The battery is an essential part of the laptop and the battery must be of good quality that enhances the performance of laptops. People often face various problems concerning laptop batteries. Laptop batteries need great safety for better performance. The battery often expands and maybe explode due to neglection of precautions regarded to the batteries.
The laptop battery shows some signs before expanding. For instance, the laptop shuts down when the battery is 15% charge, then it starts shutting down at 30% or 60% charging. After this, the bump produces in the laptop battery as it means that the battery is expanding. The battery expansion can result in the big explosion of laptops.
Why is my laptop battery expanding? Your laptop battery can expand because of high temperature, overcharging the laptop, battery with impurities, low-quality battery, and electric fluctuations. The laptop battery can expand if you use your laptop by placing it on the glass desk. Therefore, it is recommended that there should be a smooth desk for your laptop.
The laptop batteries use a chemical reaction to generate power. When the battery does not complete the chemical reaction perfectly, this can result in the production of gases. This gas accumulation causes the battery to expand. The battery consists of electrodes and electrolytes which helps in the transfer of ions. Gases are produced due to oxidation and reduction of liquid electrolyte in the laptop batteries.
The anode and cathode depending on the material act as a catalyst for this process. These gases consist of carbon dioxide, oxygen, carbon monoxide, and some organic compounds. During the process of manufacturing, different chemicals are added to slow down the process of gas accumulation. But over time their efficiency reduces and battery expanding happens.

Why is my laptop battery expanding?
Overheating is the main cause of laptop battery expansion. It is recommended that you should not keep your laptop plug in all the time for charging. You should not run heavy applications on your laptop when the laptop is on charging. The good quality of the battery maintains the health of your laptop battery. The laptop battery has a fixed time limit and it damages after a fixed duration.
If your laptop battery is expanding then you should know about the reasons for battery expanding.
The reasons for laptop battery expanding are given below:
High temperature can make your laptop battery to expand
If the laptop is placed ata high temperature then it may result in the laptop battery expanding. It is recommended that you should avoid exposing your laptop battery to excessive heat. When you play heavy games on your laptop then this results in the overheating of your laptop battery. There should be a cool environment for your laptop to get rid of the overheating of laptop
It is recommended that you should use your laptop in an air-conditioned place. This will maintain the temperature of your laptop battery. You should not place your laptop under the sunlight because this is the high temperature for your laptop battery and it will expand due to high temperature.
If you are editing videos on your laptop then your laptop battery will overheat. Your laptop may slow or suddenly shut down due to overheating.
You should not place your laptop in the car because the temperature of the car is high and this can increase the heat on your laptop. This leads to the parasitic reaction between electrolyte and metal in the battery which causes gases to release.
When these gases do not release these results in the laptop battery expanding. Your laptop battery can expand if the air circulation is not better on your laptop. There should be a clear path for the air when the heat escapes from your laptop. It is recommended that you should place a book at the back of your laptop for the proper air circulation.
Physical damage to the laptop battery
The laptop battery is very sensitive and it needs great care for your laptop. You should use your laptop with great care and you should save your laptop from physical damage. It is recommended that you should protect your laptop from jerks as the points of battery disturb due to jerks.
The sparking often occurs when the laptop fell. If the internal layers of battery do not maintain separation due to defect or damage then your laptop battery can expand. The explosion often occurs due to physical damage in the laptop battery.
You should not throw your laptop on the floor because it will result in the battery expanding. You should use your laptop with good manners to save your battery life. The cells of the laptop battery can puncture due to physical damage and this will result in the laptop battery expanding.
The electrodes of the battery mechanically destroy during cell assemblage and this may result in the laptop battery expanding. The water is the major enemy of battery therefore you should keep your laptop away from the water.
You should save your laptop from crushing and dropping. If you observe smoke rising from your laptop battery then you should understand that this is an emergency case. You should stay away from your laptop because a big explosion could happen. It is recommended that you should place your laptop far from drinks and food, these can spoil your laptop battery.
Overcharging the laptop can cause the battery to expand
It is not good to overcharge your laptop because it can overheat your laptop. Your laptop will blow up and it also reduces the lifetime of your laptop battery. You should not charge your laptop overnight because it will cause your laptop battery to expand.
The laptop users often use their laptops while charging this overheats the laptops. If you see that your laptop battery has expanded then you should not charge your laptop. You should turn off your laptop when your laptop battery expanded.
It is not safe for your laptop when you continuously charge your laptop. You should not continuously plug in your laptop as it produces extra heat in your laptop. The laptop batteries don’t like extra heat, therefore, make your batteries happy by providing limited heat to them.
