Evcready Layerbilt "B" Battery No. 486, the Heavy-Duty battery that should be specified for all loudspeaker sets.
This is the Heavy-Duty Battery inwhich the new Layerbilt construction provides greater economy
There's an important discovery in radio economy awaiting all users of loud-speaker sets who have been buying the smaller Light-Duty "B" batteries instead of the large Heavy-Duty size required by such sets. Because the Light-Duties cost somewhat less to buy they seem like an economy, but the surprising fact is that the Eveready Layerbilt No. 486 lasts more than twice as long though it does not cost anywhere near twice as much. It is, therefore, much more economical — we believe it to be the most economical "B" battery ever built. Certainly it has proved this by laboratory tests and the service ft has given to radio listeners in their own homes during the past eighteen months. Eveready Layerbilt's remarkable life
is due to its unique construction. All other dry cell "B" batteries are assembled of cylindrical cells, with much waste space between them, and many soldered connections bridging the gaps.
Several years ago we struck boldly out, away from this tradition, seeking a better method. We wanted to avoid waste space, minimize soldering, and get more current and longer life from a given quantity of active materials. The Eveready Layerbilt is the result.
This patented, exclusive battery is built in layers of flat current-producing elements, making automatic connection with each other. Every available inch inside the battery is occupied usefully. You get more battery for your money, and that battery is more efficient.
Remember this about "B" batteries: All loud-speaker sets require HeavyDuty batteries, and the Eveready Layerbilt has proved time and again, to be the longest lasting and most economical Heavy-Duty "B" battery.
