(1) the capacity of the battery, (2) Power consumption of the watch movement circuit. The larger the battery capacity, the lower the power consumption of the circuit, and the longer the battery life. The capacity unit of the watch battery is expressed in milliampere hours (maH). Depending on the size of the battery, the capacity of the general silver oxide battery is between several mAh and several tens of milliamperes. The larger the volume, the larger the capacity. Big. The power consumption of the watch circuit is micro-ampere, and the current IC circuit level can be about 1 microamp. Theoretically, battery life is equal to battery capacity divided by circuit power consumption. The most popular battery for watches is the silver oxide battery, which has the characteristics of small size, large capacity and stable discharge. That is to say, the silver oxide battery does not gradually drop in voltage as the ordinary dry battery. There are many models of silver oxide batteries, there are dozens of them, which are more common in Japan. The brands are: Panasonic, Sony, Wansheng, Seiko, etc. The Swiss is called "RENATA", its battery They are all individually packaged. From the point of view of use, RENATA's battery is more expensive and the appearance is more delicate, but the battery sealing performance does not seem to be as good as that of Japan. The phenomenon of climbing alkali occurs all the time. All Swiss quartz watches are made of RENATA, made in Japan. The battery is best with the Seiko brand. Be aware that even the same battery size, the battery capacity of different manufacturers is not the same, there is a table of indicators on the silver oxide battery, which gives detailed data on the voltage, size and capacity of all batteries. The current quartz watch circuit is variable pulse width, and the power consumption of the circuit has a direct relationship with the pulse width output. The larger the pulse width, the greater the power consumption. Usually, when the watch is placed in the calendar or in the vertical position, The pulse output of the circuit to the stepping motor will become larger, so it is necessary to place it horizontally at night to take off the watch. Any semiconductor silicon material is sensitive to temperature, and the higher the temperature, the greater the operating current. Therefore, the watch cannot be placed near the heater for a long time, and there is any heat source. Any semiconductor silicon material is sensitive to light, especially sunlight, especially represented by a liquid crystal display or a quartz watch with a liquid crystal display + pointer display type, because light may be transmitted to the watch circuit, which may increase the power consumption of the circuit. , so avoid long-term exposure of the watch to strong sunlight. The damp environment is more harmful to quartz watches because the watch is not absolutely sealed. Once the moisture or humid air enters the case, depending on its extent, serious corrosion of the steel parts will at least greatly increase the watch's The circuit consumes power. Watches with additional functions such as electric hand adjustment, belting, lighting, altitude, temperature, guide, etc. should minimize the number of uses, especially the noise and lighting functions, which consume thousands of times of electricity. Greater than the normal power consumption of the watch. Therefore, when replacing the battery, it is necessary to pick a good quality battery, pay attention to the environmental requirements of wearing the watch. Undoubtedly, the only way to extend the battery life is.

How to extend the life of quartz watch battery
The battery life of a quartz watch depends mainly on two factors:
