Button/Coin Cell Batteries
Alkaline, Silver Oxide, Zinc Air
Sized to fit into devices with small battery compartments, these batteries are often used with watches, sensors, and calculators. When choosing a battery, use the capacity, measured in milliampere-hours, to compare among similar sizes. The higher the mA-hr. rating, the longer the battery should last.
Silver oxide batteries last longer than alkaline batteries.
