My MacBook battery inflates: is it dangerous?

No matter what the model and model of the laptop, the inflated battery is one of the most common problems perplexing it.

MacBook is no exception. MacBook battery expansion is a common problem of MacBook aging. It starts with a bump on the front of your MacBook laptop. Soon, the touchpad began to have problems. Sometimes, it seems that you can only press it at the right angle. Soon, the bulge will become larger and you can't press the touchpad at all.

What causes the MacBook battery to expand?

There are many factors that can cause MacBook batteries to expand and burn. For example, the MacBook is overcharged, placed in an extremely hot space (such as a car glove box), physically damaged, and has fake and shoddy non-Apple batteries. Overcharging the MacBook Pro battery can lead to battery damage, resulting in an overreaction called "bleeding". This will cause the battery to form toxic gases in the membrane and layer, resulting in harmful gases inside.

MacBook battery expansion sometimes occurs. Due to manufacturer's defects or physically damaged batteries, hard impact sometimes endangers the battery shell, resulting in expansion or leakage.

First, the most common reason is that the battery is overcharged.

When the battery is charged, it continues to charge even though its capacity is already 100%. This leads to the chemical reaction between the electrode and the electrolyte, and then the released heat and gas expand inside the battery, eventually leading to expansion, and even in some serious cases, the battery liquid leaks.

It is not uncommon to accidentally charge the laptop all night and wake up to find that the battery is seriously inflated.

Second, if you put the MacBook Pro in a high-temperature environment, it may explode.

Exposure to high temperatures can also cause MacBook batteries to expand. The same problem can be caused by operating at a high temperature much higher than the recommended upper limit of the battery for a long time. This is particularly evident in smaller, thinner laptops, which cannot dissipate heat as quickly as larger, bulkier laptops with larger radiators or cooling fans. So when you go to work and leave your car, don't forget to take your MacBook with you!

Also, using a charger with the wrong voltage level can cause problems with the MacBook battery.

The best advice is to make sure you replace a faulty power adapter with exactly the same rated voltage.

Higher or lower voltages can still work, but this will cause the battery to become unstable, shorten its life, and may cause it to fail soon.

Finally, counterfeit, defective and non-Apple batteries are also one of the reasons.

Counterfeit, defective and non-Apple batteries can cause explosions and many battery problems. This means that the battery may not be able to use its own ions to power the MacBook, lack overcharge protection and easily run out of power.

How can I tell if my battery is inflated or faulty?

A clear way to determine whether the MacBook battery is inflated is to visually inspect the external area around the battery placement position.

The severe expansion will almost always endanger the MacBook shell in one way or another, and sometimes even cause other components to fail to work properly because the pressure exerted by the expanded battery affects the connection of the MacBook.

The expansion of the MacBook battery directly below the touch panel can cause the touch panel to loosen or even fall off completely.

In some cases, the expanded battery may also leak, resulting in a very pungent strong metal smell. This can easily damage other components of the MacBook and make it unusable.

If you smell burnt or metallic, it's best to stop all MacBook operations immediately and let professionals check.
