Nowadays quartz watches usually have a battery life indication feature. When you buy a watch you should notice the date of the next battery change indicated on the sticker on the back cover, but generally the actual battery life is longer. If the date is not clearly marked, you can replace the battery when:
1.
1. The watch suddenly appears to go slowly or stop on and off
When the battery power drops and the capacity is insufficient, the internal resistance of the battery also increases and the voltage drops, especially when there is a relatively high current output or when the outside temperature is low, the watch will stop or suddenly appear to go slow or stop on and off. 2. The digital display of the watch is dull, and the digital display disappears when there is an alarm function. The on light and alarm functions of a watch with digital display are particularly power hungry. If the digital display becomes dim or even disappears when the light and alarm are on, it is time to change the battery.Warm reminder: The latest market news is always available, please follow LuFuture.com app.
