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: The car battery is the source of energy for the car to operate The car battery is the source of energy for the car to operate 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. Components of the battery pack:
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:

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%
12.06v . . . . . . . . . . 25%

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.
