Watch Batteries
To avoid damage caused by battery leakage, it is important to replace the battery as soon as possible after the watch stops.
If you don't have a self-winding or perpetual watch, the chances are that you will have to replace your watch battery every few years, depending on the age of the watch. Batteries come in a wide variety of sizes and are available at most watch repair and electronic stores. Although there are many different manufacturers, some model numbers can be used in a variety of watches.Types of Watch Battery
There are many different types of watch battery on the market. Each type has special characteristics making it suitable for certain applications. Some require a high current for a short period; others require a low current for a longer time. A single battery cannot provide all these characteristics, so the correct battery must be used in your watch for optimal performance.With the decline of mercury batteries, Silver Oxide succeeded them as a viable alternative. However, these batteries last about half as long as the mercury batteries. Silver Oxide is a suitable power source for any electronic device requiring an ultra-compact, long lasting, low voltage power source. These batteries provide long-term power for applications requiring continuous low power consumption.
For a longer lasting battery, a Lithium battery can be obtained. These batteries are commonly referred to as "coin cells" due to their thin, round shape. Alkaline cells are used in cheaper watches where cost is more important than battery longevity. They have about half the capacity of a Silver Oxide battery and a relatively short shelf life.
Replacement of Watch Batteries
To avoid damage caused by battery leakage, it is important to replace the battery as soon as possible. It is recommended that the watch be brought to an authorized dealer to replace the watch. Most dealers use a special case opening tool to remove the back cover, if you have ever tried to do this; you know it's not easy. Some watch warranties specify special procedures and replacement parts, so if your watch is of high value it would be wise to read the warranty booklet.Watch Battery Disposal
Alkaline, Lithium and Lithium Ion batteries shouldn't be disposed of in normal household waste. The other good reason to have your watch battery replaced by a dealer or specialty store is that these professionals collect used batteries and recycle them through licensed waste management companies.
