bled similar to
Exide starting and lighting batteries, except that the plates are
considerably thicker, wood and rubber separators are used, and the
terminal posts are shaped to provide for bolted instead of burned-on
connection. The method of sealing and unsealing the cells is the same
as in Exide starting and lighting batteries.

All instructions already given for glass for cells apply to rubber jar
cells except for a few differences in assembling and disassembling.

Care should be taken to keep the water level at least 1/2 inch above
plates at all times as the evaporation is very rapid in rubber jar
cells.

The temperature should be watched on charging to prevent overheating.
Never allow temperature to go above 110 deg. F.

Unlike the glass jar cells the sediment space in the rubber jar is not
sufficient to take care of all the active material in the positive
plates. On repairs, therefore, always clean out the sediment and
prevent premature short circuits.

WESTINGHOUSE FARM LIGHTING BATTERIES

Jars. Westinghouse Farm Lighting Battery jars are made of glass, with
a 5/16 inch wall. The jars are pressed with the supporting ribs for
the elements an integral part from a mass of molten glass. A heavy
flange is pressed around the upper edge to strengthen the jar.

Top Construction. A sealed-in cover is used similar to that used in
starting and lighting batteries. The opening around the post hole is
sealed with compound.

Plates. Pasted plates are used. The positives are 1/4 inch thick, and
the negatives 3/16 inch. Posts are 13/16 inch in diameter.

Separators. A combination of wood and perforated rubber sheets is used.

Opening and Setting-Up Westinghouse Farm Lighting Batteries

[Fig. 327 Westinghouse farm lighting cell]

It is preferable that the temperature never exceed 100 deg. Fahrenheit
nor fall below 10 deg. in the place where the battery is set up. If
the temperature is liable to drop below 10 degrees the battery should
be kept in a fully charged condition.

1. Remove all excelsior and the other packing material from the top of
the cells. Take cells out carefully and set on the floor. Do not drop
or handle roughly. Be sure to remove the lead top connectors from each
compartment.

2. Cells should be placed 1/4 inch apart. Also, cells should be placed
alternately so that positive post of one cell i
