Vesta Radio Batteries. Fig. 160 shows the 6EA Series, ”A” Battery.

Fig. 161 shows the V6EA Series, ”A” Battery. Fig. 162 shows the R6EA (Rubber Case) Series, ”A” Battery. Fig. 163 shows the ”B” Battery.

These batteries have 5, 7, 9 plates per cell, respectively. The plates are each 5 inches high, 5 7/8 inches wide, and 5/32 inches thick. The cases for these batteries are furnished in three designs--plain black boxes (all sizes), finished maple boxes (7 plate size only), and hard rubber boxes (9 plate size only). These Vesta batteries are the ”A”

batteries used for heating the filaments of the audion bulbs. The Vesta Radio ”B” battery, Fig. 163, is a 12 cell, 24 volt battery, with a 22 and a 20 volt tap.

EXIDE RADIO BATTERIES

[Fig. 164 Exide Radio ”A” battery]

The Exide Radio ”A” battery, Fig. 164, is made in four sizes, the capacities ranging from 20 to 120 ampere-hours. The design and construction of these batteries are similar to the Exide starting batteries. The over-all height of these batteries is approximately 95/8 inches, the width 7-5/16 inches, while the length varies with the number of the plates.

Type Cat. No. Length Weight Capacity -------- -------- ------ ------ -------- 3-LXL-3 13735 4-9/16 15-1/2 lbs. 20 amp. hrs.

3-LXL-5 13736 5-11/16 24-1/2 lbs. 40 amp. hrs.

3-LXL-9 13737 9-1/16 42-1/2 lbs. 80 amp. hrs.

3-LXL-13 13750 12-7/16 59-1/2 lbs. 120 amp. hrs.

WILLARD RADIO BATTERIES

The Willard Storage Battery Co. manufactures both ”A” and ”B” storage batteries. The Willard ”A” battery, Fig. 165, is an all-rubber battery. The case is a rubber ”Mon.o.bloc” construction, that is, the entire case is pressed into shape at one time. There are no separate jars for the cells, there being rubber part.i.tions which form integral parts of the case. The case is, therefore, really 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 b.u.t.ton 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 gla.s.s 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 a.s.sembled 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.
