Uniross batteries are perfect for replacing ordinary batteries in almost any appliance; they will also last longer than Alkaline batteries when used in high drain, frequent use devices such as Digital Cameras, and, unlike Nickel Cadmium batteries, they do not suffer from any memory effect. A Nickel Metal Hydride battery can be recharged & re-used up to 1000 times which also helps to protect our environment from empty Alkaline batteries.
