MAINTENANCE LOG
Customers
are
advised
to
keep
a
complete
and
up-to-date
maintenance
log
on
each
battery.
This
information
will
help
determine
the
source
of
any
battery
problems
and
will
assist
in
substantiating
warranty
claims.

PRE-INSTALLATION
INSTRUCTIONS
FOR NICKEL-CADMIUM
BATTERIES
Unless
otherwise
indicated
by
a
red
warning
tag,
a
nickel-cadmium
battery
is
shipped
in
fully
discharged
state
and
contains
the
proper
amount
of
electrolyte.
Observe
the
following
precautions
to
ensure
maximum
performance
and
protect
battery
warranty:
a.
Do
not
remove
the
shorting strap
until
prepared
to
charge
the
battery.
Batteries
from which
the
shorting
strap
has
been
removed
(for
even
a
short
period
of
time)
must
be
considered
in
an
unknown
state
of
charge
condition
and
must
be
completely
discharged prior
to
charging
and installation.
b.
Inspect
batteries
shipped
from the
factory
for
shipping plugs
in the
vent
holes
of
each
of
the
battery
cells.
The
blunt
aluminum
screws
that
serve as
shipping plugs
must
be
removed
prior
to
operation
of the
battery.
The
Bunson
valves,
included
with
the
battery
in
a
separate
plastic
bag,
should
then
be
screwed into the
vent
cap
assembly
in
place
of the
screw
plugs.
The
Bunson valves
will
release excessive
pressure
from
gas
accumulation to
prevent
cell
rupture.
NOTE: On batteries
not
equipped
with
the
screw-type
plugs
and
Bunson
valves,
remove
the
shipping
plugs
and
clean
the
filler-cap
vent
plugs
as
noted
under BATTERY
CLEANING.
Retighten
the cell
vents
with
the
vent
plug
wrench
included
with
the
battery.
c.
Check
for
a
torque
of
6
ft-lbs
on
the terminal
screws
securing
the
cross
links
connecting
the
cells
together.
d.
Before
charging,
determine
that
all
cells
are
properly
installed
by
making
a
cumulative
voltage
check.
e.
After
determining
the
battery
is
in
good
physical
condition
and
is
properly
assembled,
it
should
be
charged
as
outlined
under
BATTERY
CHARGING
and
the
electrolyte
level
adjusted.
