The
two basic
methods
of
charging
nickel-cadmium
batteries
are
the
constant

constant
current
methods.
Variations
of
the
two basic
methods
may
be
incorporated
in automatic
equipment.
WARNING:
Complete servicing
of
the
battery
is
required
if
the

Special
Notes
on
Charging
The
following
special
comments
are
made with
respect

a.
Charging
is
most
efficient
at
battery
temperatures
between
400 and
800F.
b.
Two
or
more
batteries
may
be
charged
in
parallel
on
a
constant
potential charging
bus,
provided
the
charging
equipment
has
the
proper
current
producing capability.
c.
Do
not
charge
batteries
in
parallel
using
the
constant
current
method.
d.
Do
not
charge
individual
cells
unless the
plastic
case
is
supported
on
each
side.
A
special
frame
may
be
built
to fit the
cell,
or
two
boards
or
plates
may
be
placed
on
each side
of
the
cell and
held
together
by
a
C-clamp.
The
sides
of
the cell
must
be
kept
flat
during
charging.
e.
Perform
necessary
inspection,
cleaning
and
repairs
before

the
charging
circuit.
g.
When
charging
a
battery
in
the
shop,
a
thermometer
should be
placed
so
that
the
bulb
is below
and
between
the
top
of the
cells.
Do
not
place
on
charge
any
battery
that
has
a
temperature
of
1
OO"F
or
