Electricity entered our lives forever. It penetrates into those devices that until recently were considered mechanical. It also invaded the sphere of time measurement: neat watch batteries replaced the spring, saving a person from the need to start the mechanism every day.
Now large wall clocks, desk alarm clocks, and wrist chronographs are powered by batteries. They are able to ensure the operation of the mechanism for years, but there comes a time when it is time to change them for new ones. The signal that the service life is ending is the constant lag of the arrows for several minutes a day.
What are watch batteries
Usually a person takes out a used battery and hopes to buy exactly the same one. And very often it turns out that there is no such one in the store, but there are a lot of analogues. Depending on the size and design of watches, they use finger, point (button, disk) and solar batteries.
Cylindrical batteries
Used in wall clocks, small household applianceswith the function of showing the time, alarm clocks. They have different sizes, depending on it they are marked as AA (R06) - finger, as well as AAA (R03) - little finger. Are issued with saline and with alkaline electrolyte. S alt batteries are cheap, but have a short shelf life, do not work well at sub-zero temperatures. Alkaline batteries weigh more than s alt batteries and exceed them in capacity by 1.5 times. They are more expensive, stored longer, their service life is longer. Recently, lithium batteries have become popular: they are not cheap, but powerful, reliable, and serve at any temperature.
Watch button batteries
Small and lightweight, they are used in various types of electronic watches. They are divided into three types. Manganese-zinc - the most inexpensive and less capacious. Shelf life - 2 years. Oxide-silver have higher energy characteristics, are stored up to 3 years. Disk lithium batteries have a low self-discharge, they are stored for up to 10 years. Exceptionally efficient. Perfect for use in multifunctional watches.
Sun Energy
Photoelectric generators were invented by the Japanese to introduce into watches. Unlike other types, they are environmentally friendly, durable, reliable and lightweight. Such a watch battery can be charged even from an ordinary lamp and a meager candle light. It is unfortunate that the companies producing solar-powered watches can be counted on the fingers. Of the well-known manufacturers, it is worth noting Casio and such innovators asCitizen.
A bit about quality
If we talk about quality, then experts advise purchasing products from Japanese manufacturers. Their service life corresponds to the declared. These watch batteries are very good. And very expensive.
The Chinese, who produce beautiful short-lived watches, produce about the same batteries. They are not bad, their quality is quite consistent with the price.
Respected manufacturers from the country of cheese and chocolate produce fairly average batteries under a well-known brand, which can sometimes leak, damaging the clockwork. And the products of German manufacturers are no better and no worse than their Asian counterparts.
Replacing the watch battery
Changing a battery in a watch is not that complicated, but it is better to take expensive prestigious models to the workshop. In simpler watches, you can change the battery yourself. First you need to open the case with a small screwdriver.
To do this, the clock is placed on the table with the back side up. Usually there is a recess on the back cover. It is carefully podkovyrivaetsya, the lid is removed. Now you need to get the element that needs to be replaced - a small silver tablet. It, too, must be carefully picked up from its place and taken to the nearest electronics store. Buy the same battery and recycle the old one.
When you get home, repeat the process in reverse order. The battery should look up with the side on which the marking is embossed. The cover is returned to the watch andsnaps into place. Process ended.
