While
the
voltage
of
the
rechargeable
battery
pack
can
be
checked
in
the
same
way
as
for
regular
batteries,
this
is
not
a
reliable
index
of
the
remaining
operating
life,
since
a
nickel-
cadmium
battery
such
as
the
BP-33
will
furnish
a
nearly
constant
voltage
up
to
the
end
of
its
capacity,
and
then
drop
quickly
to
a
low
value.
Keeping
a
record
of
the
time
in
actual
use
is
the
most
reliable
measure
of
remaining
battery
life
when
using
nickel-
cadmium
batteries.
