monthly.
If

specific
gravity
tests
1.225
or
less,
the
battery
should
be
removed
and
thoroughly
recharged.
At
the
same
time
the
solution
level
should
be
examined
and
distilled
water
added
when
necessary
to
retain
the
level
of
3/16
inch
over
the
plates.
When
necessary
to
add
distilled
water
it
should
always
be
done
just
prior

re¬
charging
to
mix
the
added
water
thoroughly
into
the
solution.
When
recharging
is
necessary
and
user
does
not
have
his
own
charging
equipment,
he
should
request
service
station
to
slow

use.
Vent
caps
should
be
kept
tight
and
the
small
vent
holes
in
top
or
side
of
cap
be
kept
open
at
all
times
to
permit
escapage
of
gases
formed
in
the
battery.
Care
should
be
exercised
not
to
overfill
the
battery
at
any
time
and
to
always
retain
3/16
inch
of
solution
above
the
plates.
