Jump-Start Your Battery Safety

(12 min.) A car battery is a rechargeable cell in the starting-lighting-ignition variety of batteries. They are also in the lead acid family of batteries. Lead acid batteries are the oldest style of rechargeable batteries. The high power output of a car battery is necessary to supply a high current draw needed for the engine starter. A normal car battery provides about 12.6 volts and is divided into 6 separate cells and each cell produces about 2.1 volts per cell. As the battery state of charge decreases, the voltage produced also decreases.

Battery power is created through a chemical reaction. Inside your battery there are positive and negative lead plates that are immersed in an electrolyte solution called battery acid. This solution is a combination of water and sulfuric acid. When the solution interacts with the lead plates, the chemical interaction creates voltage. This voltage is then released through the battery''s positive terminal (red) and returned to the negative terminal (black). Voltage from the alternator maintains the battery state of charge. This continuous cycle can produce electricity for years.

Topics included in this safety video are: basic problems, using a regular charger, jump charging a dead battery, basic battery maintenance, and other battery information.

Program comes with a CD-ROM of written materials, including test questions and answers. English title also includes PowerPoint presentation.
