To power a wristwatch, you need a different kind of battery. Because of space constraints, watch batteries are usually much smaller than other kinds, and they also are designed to not leak on the inside of the watch. Some kinds of batteries are also made for certain types of watches, depending on the watch specifications. There are several types of watch batteries, each with their own pros and cons. Before shopping for watch batteries, it's helpful to know about the types available and the things you should be looking for in a watch battery.
Silver oxide batteries are some of the most common watch batteries that you will find. These batteries retain constant voltage and are good for watches that require this kind of power. Lithium batteries can be found inside watches, as well. These are usually made of lithium-manganese dioxide and look like small coins. Alkaline watch batteries are usually a mix of alkaline and zinc. These batteries are often found in low-quality watches and toy watches.
Figure out what kind of battery your watch needs before purchasing one. For instance, lithium watch batteries provide intermittent voltage and are best for watches that do not need constant power. Alkaline watch batteries do not have a long shelf life and should not be used to replace batteries in high-end watches.
You should familiarize yourself with the battery requirements of your watch, in addition to getting the right size, which should be printed either on the watch itself, on the packaging or in the manual. To find high-end watch batteries, it's a good idea to visit the manufacturer or dealer. Often, these kinds of watches will have special parts that can only be found this way. Check the manufacturer's website to find dealer locations. If your watch is less expensive, you can find most kinds of watch batteries by visiting jewelry stores, department stores and even some drug stores.
