What Causes Corrosion on Automobile Batteries?
Basics All parts of the electrical system in an automobile rely on the battery to provide the power to run the systems. Because batteries are made of lead and contain acid, the combination can be very corrosive if not maintained properly. A car battery is an electrochemical piece of equipment that converts chemicals into energy and sends the current through the wires attached to the battery leads. Most standard batteries provide twelve volts of power, which are fired by six cells, each of which produces two volts. In addition to the acid in each cell, there are negative and positive plates made of lead that balance the charge and carry the current through the battery. The battery case that holds all the pieces together is made from heavy-duty plastics. A maintenance-free battery is made of heavy-duty parts throughout the battery and is housed in a closed case. Corrosion Corrosion can be caused by a number of different factors. Older batteries that required water to be added were open t
