battery
attached,
25ºC
ambient
temperature
Example
2
has
the
same
charging
time
(indicated
by
the
blue
arrow)
as
in
example
1
(6
hours
30
minutes);
at
this
time
the
battery
is
fully
charged;
checking
using
the
AT^SBV
command,
we
discover
that
it
is
around
4.40V
(indicated
by
the
green
arrow).
Discharging
time
in
these
conditions
is
around
12
hours,
so
the
more
often
you
connect
to
GPRS,
the
shorter
the
battery
will
last.
Keep
GPRS
connections
short
and
infrequent
where
possible
to
extend
battery
life
if
you
require
longer
periods
of
use
without
charging.
Note:
there
are
two
internal
LEDs
that
provide
information
about
the
battery
status:
A
red
LED
will
illuminate
when
the
battery
is
charging.
A
green
LED
will
illuminate
when
external
power
is
applied.
