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.
5. 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.
