Understanding Watch Batteries: A Comprehensive Guide
To prevent you from damaging your favorite watch, it is important to know about watch batteries. The battery in a watch is usually small, also called a button cell, cell battery, button battery, or coin battery. The battery life is typically between 2 to 5 years, with higher-quality batteries lasting up to 5 years. Watches that require a battery are either quartz or electronic watches (smartwatches).
Types of Watch Batteries
There are three main types of batteries used in watches:
- Mercury Battery
- Silver Oxide Battery
- Lithium Battery
Each type has its unique characteristics and applications, making it essential to choose the right one for your watch.
Technical Features Comparison
| Feature | Mercury Battery | Silver Oxide Battery | Lithium Battery |
|---|---|---|---|
| Voltage | 1.35V | 1.55V | 3V |
| Capacity | Low | Moderate to High | High |
| Lifespan | 1-2 years | 2-5 years | 5-10 years |
| Environmental Impact | Toxic | Less toxic | Non-toxic |
| Common Uses | Older watches | Most quartz watches | Digital watches, cameras |
Types of Watch Batteries Comparison
| Battery Type | Description | Common Models |
|---|---|---|
| Mercury Battery | Contains mercury, now largely banned due to toxicity. | N/A |
| Silver Oxide Battery | Provides stable voltage, commonly used in quartz watches. | SR626SW, SR920SW |
| Lithium Battery | High energy density, used in modern digital devices. | CR2032, CR2025 |
Understanding Battery Designations
The model number of a watch battery is usually an identifier consisting of a string of numbers and letters. Different watch models require different battery models. The most common watch battery model on the market is the SR626SW, also known as the 377 battery.
What Do the Codes Mean?
- Prefix Letters: Indicate the type of battery.
- BR or CR: Lithium Battery
- SR or SG: Silver oxide cells
- LR or A: Alkaline batteries
- M: Mercury oxide (not allowed now)
- Suffix Letters: Indicate the electrolyte used.
- SW: Low drain type for quartz watches.
- W: High drain type for all quartz watches.
Choosing the Right Battery
When replacing a watch battery, it’s crucial to select the correct type based on the watch’s specifications. For example, a watch with a backlight may require a high-drain battery, while a standard analog watch can use a low-drain battery.
Battery Replacement Process
If you need to replace a watch battery, you can follow these steps:
- Remove the Back Cover: Use a case opener to access the battery.
- Identify the Battery Type: Read the serial number on the battery.
- Purchase the Correct Battery: Ensure it matches the specifications of your watch.
For those uncomfortable with DIY replacements, professional services like Total Watch Repair offer expert assistance.
Environmental Considerations
When disposing of batteries, it’s essential to distinguish between types. Alkaline batteries (LR) can be disposed of in regular trash, while lithium (CR) and silver oxide (SR) batteries should be recycled properly due to their hazardous materials.
Conclusion
Understanding the different types of watch batteries and their specifications is crucial for maintaining your timepiece. Whether you choose a silver oxide battery from Renata or a lithium battery from Microcell, ensuring compatibility with your watch is key. For repairs, consider professional services like Total Watch Repair or consult resources like Ohlala Watch for guidance.
