All of the "U" size batteries have been changed to Type "D," so that
all "CU" types are superseded by corresponding "DU's." Type "D" will
not be used on cells of sizes "L," "H," or "A", all of which remain of
the "C" or three-piece isolator construction. Type "S" remains old
style as before.

Type "DJ"

The Vesta Company has added a new plate size, produced in the "D"
style (one-piece) isolator only, and known as "DJ."

This plate is one-half inch higher than the "U," as shown in Fig. 267.
It has 10 per cent more capacity. "DJ" batteries are available in all
forms corresponding with "CU" types, and can be obtained by merely
changing the type form name in ordering, as for example, to replace
form 150, 6-DJ11-Y-150. The overall height of the completed battery
is, of course, one-half inch more, and the "DJ" should therefore be
ordered only when this additional height space is available in the
battery compartment of the car.

Vesta Separators

The Vesta separators, or "mats," are treated by a special process. The
Vesta Company considers its "mats" a very important feature of the
battery. See page 15.

Vesta Post Seal

A lead collar fits over each post to hold the cover tight against the
soft rubber gasket underneath. This collar is not screwed or burned on
the post, but is simply pressed down over the post, depending for its
holding power upon the fact that two lead surfaces rubbing against
each other tend to "freeze," and unite so as to become a unit. The
connector rests upon the upper race of the collar, and also helps to
hold it down in its proper position. Fig. 270 shows the complete
battery with the lead collar, and the large vent plug.

In rebuilding Vesta batteries having the lead collars, the cover
should be left in place when working on the plates, if possible. If,
however, it is necessary to separate groups, and the lead collars must
be removed, this is done as shown in Fig. 271. A few blows on the side
of the collar with a light, two ounce hammer expands the lead collar
several thousands of an inch so that the collar may be removed.

In replacing the covers, the lead collar must be forced down over the
post, and special pressure tongs are required for this
