Appendix

Battery,
Warranty,
and
Service
Information
Batteries
The
HP-11C
is
powered
by
three
batteries.
In
“typical”
use,
the
HP-11C
has
been
designed
to
operate
6
months
or
more
on
a
set
of
alkaline
batteries.
The
batteries
supplied
with
the
calculator
are
alkaline,
but
silver-oxide
batteries
(which
should
last
twice
as
long)
can
also
be
used.
A
set
of three fresh alkaline
batteries
will
provide
at
least
80
hours
of
continuous
program
running
(the
most
power-consuming
kind
of
calculator
use*).
A
set
of
three
fresh
silver-oxide
batteries
will
provide
at
least
180
hours
of
continuous
program
running.
If
the
calculator
is
being
used
to
perform
operations
other
than
running
programs,
it
uses
much
less
power.
When
only
the
display
is
on—
that
is,
if
you
are
not
pressing
keys
or
running
programs—very
little
power
is
consumed.
If
the
calculator
remains
turned
off,
a
set
of
fresh
batteries
will
preserve
the
contents
of
Continuous
Memory
for
as
long
as
the
batteries
would
last
outside
of
the
calculator—at
least
12
years
for
alkaline
batteries
or
at
least
2
years
for
silver-oxide
batteries.
The
actual
lifetime
of
the
batteries
depends
on
how
often
you
use
the
calculator,
whether
you
use
it
more
for
running
programs
or
more
for
manual
calculations,
and
which
functions
vou
use.*
WARNING
Do
not
attempt
to
recharge
the
batteries;
do
not
store
batteries
near
a
source
of
high
heat;
do
not
dispose
of
batteries
in
fire.
Doing
so
may
cause
the
batteries
to
leak
or
explode.
*
Power
consumption
in
the
HP-11C
depends
on
the
mode
of calculator
use:
off
(with
Continuous
Memory
preserved);
idle
(with
only
the
display
on);
or
“operating”
(running
a
program,
performing
a
calculation,
or
having
a key
pressed).
While
the
calculator
is
turned
on,
typical
calculator
use
is
a
mixture
of
idle
time
and
‘“operating”
time.
Therefore,
the
actual
lifetime
of
the
batteries
depends
on
how
much
time
the
calculator
spends
in
each
of
the
three
modes.
