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 O°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 sho\.lld
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.
6.
Disposal: Do not dispose
of
batteries by burning.
Also, for safety's sake, do not
disassemble
bat-
teries when disposing.
7.
Polarity: When
installing
batteries,
observe
the
voltage polarities
carefully.
Reversal
of
the
posi-
tive
(+)
and negative (-) terminals will result
in leakage.
