Standby power. Standby power, also called vampire power[1], vampire draw, phantom load, ghost load, or leaking electricity, refers to how electronic and electrical appliances consume electric power. At the same time, they are switched off (but are designed to draw some power) or in standby mode. It only occurs because some devices claim to be ...
Reserve battery. A reserve battery, also called stand-by battery, is a primary battery where part is isolated until the battery needs to be used.

The maximum electromotive force offered by a Ni–Cd cell is 1.3 V. Ni–Cd batteries are made in a wide range of sizes and capacities, from portable sealed types interchangeable with carbon–zinc dry cells, to large ventilated cells used for standby power and motive power. Compared with other types of rechargeable cells they offer good cycle ...
An uninterruptible power supply (UPS) or uninterruptible power source is a type of continual power system that provides automated backup electric power to a load when the input power source or mains power fails.
