I was shocked when I would turn on the vehicle in the morning. The car cannot be ignited, even though it has been redesigned many times. I opened the hood of the car engine and tried to check. I suspect the damage is in the car battery sector. Then I took the battery to the repair shop for repair.

The car battery is actually 6 small batteries arranged in series. This gives a total voltage. Batteries use lead-acid battery technology. This technology is relatively cheap and reliable. The battery must withstand harsh environments, such as high temperatures and lots of vibration. Car batteries will usually last three or four years.

As long as it works, the car battery is something great. With high-quality batteries, reliability can last for years. This, of course, depends on the maintenance of the vehicle battery. Care is taken to ensure maximum efficiency in the electrical system and battery charging.

Car Battery: The Basic Structure

The first thing to understand is that the car’s battery is not the same as a battery that is usually used for electronic devices. Car battery, this is usually 12 volts. Various other vehicles use the same battery technology in various voltages, but the principle remains the same.

In general, the battery works when the electronic circuit is connected to the battery. electrons flow, with negative elementary electrical charges. Electrons play all important roles in providing power.

The battery is composed of 3 main things. There are 2 connectors coming out of the battery, which is known as cathodes and anodes. The third is the solution. During normal operation, a chemical reaction occurs between the solution and the anode that releases electrons flowing through the circuit. This reinserts the battery through the cathode where other chemical reactions occur between the cathode and the solution. Electrons are included in this reaction product. When running in reverse (with a certain battery), electrons are forced in the other direction in the back reaction. When the battery dies, usually because one or more of the chemical reactants are more or less used.

In car batteries known as lead-acid batteries, the cathode is lead dioxide (PbO2), the anode is a lead sponge (Pb), and the solution is sulfuric acid (H2SO4). When the battery is being used, connection 2 reacts to form lead sulfate (PbSO4) by reacting with sulfuric acid.



The opposite reaction occurs when the battery is being recharged. This reaction produces around 2V. So in total 6 battery cells produce 12V voltage. This voltage is needed to turn on the car. This inverse reaction allows the battery to be used repeatedly. The reaction is not permanent, with lead sulfate turning into lead dioxide. Over time, battery efficiency will run out. The battery can work optimally for about four years.


It turned out that my car’s battery was damaged. Evidently, after being stunned and the battery installed, the car can be turned on. Indeed, the battery life is more than 2 years, it’s time to buy a new battery. I prefer to use a wet battery, which is a battery by charging a solution. This type of battery needs maintenance and routine inspection of the solution. Actually very simple, because the treatment is only 2 months. Of course by adding distilled water to the battery. Easy isn’t it?
