Type of Quartz Watch's Battery and It's Working Life

Quartz watches , there are three main types of batteries :


1 , alkaline batteries LR

2 , silver oxide batteries SR

3 , lithium battery CR or LI

Ordinary battery voltage will gradually decrease with use , while 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 the accuracy of quartz watches have a great advantage . But the problem caused by the battery voltage can not be a simple measurement method to determine the adequacy of the battery 's power is said to now there is no quick and nondestructive equipment , to do the measurement .

Silver oxide batteries have a high current output and low current output of difference , according to watch the type of battery should be used to determine which type of order . If the watch has trouble with finder, audio features 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 , replace the battery according to the provisions of a certain type selection . Only the same size and shape to be used indiscriminately , can cause abnormal working watches , watches the lights and alarm ring of power thousands of times the normal travel time in the watch of power . To extend battery life so as to minimize the number of lights and alarm . Battery type the letters behind : The SW said that the low current output , for Analog quartz watches ; use the W , said high-current output for alarm or lighted with digital quartz watches .

Good quality batteries, surface polishing is very bright, clear marks and letter marks , its side has printed up a cluster bomb , said the production date . Fake batteries made generally coarse , fuzzy mark , and the use of very short . Comparison of the famous brand watch battery : Switzerland has "RENATA" ( which Each battery is individually wrapped ), Japan has Seiko SEIKO, the quality is good , with good quality made in Changzhou, " up to stand . " Good quartz watches have to use good quality batteries , poor battery often will watch harm .

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

Leakage , climb up the battery base and air quality problems . Internal alkaline battery electrolyte ( sodium hydroxide or potassium hydroxide ) is a serious corrosion movement , resulting in parts rust damage , ( I have a RADO watch , is due to battery leakage after the dial to the corrosion , and later spent More than 500 yuan for which the dial ) circuit barrier . Watch for battery power and stop and go , or long-term storage of unused , 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 phenomena , high humidity and temperature of the environment will increase the battery self-discharge , when placed in cold storage and dry conditions. Unused for long periods to pull out the watch to watch ( do not watch the second needle ), the battery temperature below 0 ℃ , the battery current output will become very weak , with lights and alarm sound and a digital display window Quartz watches, these functions should be affected.

Silver oxide battery will not charge or broiled, when installed in the store and by , be careful not to cause short circuits. Watch repair shop of used batteries should focus in order to prevent contamination caused by pollution.