You can plug in your laptop until your laptop charges full but overcharging is not good for the laptop battery. Some people play games and watch videos while charging the laptop and also forget to remove it from charging. This results in the laptop battery expanding.
The cells in polymer batteries of laptops disturb due to the overflow of charges. Overcharging the laptop is dangerous as it can reduce the performance of your laptop. The overcharging of the laptop can result in the explosion.
When your laptop charged at 100% then you should unplug the charger of your laptop. In polymer batteries, the cells of battery charge to the voltage, therefore, if the cells of the battery get overcharged then the level of voltage will also increase.
Battery with impurities
During the manufacturing process of the battery, the metal that is used to make battery could have impurities in them. These impurities could lead to unwanted reactions between the electrolytes and the metals present inside the battery.
Due to this process, a lot of gases produced in the battery and this results in the laptop battery expanding. There are electrochemical cells in the laptop battery that provides power to the electrical devices. These impurities include iron, carbon dioxide, copper and aluminum. You should not charge a battery with USB.
These impurities can cause laptop battery expansion. The common batteries that are used in the laptops are nickel-metal hydride batteries and lithium-ion batteries. The characteristics of these batteries are different. There are about 100 poisonous gases in laptop batteries and these gases are fatal for the health of humans.
If you observe sparking on your laptop then you should stay away from your laptop because it may result in your laptop explosion. These gases can irritate your eyes, nasal way and skin. Polymer batteries are often used in the laptops and their cells frequently contain impurities during manufacturing.
The manufacturers of laptop batteries often use low-quality chemicals that are harmful to your laptop. These low-quality chemicals cause harmful chemical reactions that result in the laptop battery expanding.
Low-quality laptop battery
If the original laptop battery decays, people do not buy original batteries from genuine manufacturers. Laptop users often buy a first or second copy of the laptop batteries instead of the original battery. This is also the cause of laptop battery expansion.
These first or second copies of laptop batteries have a very short life span such as 8 months or 1 year. These batteries expand soon because they are not in the original form. Genuine batteries have a long lifetime.
If users use laptop batteries with great care then the life span of laptop batteries increases. The poor quality of cells that are used in batteries also results in the laptop battery expanding and you will notice that laptop battery will drain fast. These low batteries are designed with truncated stoichiometric proportions from anode to cathode.
There is particulate pollution from anode to cathode in the laptop batteries. This causes the laptop battery to expand. Sometimes this may result in an explosion. The battery manufacturers often replace the old cells with new cells in the battery and this is the major cause of laptop battery expanding.
Therefore, it is recommended that you should not buy a second copy of the laptop battery. You should buy the original laptop batteries from genuine manufacturers. If you charge your laptop with another charger instead of its original charger.
Then, this may result in your laptop battery expanding. Every laptop has a fixed amount of energy consumption, when the laptop is not connected with the original charger then it causes an overflow of charges. The overflow of charges results in the laptop battery expanding.
Leaving a laptop battery discharged
When you discharge your laptop battery, then you should not use it at 20% charging your laptop. You should not use your laptop until 0% battery. When the battery of your laptop discharge, you should charge your laptop. You should take care of your laptop for the longer life span of your battery.
If you buy a new laptop then you should not plug in your laptop until its charging become 0%. If you charge your laptop again and again then this can result in your laptop battery expanding. It is bad to leave a laptop battery discharged.
The deep discharge of laptop battery causes jellyroll misrepresentation of cells of battery due to gas accumulation. In a lithium-ion battery, when cells discharge deeply this results in an extremely de-intercalated position. There are cubbyholes in both cathode and anode of laptop battery.
The compact electrolyte interphase deposit of the battery crumbles and new electrolyte surface and electrode comes in interaction with each other. Then, the new solid electrolyte interphase deposit is shaped. The reactions take place in the laptop battery and result in gas development. These gases accumulate and exert pressure on the battery. This causes the laptop battery to expand.
Every laptop battery has a fixed life span and its life span decreases if it is not used with great care. There are fixed cycles of laptop battery that indicated the life of the battery. When the cycles of battery complete, then the battery does not work. You may notice that your laptop is beeping continuously when battery is about to die.
It is better to remove the old battery from the laptop because this old battery can cause laptop battery expansion. The low-quality cells that are used in laptop batteries are also the cause of battery expansion. You can even refurbish laptop battery with easy and simple steps.
These cells do not complete the chemical reactions perfectly and this results in the release of gases. The chemical reaction that takes place between electrolyte and electrodes cause the production of gases and heat.
This heat and gases expand inside the battery and this causes the laptop battery expansion. When the laptop battery expand it looks like a popcorn bag. It is recommended that you should remove the old battery from your laptop because there are chances of expanding in it. You should insert a new laptop battery to get rid of laptop battery expanding.
