Whois & Analysis for energizer.com

Energizer Holdings is an American manufacturer of batteries, headquartered in Town and Country, Missouri.

It produces batteries under the Energizer and Eveready brand names, and formerly owned a number of personal care businesses until it separated that side of the business into a new company called Edgewell Personal Care in 2015.

An electric battery is a device consisting of one or more electrochemical cells with external connections provided to power electrical devices such as flashlights, smartphones, and electric cars.

When a battery is supplying electric power, its positive terminal is the cathode and its negative terminal is the anode.

The terminal marked negative is the source of electrons that when connected to an external circuit will flow and deliver energy to an external device.

When a battery is connected to an external circuit, electrolytes are able to move as ions within, allowing the chemical reactions to be completed at the separate terminals and so deliver energy to the external circuit.

It is the movement of those ions within the battery which allows current to flow out of the battery to perform work.

Historically the term "battery" specifically referred to a device composed of multiple cells, however the usage has evolved to additionally include devices composed of a single cell.

A flashlight (often called a torch outside North America) is a portable hand-held electric light.

The source of the light is usually an incandescent light bulb or light-emitting diode (LED).

A typical flashlight consists of a light bulb mounted in a reflector, a transparent cover (sometimes combined with a lens) to protect the light source and reflector, a battery, and a switch.

These are supported and protected by a case.

Lighting or illumination is the deliberate use of light to achieve a practical or aesthetic effect.

Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight.

Daylighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings.

This can save energy in place of using artificial lighting, which represents a major component of energy consumption in buildings.

Proper lighting can enhance task performance, improve the appearance of an area, or have positive psychological effects on occupants.

In physics, power is the rate of doing work.

It is the amount of energy consumed per unit time.

Having no direction, it is a scalar quantity.

In the SI system, the unit of power is the joule per second (J/s), known as the watt in honour of James Watt, the eighteenth-century developer of the steam engine.

Another common and traditional measure is horsepower (comparing to the power of a horse).

Being the rate of work, the equation for power can be written:
