The Classification of Quartz Watch Battery | When to Replace the Battery?

The use of quartz crystals in watches is a modern invention. The first quartz watch appeared for the first time in 1969. During this year, the Japanese company Seiko discovered how to make a tuning fork from quartz. Just like a tuning fork will vibrate in a certain way, when the quartz crystal is affected by battery power, it will also vibrate regularly; what are the classifications of quartz watch batteries? How long does it take to change the battery?

Ⅰ. Classification of quartz watch batteries

1. Alkaline battery LR;

2. Silver oxide battery SR;

3. Lithium battery CR or LI.

The best is of course the silver oxide battery. Compared with the ordinary dry battery, the voltage will gradually decrease with use, and the voltage of the silver oxide battery will drop suddenly only when the life is about to end. This feature is very important to ensure the accuracy of quartz watches. great benefit.

Moreover, the silver oxide battery has the difference of high current output and low current output. It is necessary to judge which type of battery should be used according to the type of watch. If the watch has an alarm function or has a small light, use a high current (such as a digital display quartz watch). Most quartz watches use high current, and the replacement battery must be selected according to the specified model.

Casual use only because of the same shape and size will cause the watch to work abnormally. The power consumption of the watch's lights and alarms is thousands of times the power consumption of the watch when it is running normally. Therefore, in order to prolong the battery life, try to reduce the number of lights and alarms. Letters behind the battery model: SW for low current output for analog quartz watches; W for high current output for charged or illuminated digital quartz watches.

Ⅱ. When to change the battery of the quartz watch?

The battery life of a quartz watch ranges from one year to ten years. In order to avoid a sudden power failure, a quartz watch will generally warn before the power is almost exhausted. Although the battery is dead, Longines will continue to go, but it is recommended to replace the battery as soon as possible. In general, when the second hand of an analog quartz watch jumps two spaces at a time, it means that the battery is running out of power. The digital display electronic watch will use a flashing display panel to indicate that the battery is dying.

The above is all about the battery classification of the quartz watch and when the battery can be replaced in the quartz watch. If you want to know more about the watch, you can follow our company. If necessary, welcome to consult.
