O que fazer se a bateria do seu MacBook estiver inchando?

A swollen MacBook battery is a serious issue that should never be ignored. It indicates irreversible damage to the lithium battery and poses a potential safety risk, including fire or explosion. In this guide, we'll walk you through the causes, risks, and proper steps to safely handle a swollen MacBook battery — whether you're planning to replace it or temporarily use your MacBook without it.

What causes MacBook battery bulging?

MacBook uses lithium polymer batteries. When used for a long time, too many charge and discharge cycles, high temperature or improper charging, chemical reactions may occur inside these batteries, producing gas, which eventually leads to battery bulging.

Bulging is an irreversible battery damage, which means that the battery is on the verge of being "scrapped".

Can I still use a bulging battery?

You can't continue to use it!
Although bulging batteries can sometimes "light up the device", this is a completely dangerous fluke mentality. Bulging batteries have a very high risk of fire, especially in the following situations:

Poke the battery when disassembling the machine by yourself;

The battery is compressed or heated;

Continue to charge or use it at high load.

Therefore, if you find that the battery is bulging, it is recommended to stop using the device immediately to avoid further damage or personal injury.

What Should You Do with a Swollen Battery?

Option 1: Replace the MacBook Battery (Recommended)

The safest and most effective solution is to replace the swollen MacBook battery. You can:

• Visit an Apple Authorized Service Provider for a genuine battery replacement.

• Go to a trusted third-party repair shop that offers high-quality battery replacements (ensure they provide a warranty and use certified, safe parts).

Once replaced, your MacBook should return to normal performance and battery life.

Option 2: Remove the Battery and Use Your MacBook as a Desktop

If you’re not ready to replace the battery immediately, a temporary solution is to:

• Have the swollen battery professionally removed,

• And run your MacBook directly on AC power — effectively using it like a desktop.

Important Notes:

• This should only be done by professionals.

• Some MacBook models may reduce performance or limit features without a battery.

• Never carry the device without the battery secured inside.

Option 3: Replace the Battery Yourself by Purchasing Online

If you have technical skills and are comfortable with DIY repairs, you can purchase a compatible MacBook battery online and replace it yourself.

• Look for high-quality replacement batteries from reputable online sellers (make sure it’s compatible with your exact MacBook model).

• Use a detailed MacBook battery replacement guide or video tutorial to ensure proper disassembly and installation.

• Use the right tools (like pentalobe screwdrivers and suction cups) to avoid damaging your MacBook.

Important Warnings:

• DIY battery replacement carries some risk — especially with a swollen lithium battery, which can be dangerous if punctured.

• Only attempt this if the battery swelling is minimal and you have prior repair experience.

• Always work in a ventilated area and avoid using sharp tools near the battery.

If the battery is severely swollen or pressing against the case, it is safer to let a professional handle the removal.

Never Puncture a Swollen Battery!

Some users may consider "releasing the gas" by poking a hole in the battery.
This is extremely dangerous. Do not do it.

Puncturing a lithium battery can result in:

• Internal short circuits

• Fire or explosion

• Toxic gas release

• Severe burns or property damage

Swollen batteries are not balloons — they cannot be safely deflated. They must be replaced or professionally disposed of.

How to Dispose of a Swollen MacBook Battery Safely

Swollen lithium batteries are considered hazardous waste and should never be thrown in the trash.
Instead:

• Take the battery to a local electronic recycling center,

• Or drop it off at a certified Apple Store or repair center.

Store the battery in a cool, dry place in a fireproof bag if you can’t dispose of it immediately.

How to Prevent MacBook Battery Swelling in the Future

To extend battery life and avoid future swelling, follow these tips:

• Avoid keeping your MacBook plugged in 24/7.

• Use genuine or certified chargers and cables.

• Don’t let the battery drain to 0% frequently.

• Keep your device in a cool environment — heat is a major battery killer.

• If you’re storing your MacBook for a long time, keep the battery at 40–60% charge.

Avisos importantes:

• A troca da bateria por conta própria apresenta alguns riscos — especialmente com uma bateria de lítio inchada, que pode ser perigosa se perfurada.

• Tente fazer isso somente se o inchaço da bateria for mínimo e você tiver reparos anteriores experiência.

• Trabalhe sempre em uma área ventilada e evite usar ferramentas afiadas perto da bateria.

Se a bateria estiver muito inchada ou pressionando o gabinete, é mais seguro deixar um profissional cuidar da remoção.

Nunca perfure uma bateria inchada!

Alguns usuários podem considerar "liberar o gás" fazendo um furo na bateria.
Isso é extremamente perigoso. Não faça isso.

Perfurar uma bateria de lítio pode resultar em:

• Curto-circuito interno

• Incêndio ou explosão

• Liberação de gases tóxicos

• Queimaduras graves ou danos materiais

Baterias inchadas não são balões — elas não podem ser esvaziadas com segurança. Elas devem ser substituídas ou descartadas profissionalmente.

Como descartar uma Bateria de MacBook inchada com segurança

Baterias de lítio inchadas são consideradas resíduos perigosos e nunca devem ser descartadas no lixo.
Em vez disso:

• Leve a bateria a um centro de reciclagem de eletrônicos local,

• Ou deixe-a em uma Apple Store ou centro de reparos certificado.

Guarde a bateria em um local fresco e seco, em um saco à prova de fogo, caso não possa descartá-la imediatamente.

Como evitar que o MacBook Inchaço da Bateria no Futuro

Para prolongar a vida útil da bateria e evitar o inchaço futuro, siga estas dicas:

• Evite manter seu MacBook conectado à tomada 24 horas por dia, 7 dias por semana.

• Use carregadores e cabos originais ou certificados.

• Não deixe a bateria chegar a 0% com frequência.

• Mantenha seu dispositivo em um ambiente fresco — o calor é um grande destruidor de bateria.

• Se você for guardar seu MacBook por um longo período, mantenha a bateria com 40 a 60% de carga.
