Watch battery with mA-hour capacity (maH) that, depending on battery size, the general capacity of silver oxide battery is in a few milliamperes to a few dozen milliamperes between the size of the larger capacity is more Great. Watch the power circuit are microamp level, the current level of IC circuits can be done about a microampere. Theoretically, the battery life equivalent to battery capacity divided by the circuit power consumption.
Watches used in the most conventional silver oxide battery is the battery, it has small size, large capacity and stable discharge characteristics. In other words, silver oxide battery will not like an ordinary dry-cell batteries, the voltage will gradually decrease with the use. Silver oxide battery model specification is very large, there are dozens of kinds of bar, with the more common in Japan, the brand are: Panasonic, Sony, Maxell, Seiko, etc., produced in Switzerland is called “RENATA”, It is independent of the battery packaging.
From the use of the situation, RENATA batteries more expensive, more refined appearance, but it seems that the battery sealing performance is not as good as Japan’s, climbing base occurred from time to time, all the Swiss watches are quartz with Renata, and Japan Seiko brand of batteries for the best. Need to know, even with a battery specifications, different manufacturers are not the same battery capacity, there is a silver oxide battery indicator tables, which are given all the battery voltage, size and capacity of the detailed data.
Quartz watches now circuit are variable width, and the circuit of the circuit power consumption is directly related to the output pulse width, pulse width the greater the power consumption is greater, usually watches the calendar for the time or place when the vertical position, circuit to the stepper motor pulse output will become larger, so take off the watch at night must do it horizontal.
Any semiconductor silicon materials are sensitive to temperature, the higher the temperature, the greater the current. Therefore placed in a watch can not be long-term Heating near any heat source and place.
Any semiconductor silicon materials are sensitive to light, especially sunlight, especially in liquid crystal display or LCD + indicators Display Type represented by the quartz watch, because light may be transmitted to the watch circuit, so increasing the possibility of circuit power consumption Therefore, to avoid long-term exposure to watch the sun strong following.
Humid environment on the quartz watch against relatively large, because there is no absolute sealed watch, once the water vapor or moist air to enter the watchcase inside, depending on the extent of serious corrosion of steel parts will be at the very least, a great increase in watches circuit power consumption.
Where there are electric pointer adjustment, with trouble, with light, elevation, temperature, etc. Guide to the watch Additional features should minimize the use of the frequency, in particular to make sound and lighting features, it is thousands of times the power consumption of large watch in normal power consumption.
Therefore, when the battery replacement is necessary to pick a good quality brand batteries, pay attention to peacetime environmental requirements to wear watches. There is no doubt that the only way to make the battery life was extended.
