Replacement Wristwatch Batteries
Types of Watch Batteries
Watch batteries are classified into two types: silver oxide and lithium. Most watches use silver oxide batteries because they are inexpensive and dependable with a fairly long lifespan. While lithium batteries are less prevalent, they are becoming more and more common for all device types. They are more expensive, but they last longer and perform better at high temperatures.
How to Replace a Watch Battery
Replacing a watch battery simple enough to do at home with the right tools. First, you'll need to identify the type of battery your watch uses. On most batteries, you'll see a short code of letters and numbers like "CR2032". These codes refer to the materials used in the battery and its size. Once you have identified the model you need, you can purchase a replacement online from Battery Products.
What you'll need:
- A small screwdriver
- Tweezers
- A fresh battery
Using the screwdriver, remove the rear cover of your watch to expose the battery. Take care not to scratch the cover or the watch. Then, use the tweezers to remove the old battery and insert the new one. Finally, replace the back cover of the watch and screw it into place. Voilà! Your watch should be functioning like new.
