An auto battery is built up of six cells, each containing stacked positive and negative lead plates. These are divided and separated by insulators and immersed in an electrolyte, a liquid blend of sulfuric acid and water. However, some batteries, use a gel instead of the electrolyte. This is considered to be safer and because you do not have to refill it with electrolyte, it has been labelled "maintenance-free". Each cell generates or more correctly put, stores 2.1 volts for a total of 12.6 volts.
Aside from a dead battery or faulty charging system, the most common electrical issues owners are likely to experience are burned-out light bulbs. After bulbs, though, it's likely potluck: Electrical problems could crop up in many places, from the stereo to an electric motor for a power window or sunroof to an electric fuel pump packing it in. In addition, the cause might be bad wiring, a short, there may be a faulty switch or some other gremlin that's hard to pinpoint.
