What is a Battery?
Battery is an
electrochemical device that converts chemical energy into
A galvanic cell is a fairly simple device consisting of two
electrodes (an anode and a cathode) and an electrolyte solution.
Batteries consist of one or more galvanic cells.
The American National Standards Institute (ANSI) Standard, ANSI
C18.1M-1992, lists several battery features that must be listed on a
battery's label. They are,
• Manufacturer -- The name of the battery manufacturer.
• ANSI Number -- The ANSI/NEDA number of the battery.
• Date -- The month and year that the battery was manufactured or
the month and year that the
battery "expires" (i.e., is no longer guaranteed by the
• Voltage -- The nominal battery voltage.
• Polarity -- The positive and negative terminals. The terminals
must be clearly marked.
Warnings -- Other warnings and cautions related to battery usage and
One Of The Types : Lead-Acid Battery
Lead-acid batteries, developed in the late 1800s, were the first
commercially practical batteries. Batteries of this type remain
popular because they are relatively economical to manufacture. The
most widely known uses of lead-acid batteries are as automobile
batteries. Rechargeable lead-acid batteries have been available
since the 1950s and have become the most widely used type of battery
in the world—more than 20 times the use rate of its nearest rivals.
In fact, battery manufacturing is the single largest use for lead in
PbO2 + Pb + 2H2SO4 —> 2PbSO4 + 2H2O
Lead-acid batteries remain popular because they can produce high or
low currents over a wide range of temperatures, they have good shelf
life and life cycles, and they are relatively inexpensive to
manufacture and purchase. Lead-acid batteries are usually
Lead-acid batteries come in all manner of shapes and sizes, from
household batteries to large batteries for use in submarines. The
most noticeable shortcomings of lead-acid batteries are their
relatively heavy weight and their falling voltage during discharge.
