eally a solid, one piece,
three compartment jar. The ribs at the bottoms of the compartments are
parts of the one-piece block, and are higher than those found in the
usual starting and lighting battery. Embedded in each side wall of the
case is a bronze button which holds the handle in place. Soft rubber
gaskets of pure gum rubber surround the post to make an acid proof
seal to prevent electrolyte from seeping from the cells. The
separators are the standard Willard "Threaded Rubber" separators.

Willard Radio Batteries. Fig. 165 shows the All-Rubber "A" Battery.
Fig. 166 shows the complete "B" Battery. Fig. 167 shows one cell of
the "B" Battery.

The Willard "A" battery comes in five sizes, type WRR97 (20 ampere
hours capacity), type WRRO (50 ampere hours capacity), type WRR1 (89
ampere hours capacity), type WRR2 (100 ampere hours capacity), and
type WRR3 (125 ampere hours capacity).

The Willard "B" storage battery, type CBR124, Figs. 166 and 167, is a
twelve cell battery, each cell consisting of a round glass container
having one negative and one positive plate insulated from each other
by a small "Threaded Rubber" separator. The plates and separators rest
on a hard rubber "bottom rest" which consists of a short length of
hard rubber tube, so formed as to support the plates and separators
and at the same time hold them together. The cells are assembled in a
case which has a separate compartment for each cell. As seen from Fig,
166, the upper parts of the cells project above the top of the case,
which simplifies inspection.

WESTINGHOUSE RADIO BATTERIES

[Fig. 169 Westinghouse Radio "B" battery, Type L, and
Fig. 170 Westinghouse Radio "B" battery, Type M]

The Westinghouse Union Battery Co. manufactures both "A" and "B"
storage batteries. Their "ER" type, Fig. 168, is the "A" battery, and
their "L" and "M" types, Figs. 169 and 170, are the "B" batteries. The
HR battery has 3/16 inch thick plates, high rests to provide ample mud
and acid space, and thick separators. Rubber sheets are placed on both
sides of the positive plates. Rubber covered cables are moulded into
the terminals to minimize corrosion at the positive terminal. The "HR"
batteries are made in six and eight volt sizes, with 3 plates per
cell, 5 plates per cell, 9 plates per cell, and 13 plates per cell.
