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. The genius in these 5 inventions is that they stayed basically unchanged for all of these years giving the driver comfort, safety and reliability
Of course, in modern cars, there are battery charge indicators (in the same panel as the speedometer, fuel gauge and temperature gauge). Using these indicators, you can be able to know when your battery is developing problems, like when it is losing charge too quick, even without opening your car's bonnet. Naturally, these indicators only work for as long as the battery is at least 'basically functioning;' for it is the very same battery that powers them.
