Auto Electrical Basics

Automobile is powered by Elctrical and Electronic systems.

First and importend componant is a Battery.

You can learn littlebit about a Battery fitted on your car.

What is battery in the car?

A car battery is a type of rechargeable battery that is used to start a car and provide power to its electrical components. It is also known as a lead-acid battery, because it consists of lead plates and sulfuric acid. The battery is made up of cells, each of which contains a positive and a negative electrode (made of lead) and an electrolyte (sulfuric acid). When the battery is in use, the sulfuric acid in the electrolyte reacts with the lead electrodes to produce lead sulfate and electricity. When the battery is being charged, the reverse process occurs, and the lead sulfate is converted back into lead and sulfuric acid. A car battery is an essential component of a car's electrical system, as it provides the necessary power to start the engine and run the electrical components (such as the headlights, radio, and windshield wipers). It is also used to store electricity generated by the alternator (which charges the battery while the car is running) for use when the car is not running.

How to take care of car battery - fault finding, removing and fitting, testing and diagnosing problems?

1. Keep the battery clean by removing any corrosion from the terminals. You can do this by using a mixture of baking soda and water to create a paste, applying it to the terminals, and then rinsing it off with water.

2. Make sure the battery is securely fastened to the car. Vibrations can cause the battery to loosen, which can lead to problems.

3. Keep the battery charged. If the battery is not being used (such as during the winter months), it is a good idea to charge it every few months to keep it in good condition.

4. If the battery is not being used for an extended period of time (such as during long-term storage), it is a good idea to remove it from the car and store it in a cool, dry place.

To remove and fit a car battery, you will need to:

1. Locate the battery. It is usually located in the engine compartment, either on the side or on the top of the engine.

2. Disconnect the negative terminal (usually marked with a "-" sign) from the battery. This is important to prevent any accidental short circuits.

3. Disconnect the positive terminal (usually marked with a "+" sign) from the battery.

4. Remove the hold-down clamp that secures the battery in place.

5. Lift the battery out of the car.

To install a new battery, simply reverse these steps. Make sure to connect the positive terminal first, and then the negative terminal.

To test a car battery, you can use a voltmeter or a hydrometer. A voltmeter is a device that measures the voltage of the battery. To use a voltmeter, set it to the appropriate range and touch the probes to the terminals of the battery. A fully charged battery should have a voltage of around 12.6 volts.

A hydrometer is a device that measures the specific gravity of the battery's electrolyte. To use a hydrometer, remove the caps from the cells of the battery and draw a sample of the electrolyte into the hydrometer. The specific gravity of the electrolyte will indicate the state of charge of the battery.

If you are experiencing problems with your car battery, it could be due to a number of issues. Some common problems include a dead battery (caused by a lack of charge), a weak battery (caused by sulfation or corrosion on the terminals), or a faulty alternator (which is responsible for charging the battery). To diagnose the problem, you may need to perform some tests or take the car to a mechanic.

Is it needs to afraid about car battery handling, what are the precuations to take when removing and fitting a battery?

It is generally safe to handle a car battery as long as you take proper precautions. Here are some things to keep in mind when removing and fitting a car battery:

1. Wear protective gear. It is a good idea to wear gloves and safety glasses to protect your hands and eyes from any acid that may leak from the battery.

2. Disconnect the negative terminal first. This is important to prevent any accidental short circuits.

3. Be careful not to drop the battery. A dropped battery can be damaged, which can cause it to leak or fail.

4. Make sure the battery is securely fastened to the car. If the battery is not properly secured, it can move around and cause problems.

5. Keep the battery away from open flames. Batteries can release hydrogen gas, which is flammable.

6. Dispose of the battery properly. If you need to dispose of an old battery, take it to a recycling center or a place that specializes in battery disposal. Do not throw it in the trash.

Overall, as long as you follow these precautions, you should be able to safely handle a car battery. If you are not comfortable working with a car battery, you can always ask a mechanic to do it for you.
