How does an automobile battery work?

How does an automobile battery work to produce electricity, and how is the battery kept charged?



I need a very detailed response. My students need to write a 1/2 page on this and I want to see where most people find their information for this question.



Thank YouHow does an automobile battery work?The auto battery is usually a 12 volt electrical energy storage device. It has two poles, one + and one -. On the inside there are 30 - 50 dissimilar lead plates immersed in an electrolyte solution of 20% Sulphuric Acid and distilled water. There are usually six cells in an auto battery, each cell developing about 2.2 Volts DC. The cells are tied together with links in a series. A fully charged battery should measure about 13.2 Volts from the + to - terminals.

The battery is charged by an alternator which generates a voltage of about 14.2 VDC which is enough to drive a DC current of from 2 - 20 amperes into the battery for storage. Electrical devices in the car can draw current from the battery to power the many devices that provide you with pleasure and mobility so you can get to school on time.
