Filling the Cells
Remove the seals from the cell filling
holes and fill each cell with correct
specific gravity electrolyte to the top
of the separators IN ONE OPERA-
TION. The temperature of the
filling room, battery and electrolyte
should be maintained at between 60°F.
and 100°F. If the battery has been
stored in a cool place it should be
allowed to warm up to room tempera-
ture before filling.
Batteries filled
in
this way are up
to go per cent charged, and capable
of giving a starting discharge ONE
HOUR AFTER FILLING. When
time permits, however, a short freshen-
ing charge will ensure that the battery
is fully charged. Such a freshening
charge should last for no more than
4
hours at the normal re-charge rate of
the battery.
During the charge the electrolyte must
be kept level with the top edge of the
separators by the addition of distilled
water. Check the specific gravity of
the acid at the end of the charge ; if
1.270 acid was used to fill the battery
the specific gravity should now be
between 1.270 and 1 B 0 ; if 1.210,
between 1.210 and 1.230.
Maintenance in Service
After fi&ng, a dry-charged battery
needs only the attention normally given
to lead-acid type batteries.
GENERATOR-MODEL C.39 PV/2
I.
GENERAL
The generator is a shunt-wound two-pole
two-brush machine, arranged to work in
conjunction with a compensated voltage
control regulator unit. A fan, inte a1
K
with the driving pulley, draws coo
'
g
air through the generator, inlet and outlet
holes being provided in the end brackets
of the unit.
The output of the generator is controlled by
the regulator and is dependent on the state
of charge of the battery and the loading of
the electrical equipment in use. When the
battery is in a low state of charge, the
generator gives a high output, whereas if the
battery is fully charged, the generator gives
only sufficient output to keep the battery
in good condition without any possibility
of overcharging. An increasein output is
given to balance the current taken by lamps
and other accessories when in use. Further,
a high boosting charge is given for a few
minutes immediately after starting.
