In electronics, a battery or voltaic cell is a combination of one or more electrochemical Galvanic cells which store chemical energy that can be converted into electric potential energy, creating electricity. Since the invention of the first Voltaic pile in 1800 by Alessandro Volta, the battery has become a common power source for many household and industrial applications, and is now a multi-billion dollar industry.

Any type of batteries that has a lithium anode that is used in many portable electronic devices.

A device used in recharging the battery by forcing an electric current through it.

Digital cameras have high power requirements, and over time have become smaller, resulting in an ongoing need to develop a battery small enough to fit in the camera and yet able to power it for a reasonable length of time. Two broad types of batteries are in use for digital cameras.

A battery is a device that converts chemical energy directly to electrical energy.

The charge current depends upon the technology and capacity of the battery being charged. For example, the current that should be applied to recharge a 12 V car battery will be very different from the current for a mobile phone battery.

The alkaline battery gets its name because it has an alkaline electrolyte of potassium hydroxide, as opposed to the acidic electrolyte of the zinc-carbon batteries which are offered in the same nominal voltages and physical size.

phone chargers are not really chargers, only adapters that provide a power source for the charging circuitry which is almost always contained within the mobile phone.

Rechargeable batteries use electrochemical reactions that are electrically reversible.

Some cordless phones advertised as 5.8 GHz actually transmit from ... utilize two rechargeable AA or AAA batteries
