Battery

A hardware device that supplies power to a device or appliance and enables that device or appliance to work without a power cord. The standard battery will power a small device or appliance for a length of time dependent on how much the device or appliance is used and how much power is required. Once fully utilized, the standard battery is disposed of. Today, many high-end devices such as computer laptops and cell phones use rechargeable batteries that allow a user to recharge the battery once it has been depleted of power.
