How Does A Car Battery Work?

(Last Updated On: June 4, 2020)

Whenever you insert the car keys inside, the engine will start up, and a signal is sent to the battery of the car. As soon as the car’s battery receives the signal, it will convert the chemical energy into electrical energy. The electrical power is provided to the starter, which will crank the engine. The battery is also responsible for providing power to the car’s lights and other essential accessories. If you want to have a complete idea about how does a car battery works, take a detailed reading of this buying guide below:

Battery Voltage

Voltage is the amount of electrical power which a battery can hold. Nowadays, the standard battery which is suitable for all types of cars will have energy of 12 V. Each battery contains six cells in total, and once you charge it, it will deliver 2.1 Volts. You can consider that the battery is fully charged if it shows 12.6 Volts or higher. If the voltage of the battery falls, the performance will be affected by a considerable margin. You can choose to have a battery which is economical but keep a check on the highest level of voltage it can provide to your car.

Chemical Reaction

A battery is full of electrical energy, which can be generated by a chemical reaction. If the battery is constructed with acid and leads, it will react with the car’s engine differently. If you want the battery to make the startup process easy, it will require at least 12.6 Volts. The weight percentage of the acid and sulfate must be 25% or more, or else the battery won’t work well. The chemical reaction is completely reversible, and that is why you can continue to charge the battery for a long time. When the right amount of current is sent to the battery, and the voltage is also in a good position, it will help to start the engine quickly. You will notice that a layer of lead and lead oxide will form on the plates to give an excellent performance. You can reuse the battery anytime and any day as much as you want.

Cranking Power

Every vehicle needs the right amount of cranking power to start up instantly. The ability a car requires depends on the engine’s size, type of the engine, and even the temperature. If the temperature drops that will mean a high power will need to start the engine.CCA is the rating that will help to measure the cranking power of the battery. The lead-acid batteries are known to be wholly reliable, but they do have temperature changes. Sometimes their motion and cramped conditions may not be easy to handle, but it can easily last for about five years. If you want to check out the battery capacity, you can test it with a virtual battery tester and know precisely how much juice is left inside. Even if you go to your local auto mechanic shop, they can check and analyze the battery for you. If the battery is good, your car will run smoothly for a much longer time.
