem­
peratures, battery life is shortened. At 0°C, for
instance, battery life is shortened by as much as
2/3. Spare batteries should therefore be kept
available if operation in low temperatures is
anticipated.
3. Continuous use: Batteries are drained much
more quickly by continuous use than by inter­
mittent use.
4. Storage: When not in use, the batteries should
be removed to prevent damage from leakage. To
minimize drain during the period of disuse,
store the batteries in a cool, dry place.

Battery brands: Do not use mixed brands of
batteries, nor batteries with different model
numbers. Also, avoid mixing new and old bat­
teries since proper performance will not be ob­
tained and battery leakage may occur.
Disposal: Do not dispose of batteries by burning.
Also, for safety's sake, do not disassemble bat­
teries when disposing.
Polarity: When installing batteries, observe the
voltage polarities carefully. Reversal of the posi­
tive (
-I-
) and negative (—) terminals will result
in leakage.
