 Rechargeable battery - Wikipedia, the free encyclopedia
Rechargeable batteries are batteries that can be restored to full charge by the application of electrical energy.
Some types of rechargeable batteries are susceptible to damage due to reverse charging if they are fully discharged; other types need to be fully discharged occasionally in order to maintain the capacity for deep discharge.
Old and new batteries and batteries of varying types or brands should not be mixed in the same circuit.

 Battery - MSN Encarta
Batteries in which the chemicals cannot be reconstituted into their original form once the energy has been converted (that is, batteries that have been discharged) are called primary cells or voltaic cells.
Batteries in which the chemicals can be reconstituted by passing an electric current through them in the direction opposite that of normal cell operation are called secondary cells, rechargeable cells, storage cells, or accumulators.
The Edison battery has a useful life of approximately ten years and produces about 1.15 V. Another alkaline cell similar to the Edison battery is the nickel-cadmium cell, or cadmium battery, in which the iron electrode is replaced by one consisting of cadmium.

The disadvantages of lead-acid batteries are the weight, the short useful life (2-5 years), the lead ingredient that is poisonous and the fact that it creates a potentially explosive mixture of hydrogen gas.
During this step, the battery terminals are connected to a source of electricity and the battery is charged for many hours.
When a spent battery is collected, it is sent to a permitted recycler where, under strict environmental regulations, the lead and plastic are reclaimed and sent to a new battery manufacturer.

 What is Electricity?
Electricity is a basic part of nature and it is one of our most widely used forms of energy.
Electricity is a controllable and convenient form of energy used in the applications of heat, light and power.
Hydropower, the source for almost 7% of U.S. electricity generation in 2005, is a process in which flowing water is used to spin a turbine connected to a generator.

 PowerPedia:Electric Battery - PESWiki
However, the batteries which they reproduced did not produce a substantial amount of energy and had to be connected in series in order to test the myths.
It had been long known that continuous electric currents flowed through the solid and liquid portions of the Earth and the collection of current from an electrically conductive medium in the absence of electrochemical changes (and in the absence of a thermoelectric junction) was established by Lord Kelvin.
In this sense fuel cells, as sources of electricity, and flow batteries, for storage of electricity, may be seen as complementary in achieving a hydrogen economy.

 Basic Chemical Production of Electricity
Electricity generated directly by heat, pressure and friction tend to be either very small--the microvolt output of a thermistor when exposed to heat, or the equally small output of a crystal microphone when subjected to sound pressure--or uncontrollable, as in the case of lightening, caused by friction.
In a battery, there is always a flow of electrons in the external circuit (the electrical circuit or device) and a corresponding flow in the internal circuit (the electrolytic circuit).
Since the electromotive force of a battery is dependent not only upon the nature it's components, but also upon the concentration of it's electrolytes, the gradient of concentrations that results from the production of electricity causes the battery to generate lower and lower voltages and currents until finally it is considered dead.

 Basic Electricity
In Volta's honor, we refer to electrical pressure as "Voltage" and we measure the amount of electrical pressure in units of "Volts".
When the battery is on the shelf, or in a circuit that is turned off, the electrical pressure builds up to the point where the chemical reaction essentially stops.
When the battery is in a circuit and current is flowing, the chemical reaction is going on, moving new electrons into position as the previous electrons flow out through the circuit.

And again similar to a battery, electricity is later drawn from the combination of fuel cell and hydrogen.
The original electricity in both cases is generated from fossil fuels, nuclear power or hydroelectric dams, with a few percent coming from solar photovoltaics and wind turbines.
The main distinction is that the battery that is charged and the electricity released later come from the same physical unit while in the case of the fuel cell/hydrogen combination, the hydrogen tank is ìchargedî and the fuel cell can be at a different locale.
