Charge
Gauge
By
either
pressing once
or pressing and holding the
status
button on the
charge gauge
on the
battery,
you
can
check:
•
Battery charge (check by pressing and releasing
the
status
button)
•
Battery health (check by pressing and holding
the
status
bu
tton)
The
battery operating
time
is largely determined by
the
number
of
times
it
is charged.
After
hundreds
of
charge and discharge cycles, batteries lose some charge capacity—or battery health.
That
is, a battery
can
show a status
of
"charged"
but maintain
a reduced charge capacity
(health).
Check the Battery
Charge
To
check
the
battery charge,
press
and
release
the
status
button on the
battery charge gauge
to
illuminate
the
charge-level lights. Each
light
represents approximately 20 percent
of the total
battery charge.
For
example,
if the
battery has 80 percent
of its
charge remaining,
four of the lights
are on.
If no lights
appear,
the
battery has
no charge.
