What are the batteries for watches

Electricity has entered our lives forever. It penetrates into those devices that until recently were considered mechanical. It also entered the sphere of time measurement: the spring was replaced with accurate batteries for the clock, relieving the person of the need to start the mechanism every day.

Now, from the batteries are working and large wall clocks, and desktop alarms, and wrist chronographs. They are able to ensure the operation of the mechanism for years, but there comes a time when it is time to change them to new ones. The signal that the life time ends is a constant lag of the arrows for a few minutes a day.

What are the batteries for watches

Usually a person takes out the used battery on his own and hopes to buy exactly the same one. And very often it turns out that this is not in the store, but there are a lot of analogues. Depending on the size and design of the clock, they use finger, point (button, disc) and solar batteries.

Cylindrical batteries

They are used in wall clocks, small household appliances with the function of time display, alarm clocks. They have a different size, depending on it, they are marked as AA (R06) - fingered, and also AAA (R03) - mischievous. They are produced with salt and alkaline electrolyte. Salt cells are cheap, but they have a short shelf life, they do not work well at sub-zero temperatures. Alkaline batteries weigh more than salt and exceed them in capacity by 1.5 times. They are more expensive, they are stored longer, their service life is longer. Recently, lithium batteries have become popular: they are not cheap, but powerful, reliable, they serve at all temperatures.

Clock Button Batteries

Miniature and light, they are used in different types of electronic watches. They are divided into three types. Manganese-zinc - the most inexpensive and less capacious. Shelf life - 2 years. Oxide-silver has higher energy characteristics, stored up to 3 years. Disk lithium has a small self-discharge, stored up to 10 years. Exceptionally workable. Perfectly suitable for operation in a multifunctional wristwatch.

Energy of sun

Photovoltaic generators invented to introduce Japanese watches. Unlike other types, they are safe for the environment, also durable, reliable and light. Such a battery for watches can be charged even from a regular lamp and a scant spark of a candle. It is unfortunate that companies that manufacture watches on solar cells can be counted on the fingers. Of the well-known manufacturers it is worth noting Casio and such innovators as Citizen.

Something about quality

If we talk about quality, experts advise buying Japanese products. Their service life corresponds to the declared. These batteries for watches are very good. And very expensive.

The Chinese, producing beautiful short-lived watches, produce about the same batteries. They are not bad, their quality is quite in line with the price.

Dear producers from the country of cheese and chocolate produce under the famous brand rather average batteries, which can sometimes give a leak, spoiling the clockwork. And the products of German manufacturers are no better and no worse than their Asian counterparts.

Replacing the battery in hours

Replacing the battery in the clock - the process is not so difficult, but expensive prestigious models are best attributed to the workshop. In the watch, it's easier to change the battery by 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 gently podkovyrivaetsya, the lid is removed. Now we need to get the replacement element - a small silver tablet. It must also be carefully tucked away and taken to the nearest electronics store. Buy the same battery, and the old one for recycling.

After coming home, repeat the process in the reverse order. The battery should look upwards with the side on which the marking is stamped. The lid returns to the clock and snaps into place. The process is over.
