THOUSANDS of people have made the discovery that Eveready "B" Batteries, when used in the proper size, and on sets equipped with a "C" battery*, are a most economical, reliable and satisfactory source of radio current.
Here is the secret of "B" battery economy, reliability and satisfaction:
On all but single tube sets -Connect a "C" battery*. The length of service given below is based on its use.
On 1 to 3 tubes — Use Eveready No. 772. Listening in on the average of 2 hours daily, it will last a year or more.
On 4 or more tubes—
*NOTE : A "C" battery greatly increases the life of your "13" batteries and gives a quality of reception unobtainable without it. Radio sets mav easily be changed by any competent radio service man to permit the use of a "C" battery.
Use the Heavy-Duty "B" Batteries, either No. 770 or the even longerlived Eveready Layerbill No .486. Use Jon the average of 2 hours daily, these will last 8 months or longer.
These figures are based on the average use of receivers, which a country-wide survey has shown to be two hours daily throughout the year. If you listen longer, of course, your batteries will have a somewhat shorter life, and if you listen less, they will last longer.
Evereadys give you their remarkable service to the full only when they are correctly matched in capacity to the demands made upon them by your receiver. It is wasteful
