e plates per
cell than the usual 1/8 inch plate battery. It has the same number of
plates as the 3/32 inch thin plate battery, but the thickness of the
plates is about half-way between the 1/8 inch and 3/32 inch plates.

The Westinghouse negative grids, Fig. 276, have very few and small
bars, just enough to hold the active material. It is slightly thinner
than the positive but has the same amount of active material, due to
the design of the grids. The condition of Westinghouse negatives
should not be determined by cadmium readings as these plates may be
fully charged and yet not give reversed cadmium readings.

Aside from the special instructions given for the Westinghouse Post
Seal, the Standard Instructions for Rebuilding Batteries, given on
pages 328 to 374 may be used in rebuilding Westinghouse batteries.

TYPES OF WESTINGHOUSE BATTERIES

Type "A" Batteries

The type "A" series was designed to fit the battery compartment in
certain rather old models of cars. Owing to a lack of space this
series is not of as efficient design as the "C" and "B" series. It
does have the Westinghouse Post Seal, however.

Type "A" batteries are not recommended for use when "B" or "C"
batteries can be used.

Type "B" Batteries

The type "B" series of batteries has been designed for use on a number
of cars now in service that do not have a sufficient headroom in the
