Watch Batteries
Types of Watch Batteries : There are three main types of battery that are used to power watches. The most common is the silver oxide battery. They are frequently used in watches because they have a high energy to weight ratio. This means that they should last for a long period of time. Due to the silver content they can be expensive to produce which is why they are not often used for products that take larger batteries.
Alkaline Watch Batteries : If you've purchased a cheap watch, chances are this is the type of battery it has in it. In fact, it's hard to find a cheaply made watch that doesn't have an alkaline battery in it.
