What is a car battery? Overview of car batteries
What is a car battery? The car battery is a place to store the necessary electricity to provide the power to start the car. At the same time, it can also be seen as a place to store batteries that can be reused many times through charging. This device is extremely useful with the following uses:
Provide energy to operate the car, start the auxiliary equipment in the car such as air conditioner, lights, radio, ...
When the devices in the car use the electricity generated by the generator, the battery will continue to charge and convert into stored energy for later starting.
Construction of the battery
Usually the battery has a white or black rectangular box, with a tight lid on it. The battery has 2 convex poles above which are the positive and negative poles of the battery. Each pole will have a different color, usually blue for the anode and red for the cathode.
Batteries are of two types:
Water battery
Dry battery
The internal structure of the car battery includes: baffle, cathode plate, anode plate containing H2SO4 acid solution.

Voltage of the battery
The voltage listed on each battery is usually 6V, 12V, 24V . But the actual voltage of the battery supply is larger. If the vehicle's electrical system is only suitable for batteries with a voltage of 12V, but using a battery with a voltage of 24V, it will damage the vehicle's electrical system. Therefore, it is necessary to choose a battery with the appropriate voltage.
Capacity of the battery
Capacity is the basic parameter of the battery, this parameter indicates the capacity of the battery to store electricity. The usual unit of this parameter is Ah (Ampere hour).
For example, a battery marked 60Ah will be able to generate a current of 6A for 10 hours continuously, or 10A for 6 hours continuously. If the discharge current is larger, the remaining battery capacity will be smaller and vice versa.
Some brands of car battery production today:
Amaron battery
Rocket brand battery
Battery manufacturer Atlas
Battery brand Varta
Signs of a damaged car battery
How to check a damaged battery is quite easy through the basic signs. Users can apply one of the following 4 ways to check:
The battery warning light on the taplo meter is on
The warning light on the taplo meter glows as a way to check the battery is damaged. At this time, people will need to bring the car in for inspection and may need to replace the device.

Starting takes longer than usual or the engine starts weak
You can apply the way to check the battery for possible failure through the car's starting process. If it takes too long or the engine runs weak, people should replace it. In addition, in the case of starting the engine for more than 30 minutes and then turning it off and on again without success, it means that the car's battery is damaged.
Cars are difficult to start in the morning
When the car is left overnight, the engine does not need to run and the battery will not be charged. Therefore, a cool start the next morning will require a greater amount of friction and amps. This also causes the battery's ability to supply electricity to become weaker. Therefore, when you find the car difficult to start in the morning often, you should check it immediately!

10 Signs the battery needs to be checked
Very simple manipulation. People can apply one of the following methods:
Use a voltmeter to measure the voltage of the battery
The simplest way to check the battery is to use a voltmeter to measure the voltage of the device. This very familiar tool helps you to capture the potential difference between the positive and negative terminals of the plate.
How to measure battery with voltmeter by following steps:
Step 1: Turn off the engine to make sure the power is completely cut off.
Step 2: Remove the positive battery cover and clean the two poles
Step 3: Connect the corresponding terminals of the tank and voltmeter carefully
Step 4: After the polarity is completed, you proceed to check the parameters on the voltmeter
Step 5: Review the displayed voltmeter results to make the most accurate conclusions
– If the voltmeter displays a reading between 12.4 and 12.7V, the battery is still in good working order.
– If the voltmeter shows results below the threshold of 12.4V, it means that the battery is in need of charging.
– If the voltmeter shows a reading lower than 9.6V, it indicates that the battery is weak, damaged and needs to be replaced.
Battery voltage indicator and condition when charging:
12.68v . . . . . . . . . . 100%
12.45v . . . . . . . . . . 75%
12.24v . . . . . . . . . . 50%

There are many ways for you to test your battery
Use a voltmeter to check a car battery
Use a circuit meter to check the contact at the car battery battery
The second way to test the battery is to use a circuit meter to conduct a contact test. For lead acid equipment, people need to maintain a constant power supply. This helps to keep the lead electrode plates inside from being damaged or damaged. Besides, if sulphation occurs, the battery will not be able to be fully charged. Therefore, it will prolong the life of the device.

Check equipment with activated carbon cylinders
The way to test batteries with activated carbon cylinders requires people to fully charge the electricity to ensure the most accurate results. You conduct a water level analysis of the hydrolysis solution inside the instrument. If it is full, the battery needs to be recharged and then tested again.
Check with an electronic watch
In addition to analyzing the hydrolysis solution, the battery test can also be carried out more quickly through the electronic meter. Everyone needs to fully charge the battery to ensure the most accurate display results before proceeding to use the measuring device. Electronic meter specialized for testing the level of conductivity and predicting the current condition of the battery.
This tool helps you to realize the electrode plate charge, how much is the actual volume and how is the power supply capacity? All these indicators are displayed in the most detail and clarity through the electronic clock.
Causes of battery failure and how to fix it
In addition to understanding how to check a damaged battery, it is also important to find out the causes and remedies. So what are the factors that affect the longevity of this product? Detail:
No regular maintenance – Running out of fluid: This is the leading cause of battery failure. The lack of maintenance and frequent use causes the shortage of electrical fluid. Therefore, you should care, check and clean the device regularly during use.
Improper maintenance – Reducing battery capacity: Even if you go for maintenance such as improper conduct or misuse, it will affect the life of the battery. This will make the device often damaged and difficult to recover. In addition, depending on the type of vehicle, you need to use the right type of battery as well as the right purpose.
Explosion of the tank: Usually, the explosion of the tank is caused by short-circuiting or poor contact with equipment and motors. Also can happen because the vent on the button is blocked because of the spark. If you encounter this situation, you can add more distilled water to overcome and repair. However, to ensure absolute safety, everyone should replace the battery with a new one.
Electrolyte depletion (Electrolyte level is lower than Low Leave)
Cause: No regular maintenance, in the process of using the battery.
Prevention: should take care. Check and clean the battery and equipment on a regular basis during use.
How to handle: Add distilled water (support maintenance) ((absolutely not add mineral water, or strange solutions.
The phenomenon of sulfation
Main cause: The battery is exhausted but not recharged. Incorrect charging mode, insufficient capacity, or multiple under-capacity recharges lead to more and more sulfate accumulation. The vehicle's charging unit (vehicle) is not functioning properly. The vehicle's wiring system (vehicle) is short-circuited causing self-discharge of the battery.
Fix: Need to recharge periodically (at most every three months) according to the required charging mode.
The phenomenon of reverse polarity
The phenomenon of reverse polarity of the battery is due to the battery being connected to the opposite polarity during use or when charging.
Phenomenon: The color of the two types of polar leaves is quite similar.
