How to identify quartz watches that need to be replaced by batteries? Predict in advance that our quartz watch is about to change batteries, but also to prevent once the battery power is exhausted, watch stops and brings us trouble in wearing and using. So how do you know to change batteries for quartz watches? Let's follow Xiaobian.




How to identify quartz watches that need to be replaced by batteries? Predict in advance that our quartz watch is about to change batteries, but also to prevent once the battery power is exhausted, watch stops and brings us trouble in wearing and using. So how do you know to change batteries for quartz watches? Let's follow Xiaobian.




1. Quartz watches now generally have battery life indicators.


Three-needle (or second-hand) quartz watches basically have battery life indicator function. When the battery capacity is about to run out and the voltage starts to drop, the second-hand will stop for 4 seconds, then jump for 4 seconds rapidly. (In the early stage, the watch stopped for 2 seconds, then jumped for 2 seconds.) This function is called E.O.L (BATTERY END-OF-LIFE INDICATION). When this happens, the batteries must be replaced in time, during which the watches can be transported for about a week to half a month. (Two-needle quartz watch does not have this function)




2. The date of the next battery change is indicated on the dry glue of the back cover of imported watches when they are purchased.


When you buy a watch, you should pay attention to the date of the next battery change indicated on the dry glue on the back cover, but usually the actual life of the battery will be longer.




3. The watch suddenly slows down or stops every now and then.


When the battery power drops and the capacity is insufficient, the internal resistance of the battery will also increase and the voltage will drop. Especially when the current output is relatively large or the external temperature is relatively low, the watch will stop or suddenly slow down or stop from time to time.




4. Watches with digital display show dim display, and digital display disappears when there is a loud noise.


The power consumption of the watch with digital display is very high. If the LCD digital display darkens or even disappears when the light and noise are turned on, it means that the battery should be changed. By the way, replacement batteries should be replaced by prototype numbers as required, and no attempt should be made to restore the power of old batteries by charging or baking. If the watches always need to change batteries frequently, it is necessary to check whether there is a problem with the watches'circuit.
