Quartz watch batteries and battery life

Quartz watch battery type about in three ways:

1, alkaline batteries LR
2, silver oxide battery SR

3, lithium battery CR or LI

Is currently the most used button silver oxide battery, silver oxide battery is characterized by small size, large capacity, and the output voltage stability. Cell size range, small diameter of only about 4mm, the thickness of about 1mm; large diameter 11mm, thickness of about 5mm. Battery international model also reflects its actual size, such as: common SR626 type of battery, is the diameter of about 6mm, 2.6mm thickness of the battery.

Ordinary dry battery voltage will gradually decrease with use, and silver oxide battery voltage only when the end of the fast life, the voltage will suddenly drop, the characteristics of the travel time to ensure accuracy of quartz watches, a great advantage. But the problem is not caused by a simple method of measuring the battery voltage to determine the adequacy of the battery is said to now there is no quick and non-destructive instrument, to do the measurement.

Silver oxide batteries have a high current output and low current output of the difference, according to the type of watch used to determine which type of battery should be. If the watch has trouble with Xiao Zhao sound function or light, on the application of high currents. (Such as figures show that the quartz watch) most of the quartz watch is a low current, the battery must be replaced according to the provisions of model selection. Only the same size and shape to be used indiscriminately, can cause malfunction of the watch, watch the lights and the sound of the power consumption of trouble in the table thousands of times the power consumption of the normal travel time. Therefore, in order to extend battery life, minimize the number of lights and buzzers. Battery Type the following letter: The SW said that the low current output for Analog quartz watches; with the W, said the high current output for trouble or illuminated with digital quartz watches.

Good quality batteries, surface finish is very bright, clear imprint marks and letters, printed up on its side of the picture, indicating date of manufacture. Fake batteries made generally coarse, blurred imprint, and with a very short period. Watch battery more well-known brands: Switzerland has "RENATA" (which Each battery is individually wrapped), Japan has Seiko SEIKO, are good quality, made of good quality have Changzhou "Talib." Be sure to choose good quality quartz watches good battery, poor battery often will bring harm to the watch.

Battery life and two factors: 1, the battery itself, capacity, battery capacity, the greater the power the smaller the longer service life. 2, watch the size of the circuit power consumption, power consumption is now about quartz watches in about 1 μA, the battery capacity of about 4 ~ 40 MAH, Li-ion battery capacity to a larger point. In general, the smaller the watch battery is also smaller, the smaller capacity, the use of short duration; two needles watch more than three needle or pointer battery durability. In any case, under normal use the battery at least use more than one year guarantee period. If the watch appears frequently replace the battery, it should consider whether there is failure of the circuit.

Leakage, climb up the battery alkaline gas quality problems. Internal alkaline battery electrolyte (sodium hydroxide or potassium hydroxide) movement will be severe corrosion, rust damage caused by parts, (I have a RADO table, is due to battery leakage and corrosion after the dial to, and later spent 500 yuan for which the dial) circuit barrier. Watch battery is dead and because of stop and go, or do not have the long-term storage, remove the battery as possible to prevent battery leakage and gas up. According to statistics, there is a failure of the quartz watch is mostly caused by the battery. So, when you need to replace watch battery, be sure to select high-quality batteries, but also to the reliable watch repair shop to replace.

Silver oxide battery is not even have the self-discharge phenomenon, humid and high temperature conditions will increase the battery self-discharge, when placed in cold storage under dry conditions. Long-term use of the watch to pull out the table (do not have to watch two needles), the battery temperature below 0 ℃, the battery current output will become very weak, with lights and sound the alarm and digital display window quartz watches, these functions should be affected.

Silver oxide battery will not charge or roasted in the store and installed by, careful not to cause a short circuit. Watch repair shop used the old batteries should focus in order to prevent pollution caused by pollution.
