As portable electronic devices have become smaller, lighter, and more sophisticated, the batteries that power these devices have had to provide ever increasing levels of energy. Nickel metal hydride batteries provide such a solution with a nickel hydroxide positive electrode and a negative electrode comprised of hydrogen absorbing alloys.
The nominal voltage rating of the Nickel Metal Hydride cell is 1.2V, with energy usable in the range of 1.0V – 1.45V per cell. A variety of cylindrical cell sizes are available, providing a capacity range from a few hundred mAh to above 10Ah.
Nickel Metal Hydride battery packs can accept charge and discharge rates as high as 1C (typically equal to the rated capacity of the cell). As a result, products can perform challenging tasks and require minimal time to recharge, reducing downtime of the portable device.
