MacBook Battery Swelling: Signs, Prevention, and Remedies

macbook swollen battery

When a MacBook battery begins to swell or bulge, it's not just a minor inconvenience—it's a warning sign that demands immediate attention.


Signs of MacBook Battery Swelling

The first indication that your MacBook battery may be swelling manifests as a noticeable bulge beneath the keyboard. This bulge can cause some keys to protrude, disrupting their alignment with the rest of the keyboard. Additionally, you may observe the seams along the edges of your MacBook starting to separate. As a result, the lid may no longer close properly, and the keyboard and trackpad might exhibit irregular functionality. Moreover, your MacBook may struggle to sit evenly on a flat surface, prone to rocking due to the uneven battery expansion.


Why MacBook Batteries Swell

Understanding the underlying reasons behind MacBook battery swelling is crucial for effective prevention and management. Generally, two primary factors contribute to this issue:


Aging Batteries

Over time, the chemical reactions within a battery degrade, leading to the accumulation of gases. As these gases build up, they cause the battery to swell. This aging process is a natural phenomenon exacerbated by frequent charging cycles.


Faulty Battery Components

In some cases, a battery may swell due to faults within its internal structure. Specifically, membranes designed to separate different layers of the battery fail to perform their function adequately. Consequently, these layers come into contact with each other, resulting in swelling.


Responding to Bulging Batteries

When you detect a bulging battery on your MacBook, it's crucial to take prompt and decisive action to mitigate potential risks. Here's what you should do:


  1. Disconnect Power: Immediately unplug your MacBook from the mains power source to prevent further charging, reducing the risk of overheating or combustion.

  2. Ensure Safety: Move your MacBook to a cool, non-flammable surface to minimize potential hazards.

  3. Backup Data: Safeguard your valuable data by copying it onto an external hard drive or USB stick, ensuring no critical information is lost during the battery replacement process.

  4. Shutdown: Power down your MacBook to prevent any further strain on the compromised battery.

  5. Seek Professional Assistance: Refrain from attempting a DIY fix and reach out to Apple support or a reputable repair shop without delay.

Preventing MacBook Battery Swelling

Prevention is undoubtedly the most effective approach to combatting a swollen battery. Follow these proactive measures to safeguard your MacBook Pro:


  • Avoid Overcharging: Limit exposure to prolonged charging periods to mitigate heat build-up.

  • Manage Battery Cycles: Regularly calibrate your battery as per Apple's recommendations to optimize performance.

  • Use Correct Charger: Stick to the original charger provided with your MacBook Pro to ensure compatibility and safety.

  • Maintain Cool Environment: Prevent exposure to high temperatures, as heat exacerbates battery swelling.

  • Stay Updated: Keep your MacBook Pro's software updated to benefit from enhancements aimed at battery performance.
