Technique works on the network adapters, zealous owners use batteries, but all the same number of different batteries is so high that the choice sometimes turns into a flour. This partly contributes to appropriate advertising 'storm'. Commercials, colorful brochures, magazine articles breathlessly touted certain batteries and power supplies, using plenty of superlatives. Stunned and blinded by the mass lost and the buyer often chooses for himself batteries, not based on technical parameters, and suitable price. But the expensive batteries are not always the best and the cheapest is not always the worst. It confirmed by tests, both domestic and foreign independent research. Actually, strictly speaking, the name of 'batteries' are not entirely correct, more precisely – 'galvanic cell', but in everyday speech is rarely using the correct technical terms. Often translated from foreign languages do those who do not have the technical (professional) language.
The total number of basic concepts and parameters and their abbreviations in power supplies for domestic radio is small. They recommended the International Electrotechnical Commission (IEC) and the underlying standards of various countries. Terminology manufacturers is much more extensive, and the root cause of this is primarily a desire to dissociate itself from its competitors, giving their minor improvements shade of novelty and originality, to win the market and pocket the buyer. Familiar with correct terminology and other theoretical issues and technical specifications can and must be in reference books. By the way, you'll find such an important characteristic of a galvanic cell (hereinafter GE), as Capacity – inverters. Knowing the capacity and power consumption, you can see the duration of the ET of a particular manufacturer and choose the most suitable. History of the ET comes from the Italian scientist Luigi experiments Galvani held since 1780 A. Volta, the world's first GE with electrodes made of copper and zinc and use as an electrolyte solution of sulfuric acid (at the turn of 1799 and 1800), put the electricity in the service of man there which still could not reach the wire plants.
And in recognition of A. Volta is now in the International System of Units SI voltage measured in volts. How to choose the right ET, and in the presence of known species share of confusion. This is due to different standards. Hear other arguments on the topic with Don Slager. For example GE used as a power source for the player (uninterruptible power supply) could be labeled as part of AA on the U.S. Standard ANSI (American National Standards Institute) or R6 – designation, as recommended by the IEC. In the domestic GOST such an element is referred to as A-316. There are also refer to UM, AM3 and commercial name MIGNON. Such the situation for the rest of the ET occurring in the market. A little easier choice is that the device itself and / or in the manual to it always specified size to use the power supply. Except sizes, different electrochemical ET system, which, in general, and defines parameters such as capacity, shelf life, etc. In the domestic market, the most common manganese-zinc ET, and depending from use of the electrochemical system, they are divided into salt, chloride and alkaline. In all three types of electrodes are used as zinc and manganese dioxide.
