What is an hour battery?
Watch battery is a small battery with a form commonly used in such small electronic devices as wrist watches, hearing aids, laser indicators, long -distance drivers of the keyless inputs and calculators with small pockets. They are also called button cells, silver button cells or coin batteries. The tracking battery is usually one cell with a nominal voltage in the range of 1.5 to 3 volt. Due to its extremely small size, the Watch battery has an extremely long life. This coding system consisting of a three -to -five code is partially based on an electrochemical system used in the battery. The encoding system also describes the diameter and height of the battery and the shape of the battery cover. One of the most commonly used watch batteries is C-type battery. This 3-volt lithium battery is used not only in Křemeneches, but also in some personal data assistants (PDA), as well as in the motherboard computer hours. They are not commonly used because their charging capacity isLower than non -proechargable batteries and tend to drain much faster. In addition, tracking batteries are used in devices where energy consumption is so low that there is no tangible benefit when recharging. In many cases, the Watch battery actually survives a device that has been aimed at power.
Most of the batteries that are commonly used today are either zinc or silver -oxide batteries. The mercury -based button cells, once very popular as a watch, are now banned in many countries because of concern for their impact on the environment. This ban has caused a special problem for photographs. Much of their sensitive equipment still relies on a very surface, stable discharge curve and long life of mercury cells.
Photographers have come to replace mercury batteries with zinc-air batteries that have a similarly flat curveFlow on mercury cells, but much shorter life. Zinc air batteries also work poorly in a very arid climate, which applies to some photographers. Another alternative for mercury cells is the batteries of alkaline watches, but their tension changes so wide during the battery life that photographers do not like them. Best-the most expensive-alternative for photographers are silver oxide batteries. They have a more acceptable flat discharge curve, albeit less flat than mercury.
Care must be devoted to the requirements for the battery of any device using the Watch battery. The use of the wrong type or the voltage of the button cells can not only destroy the device, but can also be a striking risk. The manufacturer's instructions should always be followed in a letter to ensure the safe and efficient operation of the equipment.
