What is Battery ?

Otherwise known as “rechargeable batteries

Nominal Voltage....

Nominal Voltage....

The nominal voltage of a battery is the voltage stated by the manufacturer

A battery is an electrochemical cell (or enclosed and protected material) that can be charged electrically to provide a static potential for power or released electrical charge when needed.

A battery generally consists of an anode, a cathode, and an electrolyte.

For example, alkaline AA batteries are listed as having...

Common types of commercial batteries and some of their characteristics and advantages are summarized in the following table

slowly lose voltage

Relatively inexpensive; widely available

No memory effect; unused capacity remains usable

nominal voltage refers to the maximum or starting voltage of the battery...

Twice the charge capacity of Ni-Cd; slow self-discharge

A battery is a device that produces electrons through electrochemical reactions, and contains positive (+) and negative (-) terminals.

nominal voltage refers to the average voltage of the battery over its discharge cycle...

A battery consists of one or more electrochemical cells

which transform stored chemical energy directly into electrical energy.

When an external load connects to a battery, electrons cross from the negative to the positive terminal, creating an electrical current

A battery’s capacity is a measure of the amount of electric charge it

This current may power a motor, a light bulb, a clock, a computer, a cellphone, and other electronic devices or equipment. Battery flow speed is determined by the battery’s internal resistance and outside load.

Batteries are available in numerous sizes, which range from the miniature cells used in wrist watches and power hearing devices to batteries the size of rooms that are used to offer standby power for data centers and telephone exchanges.

The electrolyte is the substance....

The electrolyte also inhibits the flow of electrons
