Type "F" Batteries

There is only one type "F" battery. It is of big heavy construction exactly the same dimensions as the battery used for a number of years on the Cadillac and certain other cars. This battery is heavier than type "C" of the same capacity and it has a greater life.

WILLARD BATTERIES

Since 1912, when the Willard Storage Battery Co. began to manufacture storage batteries for starting and lighting work, various types of Willard batteries have been developed. The original Willard starting and lighting batteries used two-piece, or "double" covers. These are shown in the cuts used to illustrate the sealing of double-cover covers in the preceding chapter, and no further description will be given here. The doublecover batteries are no longer made, but the repairman will probably be called upon to repair some of them. The instructions given in the preceding chapter should be used in making such repairs.

Following the double cover batteries came the single cover battery, of which a number of types have been made. One type used a rectangular post, and was very difficult to repair. Fortunately, this type was not used extensively, and the battery is obsolete.

Willard Batteries With Compound Sealed Posts

The oldest type single-cover Willard battery which the repairman will be called upon to handle is the compound sealed post type, illustrated in-Fig. 277. This battery includes types SEW, SER, SJW, SL, SLR, SM, SMR, STR, SXW, SXR, SP, SK, SQ, EM, and EMR. As shown in Fig. 277, there is a well around each post which is filled with: sealing compound. On the under side of the cover is a corresponding well which fits into the post well, the sealing compound serving to make the seal between the cover and the post.
