The battery cell of the laptop is a lithium-ion battery 18650 with a capacity of 2200mAh, the voltage of a single battery is, the series connection of the battery increases the voltage, and the parallel connection increases the capacity, knowing this rule, you can calculate the number of batteries in the laptop battery by yourself.

If it is a lithium battery, it is necessary to divide or, which can be divisible is, for example, it is three cells strung together, that is to say, at least three sections, and then look at the capacity, if it is 4400, it means that it is two cells in parallel, each section has a capacity of 2200, there are six cells in it, if it is 6600, it is 9 sections, and it is also 2200 capacity per section, if it is 4000, it is also six sections, indicating that the cell capacity inside is a little lower, and it is 2000 capacity per section.

Generally, the battery has such a Peugeot, capacity: 3600, 3800, 4000, 4400, 4600, 4800, 5200, these are six sections, the larger the capacity, the greater the capacity of each cell, but the number of cells remains the same, and then there is:, capacity:

6000, 6400, 6600, these are nine sections, some stools are, the capacity is 4000, 4400, these are eight sections, and by pushing down, it is the number of cells of your battery.

Laptop batteries are generally composed of multiple small batteries, each small battery is larger than the thumb, round, 7,8 cm high, the voltage is empty and fully charged, the nominal number of the battery is V, for example, and then divided by 4 to get it, it proves that 4 batteries are connected in series.

And then look at the capacity of the whole battery, for example, 3800mha, it proves that there are two sets of series battery packs mentioned above, because those small batteries have a capacity of 1500 2000mha, or even more, and two groups are required to reach 3800mha.

According to this judgment, then this battery is 4 2 8 cells.

There is also a simple way: unplug the battery to see the number of contacts, and a few are a few cores.

The general appearance is not easy to see, because it is not professional. Teach you to look at the capacity, 4400mah 6 cores 6600 9 cores 880012 cores 4400 8 cores 6600 12 cores 2200 4 cores It's easy to see.

Remove the battery and have a mark on it

Isn't there a label on the battery.

Laptop battery can be said to be a very important existence in laptops, with the relationship of laptop batteries, people can use computers anytime and anywhere, regardless of the power supply. The battery capacity of the laptop will directly determine the time to surf the Internet, and when buying a laptop, consumers will also pay great attention to the battery capacity of the laptop. So, how long is a laptop battery capacity?

Those who want to know can take a look at the introduction of the relevant knowledge brought.

To understand the capacity of the laptop battery, the general laptop battery will be pasted with the capacity and other related information, such as the mainstream original battery capacity is mostly 3000-4000mAh, which can support 2-3 hours of Internet access; Some laptop batteries can have a capacity of up to 5000mAh; If it is not the original battery, it can reach up to 8800mAh and can be used for 4-5 hours. However, there is a very bad thing about the laptop battery, that is, the more times it is used, the capacity of the battery will be reduced accordingly, which shortens the use time, and makes the laptop battery bridge lose its advantages.

Laptop batteries are one of the features that make laptops stronger than desktops, because of the laptop battery, laptops don't need to be charged as often as desktops. Nowadays, most laptop batteries are nickel-metal hydride batteries, which are safe to use and have a large storage power. If you want to buy a laptop battery, you must know how to buy, and the common purchase methods mainly include:

1. Pay attention to capacity. It is best to know that the battery capacity of most notebooks is as introduced above, and it is best to choose a laptop battery with a standard capacity, so that the use time can be guaranteed to a certain extent, and it will not be too short.

2. Quality is very important. If the quality of the laptop battery is not good, then the components on the laptop may be burned out in the process of use, which is based on the damage to the use of the computer and brings certain troubles to daily life.

3. After-sales maintenance is very important. The shelf life of laptop batteries is very short, and it is important to know what kind of warranty conditions they can improve before buying to ensure that the laptop battery can be properly warranted if it breaks down in a short period of time.

The knowledge of laptop battery capacity and how to buy batteries will be introduced to you here, and I hope the introduction of the article can bring you good help. Laptop battery capacity is mostly fixed, but if you can master some energy-saving skills when using it, then even if the laptop battery capacity is limited, people can make the laptop battery last longer and use it better.

3800 mAh is 6 cores, 7200 mAh is 9 cores, and the general notebook on the market is 6 cores. The 4600 is also 6 cores.

Laptop batteries are usually constructed using standard lithium batteries connected in series and parallel. The voltage of a single cell of a lithium battery is about 2500mAh.

If the battery of the notebook is 4800mAh, it is composed of three strings (3 taels (2*2500 4800mAh), which is a 6-cell battery, which is also a common battery standard for notebooks.

If the laptop battery is yes (some ASUS notebooks), it's an 8-cell one.

So knowing the voltage and capacity of a laptop battery, you can deduce how many cores there are.

Current notebooks have 4 cores and 6 cores, and if you want to know how many batteries you have, provide a method as follows:

Currently notebook cells.

Mainly 18650 model cylindrical lithium cells, the capacity is 2400mah, the nominal voltage is, understand these points, then look at the voltage of the notebook battery, than the world is sleepy, indicating that the battery has a series, and then look at the capacity, for example, the capacity is 7200mah, indicating that there is a parallel connection.

The number of cells can be calculated in this answer: (7200 2400)* (So this battery is 6 cells, and other batteries can also use this method to get the number of cells.)
