This
will probably
indicate
that the battery is well charged.
Under
these circumstances,
switching
on
the
headlamps may
cause
a
discharge reading
to
be
shown,
but this
will
only occur
ior
a
short
time,
as
the
dynamo will
quickly respond
to the slightest
drop in
battery
voltage,
due
to the
discharge, and re-adjust
the output
accordingly.
An
unnoticed
reversal
of
the ammeter connections
causes
the
charge
and
discharge indications
to be
reversed.
Battery.
The battery recommended
and specified for
this car, is
as follows:-

The full

be
given
when
ordering
a replacement
battery
or spare
parts.
First
Charge.
If the battery.
i,s
received
in
a
dry
condition,
it
will
be
necessary
to
fill
the cells
with
acid
solution
of
the
correct
specific
gravity
and
charge
the battery,
before
it
is put
into
use.
In such
cases,
it is
strongly
recommended
that
the
necessary
charging
should
be undertaken
by
. properly
equipped
service station,
as
urilesi
the
initial
charge
is correct
the
battbry
will
never give
satisfactory
servtce.
Topping-Up.
.
In
the majority
of
cases,
however,
the
battery
will have
already
been
charged
and
the cells
filled
with
acid
solution.
Under normal
op.erating
conditions
the level
of
the
solution
will
gradually
fall in
each
cell, mainly
owing
to- evaporation
losses.
A regular
inspection
should
be
made,
as
directed
on
page
3o,
to
see
thai the
level of
the
acid.
solution
has not
fallen
to
such
an
extent
that the
tops of
the separators
and plates
are
exposed.
I1 this case,
the battery
should
be
"topped-up",
by removing
the
vent'Pl"g.in
the centre
of
each

lid
^"ita
utiaing"distilled
water
to each cell;
until
the level
of
the
solution is
approximately
f-"
above
the
tops of
the
separators.
It is
difficult.to-lay
down
a
hard
and fast
rule
as
to
how frequently
"topping-up"
qilt
.be.required,
because
this
varies
so
much,
according
to the
use
to which
the car
is
put,
and also
the temperature
in
whic6
it operates.
It must
be
remembered
that
"topiing-up"
will
be
necessary more
frequently
in
hot
weather
than in Cold.
