How Cell Battery Sizes Work
Cell batteries are typically identified by a code that includes the battery's size, chemistry, and voltage. The size of the battery is indicated by the first two digits of the code. For example, a CR2032 battery is a lithium coin cell battery that is 20 mm in diameter and 3.2 mm thick.
The chemistry of the battery is indicated by the letters that follow the size code. The most common types of cell batteries are alkaline, silver oxide, and lithium. Alkaline batteries are the most common type of battery and are typically used in devices such as remote controls, flashlights, and toys. Silver oxide batteries have a longer lifespan than alkaline batteries and are typically used in watches and calculators. Lithium batteries are the most powerful type of cell battery and are typically used in devices such as cameras and laptops.
The voltage of the battery is indicated by the last digit of the code. The most common voltages for cell batteries are 1.5 volts and 3 volts. 1.5-volt batteries are the most common type of battery and are used in devices such as AA, AAA, and C batteries. 3-volt batteries are less common than 1.5-volt batteries and are typically used in devices such as watches and calculators.
How Cell Battery Sizes Work with Watches
Watch batteries are a specific type of cell battery that is designed to be used in watches. Watch batteries are typically small and round, and they are often referred to as "button cells" or "coin cells."
The most common size of watch battery is the CR2032 battery. The CR2032 battery is a lithium coin cell battery that is 20 mm in diameter and 3.2 mm thick. Other common sizes of watch batteries include the CR2025, CR2016, and SR626SW batteries.
When choosing a watch battery, it is important to make sure that the battery is the correct size and chemistry for the watch. The watch's manual will typically specify the correct battery size and chemistry.
Here are some tips for choosing the right cell battery for your watch:
- Check the watch's manual to see what size and chemistry of battery is required.
- If you cannot find the watch's manual, look for the battery code on the back of the watch.
- Once you know the size and chemistry of the battery, you can purchase a replacement battery from a local store or online retailer.
- Be sure to dispose of old batteries properly.
I hope this article has helped you understand how cell battery sizes work and how they work with watches.
