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.
Battery: this invention has made the complete car electric system possible. From the old heavy and unreliable ones to today's modern batteries, it's something that a car can't go without. In the invention of the batteries lay the seeds of today's modern electric-cars. Spark plug: today it's an usual item in car mechanics. But think of the people that invented it!! Lighting the fuel-air mix with an electric spark, simply amassing. How great it is, proves the fact that the principle is unchanged ever since. Every invention on the car has it's purpose and, in mechanical terms,it's own beauty. Ranking of this kind doesn't neglect all of the other marvels on the car, on the contrary.

3D wheel aligner - This auto diagnostic tool prevents accidents and allows more efficient use of tires and fuel. Most car repair shops have one of these because they help in saving a lot of any client's money. This auto electric repair tool consists of 3D cameras that track a vehicle's wheel movement and positioning from any height. Some functions like rolling compensation can be done without having to lift the car off the ground meaning that readings and subsequent adjustments are done in a very short time. A 3D wheel aligner has quite a number of components built into it, some of which include: Drive on camera aid, VIN scanner, Steering angle sensor, Universal wheel clamps etc.
