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.

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.

[Fig. 165, 166, and 167 Various Willard Radio Batteries]

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.

WESTINGHOUSE RADIO BATTERIES

[Fig. 168 Westinghouse Radio "A" battery, Type HR]

[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 s.p.a.ce, 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.

The Westinghouse Radio "B" batteries are made in two sizes. Type 22-M-2, Fig. 170, has a capacity of 1.2 ampere hours at 0.04 ampere.

It is designed to operate a receiving set having one detector and two amplifier bulbs for three to five weeks between charges. The type 22-L-2 battery, Fig. 169, has a capacity of 4.5 ampere hours at 0.25 ampere.

PHILADELPHIA RADIO BATTERIES

[Fig. 171 Philadelphia Radio "A" battery]

The Philadelphia Storage Battery Co. makes both "A" and "B" Radio batteries. The "A" battery, Fig. 171, uses the standard diamond-grid plates, and the "Philco Slotted Retainer" used in Philadelphia starting batteries. The cases of the "A" batteries are made of hardwood, finished in an ebonite black. Soft rubber insulating feet on the bottom of the case prevent scratching any table or varnished floor on which the battery may be set. The instructions for preparing the Philadelphia "A" battery for service are similar to those given for the starting and lighting batteries, given on page 228. For the initial filling, 1.220 electrolyte is used, and the battery charged at the following rates:

Initial and Recharge Charging Rate ------- Type Initial Rate Recharge Rate ---- --- ---- 56LAR 1.0 2 56RAR 2.0 3 76RAR 3.0 4.5 96RAR 4.0 6 116RAR 5.6 7.5 136RAR 6.0 9

The final gravity of the electrolyte should be 1.250. However, if the owner insists on getting maximum capacity, the battery may be filled with 1.250 electrolyte and balanced to 1.290 at the end of the charge.

[Fig. 172 Philadelphia Radio "B" battery]

The Philadelphia Radio "B" battery, type 224-RB, Fig. 172, has 12 cells contained in a one-piece rubber case. It is s.h.i.+pped dry, and requires no initial charge. To prepare it for service, the soft rubber vent caps are removed and 25 c. c. of 1.250 electrolyte poured into each cell.

U. S. L. RADIO BATTERY

[Fig. 173 U.S.L. Radio "A" battery]

The U. S. L. Radio "A" battery, Fig. 173, uses 1/4 inch positives, with 3/16 inch intermediate and 1/8 inch outside negatives. Port Orford cedar separators are used which are four times as thick as the usual starting battery separator. The case is made of hardwood, and is varnished to match cabinet work. The electrolyte has a specific gravity of 1.220. The heavy plates and separators and the low gravity of the electrolyte are designed to give long life.
