Everyone knows that any modern vehicle has at least one battery. You buy it, put it under the hood and go on your way. However, no one knows how it works and what happens if you put a different amperage than the one indicated by the manufacturer.

What is the car battery?
The car's battery is a fast-charge battery that provides power for startup, ignition, and lighting. In fact, the primary purpose is to start the vehicle's engine because, after starting, electricity is provided by the belt drive alternator. It should be noted that in the case of a new battery, an engine start-up consumes less than 3% of the capacity. So if the engine does not start, you can turn on the car about 30 times.

Car batteries are the lead-acid type, meaning they have inside cells of lead and sulfuric acid that give a voltage of 12 volts. This voltage is generally provided by six cells of 2 volts each, connected in series.

Types of auto accumulators
BATTERY MAN GUIDE provides us with information on this topic. There are four types of batteries for our cars: with maintenance, with no support, gel-sealed, for Start / Stop.

Fortunately, maintenance batteries are starting to disappear from the market. These are batteries that, after the electrolysis process inside, evaporate the liquid and need to be filled in time. Modern cells, as they are now mostly known, are maintenance-free and manage to keep the fluid throughout its working life. The most efficient type of accumulators is that sealed with gel, that is, those who use an electrolysis gel, particular thought for massive power consumption. They are used in various applications or cars with large engines and additional consumers, as well as in car-audio competitions. The latest battery type is the newest, unique for Start / Stop machines. They are maintenance-free batteries with high-speed charging, allowing for better storage of the electricity.

What is happening inside a car battery?
An accumulator is usually made of 6 galvanic cells connected in series. Each produces 2.1 volts and offers, at maximum load, 12.6 volts. Each cell is made up of several lead plates, some of the cathodes, some of the lead lead-bearing lead being an anode. The two types of plates are alternately arranged and flooded in an electrolytic or sulfuric acid solution. With the help of the liquid, the two plates produce a chemical reaction that releases electrons that pass through the conductors, making electricity. Just like in a watch, telephone, or flashlight.

As the battery gets discharged, the acid in the electrolysis solution turns the surface of the lead plates into lead sulfate. When it is charged, the chemical reaction is reversed, and the lead sulfate turns back into lead dioxide until the plates are at the beginning. After that, when it pulls out again, the battery is discharged, and the whole process is repeated.

What does “my battery is dying” mean?
It often happens that our battery dies, meaning the electric motor not working, sign that a new one is needed. What is happening in this situation? You must remember that the battery that lasts a whole life has not been invented yet. Because there is still no material to resist infinitely following these loading/unloading cycles.

When a battery is dead, usually after 3-6 years of use, the surface on which the lead-oxide lead sheets have been removed has disappeared. This means that lead sulfate can no longer be converted to dioxide loading and the electricity can no longer be stored. Alternatively, the electrolysis substance, which is a chemical, has also lost its properties and is now only cold water that no longer produces any chemical reaction. The fact is that the accumulator can no longer be used and requires replacement. Read more here.

When can we put it on the rectifier?
Many drivers have the impression that if they put a dead battery on the rectifier, they will bring it back to life. However, the rectifier is not a means of renewing it, but only to recharge it. That is, the purpose of the rectifier is to bring good batteries to life, with all the components still active but wholly discharged from an accidental cause.
