Alkaline v Lithium Watch Batteries
Tuesday, June 1, 2010
When you are replacing your watch battery, there are two main choices: lithium and alkaline. Some people may believe this decision is superfluous, but your verdict will have an impact on both the performance and longevity.
An alkaline watch battery is comprised of zinc and manganese dioxide, which combine to form a chemical reaction. These batteries are considered a middle-of-the-road option, as they are relatively inexpensive, have a high energy density and a long shelf life. If you want a top-of-the-line battery however, go with lithium. Lithium watch batteries have the capacity to produce higher voltages and have a long life span, making them ideal for frequently used devices, such as watches.
