How to extend the battery life of a quartz watch?

How to extend the battery life of a quartz watch The battery life of a quartz watch depends on two factors: (1) battery capacity and (2) power consumption of the watch movement circuit. The larger the battery capacity, the smaller the circuit power consumption, and the longer the battery life. The battery capacity unit of the watch is milliampere hour (maH). According to the size of the battery, the capacity of the silver oxide battery is generally between several milliamperes to tens of milliamperes. The larger the capacity, the greater the capacity. The circuit power consumption of the watch is microampere level, and the level of the IC circuit can be about 1 microampere level. In theory, the battery life is equal to the battery capacity divided by the power consumption of the circuit. The most popular battery for watches is silver oxide battery, which has the characteristics of small size, large capacity and stable discharge. In other words, silver oxide batteries will not be the same as ordinary dry batteries, and the voltage will gradually drop with use. There are many types of silver oxide batteries, and there are dozens of them. Among them, they are more common with Japanese processing. The brands are: Panasonic, Sony, Mansheng, Seiko, etc. The Swiss processing is called RENATA, and the battery is individually packaged. The usage of RENATA batteries is more expensive and the appearance is more beautiful, but the battery sealing function seems to be inferior to Japan, and the phenomenon of alkali climbing from time to time, all Swiss quartz watches are made by RENATA Japanese battery Seiko brand is the best. You should know that even if it is the same standard battery, the battery capacity of different manufacturers is not the same. There is an index table for silver oxide batteries, which gives specific data on the voltage, ratio and capacity of all batteries. Now the variable pulse width of the quartz watch circuit, the pulse width and the power consumption of the circuit output have a direct relationship, the pulse width, the greater the power, the more the vertical bearing generally looks at the calendar time or location, the stepper motor pulse output circuit will become It's bigger, so taking off the watch at night will definitely put it on the level. Any semiconductor silicon material is very sensitive to temperature, 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 very sensitive to light, especially sunlight, especially the liquid crystal display may be a liquid crystal display + pointer type quartz watch as a representative. Because the circuit may be transmitted by light, it is possible to increase the power consumption of the circuit, so for Take precautions against prolonged exposure to strong sunlight. A humid environment is more harmful to quartz watches, because the watch is not sure whether it is sealed or not. Once humid or humid air enters the case, depending on its degree, the steel parts that will rust seriously will at least greatly increase the function of the watch circuit. Consumption. Watches with electric pointer adjustment, noise, light, altitude, temperature, strategy and other additional functions should be minimized, especially the functions of noise and light, whose power consumption is thousands of times the normal power consumption of the watch. Therefore, the replacement of the battery is to choose a good brand and good quality battery, and pay attention to the environmental requirements of wearing the watch at ordinary times. There is no doubt that the only way to extend battery life. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
