Watch battery with special trait-
A significant characteristic that differentiates watch battery from all other cells is that it is designed to have an extremely precise tolerance in order to reduce the risk of leakage. Watch batteries or a battery of any other product may differ, according to manufacturer. For instance, Energizer L91 AA Batteries may not be same as that of Duracell batteries of same standard.
Each cell type has unique features, and so, you have to buy one depending on the application of the battery. For some of the applications, there is a need of extreme amount of current, just for shorter period, while others involve limited time with lower current. Any single cell type is not able to fulfill all the requirements. The main consideration for the design of battery is an effect on environment. So, mercury batteries are not produced nowadays. But, in the past fifty years, mercury based batteries had been used by the consumers. They work with 1.36 V, and because of increasing environmental issues, manufacturing process has been stopped.
Voltage for watch battery-
You have perhaps used Energizer L91 AA Batteries for many purposes. However, for watches, 3.0 V batteries are often chosen. Their voltage is quite stable, and there is no presence of risky chemical substance. If you have quartz timepiece, you may purchase these batteries. Moreover, lithium batteries can also work for more than five years.
