Today we use the batteries for many devices that we use in the home, on the street and at work. Many everyday objects need batteries to work properly. Batteries come in many types: AA, AAA, AAAA, C, D etc. However, for some reason on this list are missing A and B types. This study shows whether these types of batteries existed, where they previously were applied and where they are applied so far. It explains what devices worked and can still work on these kind of batteries.
What Happens to the “A” and “B” Batteries
Many appliances in our house, such as clocks, flashlights, a player, a camera, etc., run on batteries. Today, battery types, such as “AA”, “AAA”, “C”, and “D” are quite familiar to us by virtue of its distribution in our daily lives. However, it is not clear what to do with the batteries, which are designated as “A” and “B”. Indeed, it is strange that “A” and “B” are missing in a chain of the letter designations. It is hard to believe that these letters were missed by ridiculous accident or intentionally. Nevertheless, the answer is really simple.
After the World War II, there was a need of the specification, including size of batteries, the location of cells in them, tests and minimum performance criteria. First dry cell batteries have received their designation in 1924. They were named in alphabetical order, starting with the smallest cells in the volume. In 1927, this specification has been adopted as Government Standard Specification ? 58A by American Standards Association, the predecessor to the American National Standards Institute (ANSI). In these years, “A” and “B” batteries were quite common, because of the large number of radio amateurs. As standard, the A-size batteries were used to supply power for the electron tube filament. The B-size batteries were used to provide power for the electron tube plate. Today, radio is no longer distributed to consumers. However, there is a second side of the coin. The old form of batteries “A” and “B” are no longer used. However, if we take into account that the battery consists of one or more cells, also called alphabetically A, B, C etc, then in this case we can say that the “A” batteries are still applied. “A” cells are produced and used. They are combined to form larger batteries for portable lamps. Besides, “A” batteries are still using in early-model laptop battery packs. “B” cells, in turn, are completely out of use. These types of batteries just fell out of use, as instruments that used them gave a way to more versatile devices.
In the future, a number of standards will only increase with the growth of technology and the creation of new devices.
