Battery
Information
for
the
RX2106
Model
The
RX2106
station
uses
one
rechargeable
NiMH
battery
pack
(HRB
‐
NiMH
‐
6).
Typical
battery
life
is
3–5
years
when
operated
in
the
temperature
range
‐
20°
to
40°C
(
‐
4°
to
104°F);
operation
outside
this
range
will
reduce
the
battery
service
life.
Use
the
AC
adapter
(P
‐
AC
‐
1),
built
‐
in
solar
panel,
or
external
solar
panel
(SOLAR
‐
xW)
to
keep
the
battery
charged.
If
using
an
external
solar
panel
or
built
‐
in
solar
panel,
the
quality
and
quantity
of
solar
light
can
affect
whether
the
battery
is
sufficiently
charged
to
last
through
the
night
and
cloudy
periods.
The
maximum
connection
rates
when
using
the
built
‐
in
solar
panel
in
full
sun
are:
10
minute
connections
year
round
for
latitudes
less
than
±40°
10
minute
connections
through
three
seasons
in
other
regions,
reduced
to
30
minute
connections
in
winter
The
maximum
connection
rate
when
using
an
external
5W
or
15W
solar
panel
is
10
minute
connections
year
round,
in
full
sun.
The
connection
rate
with
external
solar
panels
may
be
less
if
deployed
in
partial
sun.
Battery
life
for
the
RX2106
model
is
1
month
without
solar
recharging,
with
hourly
connections,
a
1
‐
minute
logging
interval,
and
approximately
10
motes.
Deployments
in
extremely
cold
or
hot
temperatures,
a
logging
interval
faster
than
1
minute,
or
a
sampling
interval
faster
than
15
seconds
can
impact
battery
life.
Estimates
are
not
guaranteed
due
to
uncertainties
in
initial
battery
conditions
and
operating
environment.
If
using
an
external
solar
panel
or
built
‐
in
solar
panel,
the
quality
and
quantity
of
solar
light
can
affect
whether
the
battery
is
sufficiently
charged
to
last
through
the
night
and
cloudy
periods
The
station
will
shut
down
once
the
battery
voltage
drops
to
6
V.
Plug
in
an
AC
adapter
or
solar
panel
to
recharge
it.
Once
the
voltage
rises
to
7.5
V,
the
station
will
power
up.
If
the
charging
device
is
not
recharging
a
dead
battery,
