Lower
Temperature
Conditions:
Air
holds
less
moisture
as
temperature
decreases,
and
the
difference
between
low
and
high
relative
humidity
becomes
less
significant.
At
0°C,
the
difference
between
the
humidity
of
the
PP355
and
the
environment
is
negligible.
While
the
service
obtained
from
a
PP355
at
temperatures
lower
than
standard
conditions
is
less,
the
loss
is
similar
to
Alkaline
batteries.
In
general
the
“up
to
3X”
service
advantage
for
Zinc
Air
batteries
over
Alkaline
batteries
is
maintained.

was

to
the

conditions
for
the
entire
test
duration.

the

from
a

battery
at

In
summary,
the
PP355
battery
sustains
a
significant
performance

over
similar

Alkaline

with
varying
intermittency
in
extreme
temperature

2.3
‐‐
Pulse
Capability
The
pulse
capability
of
Zinc
Air
batteries
is
dependent
on
the
instantaneous
amount
of
oxygen
available
at
the
air
electrode
at
a
given
time.
While
the
PP355
battery
can
continuously
discharge
at
rates
up
to
100
mA,
the
battery
can
provide
significantly
more
current
in
short
bursts.
Figure
8
demonstrates
that
a
fresh
PP355
battery
can
provide
pulses
of
up
to
1500
mA,
depending
on
the
duration
of
the
pulse.
The
pulse
capability
of
a
Zinc
Air
battery
can
also
be
affected
by
the
frequency
of
the
pulses.
Pulse
capability
will
drop
over
time
without
sufficient
time
for
more
oxygen
to
enter
the
air
electrode.
