Nickel metal-hydride batteries. A nickel-metal hydride battery, also known as NiMH, is a secondary cell, meaning it is a rechargeable battery.They are used in cameras and other electronic devices. They are made in several sizes; AA is the most common. They are similar to nickel-cadmium batteries but store twice as much energy.
