Does a MacBook Pro battery swell when it fails?

The MacBook Pro, a flagship product of Apple Inc., is renowned for its exceptional performance and sleek design, making it a favorite among users worldwide. However, recent reports of battery swelling in MacBook Pro models have raised concerns among users. Battery swelling not only affects the device's aesthetics and usability but also poses potential safety risks.

This article delves into the causes, signs, solutions, and preventive measures for MacBook Pro battery swelling, providing a comprehensive guide for users.

Causes of MacBook Pro Battery Swelling

Battery Aging: Lithium-ion batteries naturally degrade over time due to repeated charging and discharging cycles, leading to internal chemical reactions that cause electrode materials to expand.

Overcharging: Prolonged connection to a power adapter can result in overcharging, generating excessive heat and gas, which may cause the battery to swell.

High Temperatures: Using or storing the MacBook Pro in high-temperature environments accelerates internal chemical reactions, increasing the risk of swelling.

Physical Damage: Accidental drops or impacts can damage the battery's internal structure, leading to swelling.

Manufacturing Defects: In rare cases, manufacturing defects in the battery can cause premature swelling.

Signs of MacBook Pro Battery Swelling

Visible Deformation: The device's body may show noticeable distortion, such as a bulging trackpad or uneven keyboard.

Difficulty in Opening/Closing: The screen may not open or close smoothly, possibly accompanied by unusual noises.

Trackpad Malfunction: Pressure from the swollen battery can cause the trackpad to become unresponsive or fail completely.

Keyboard Issues: Some keys may become unusable due to the deformation of the device's body.

Excessive Heat: The device may overheat abnormally, even when not running high-performance applications.

Solutions for MacBook Pro Battery Swelling

Immediate Cessation of Use: Stop using the device immediately upon noticing signs of battery swelling to avoid potential safety hazards.

Disconnect Power: If the device is connected to a power adapter, disconnect it promptly.

Avoid Pressure: Do not attempt to press or squeeze the swollen area, as this could cause the battery to rupture or leak.

Proper Storage: Store the device in a cool, dry, and well-ventilated area, away from flammable materials.

Contact Apple Support: Reach out to Apple's official support or visit an authorized service provider for professional assistance.

Backup Data: If safe, back up important data promptly to prevent potential loss.

Understand Warranty Policies: Check if the device is still under warranty and familiarize yourself with relevant repair or replacement policies.

Preventive Measures for MacBook Pro Battery Swelling

Proper Charging: Avoid prolonged overcharging; it's advisable to charge when the battery level drops below 20% and disconnect at 80-90%.

Temperature Control: Avoid using or storing the device in high-temperature environments; maintain an optimal operating temperature.

Regular Checks: Periodically check the battery's health status through system reports or third-party tools.

System Updates: Keep the macOS updated to ensure optimal battery management functionality.

Moderate Usage: Avoid prolonged high-load operations; allow the device adequate rest periods.

Correct Storage: For long-term storage, maintain the battery at around 50% charge and store in a cool, dry place.

Use Genuine Accessories: Use Apple-certified chargers and batteries to ensure compatibility and safety.

Repair Options for MacBook Pro Battery Swelling

Official Repair: Apple's official battery replacement service offers guaranteed quality but at a higher cost.

Authorized Service Providers: Services from Apple-authorized providers may offer better value for money compared to official repairs.

Third-Party Repair: Non-official repair shops may offer cheaper services, but choose carefully to ensure quality.

DIY Replacement: Technically skilled users can purchase compatible batteries for self-replacement, though this carries some risk.

 

Safety Precautions for MacBook Pro Battery Swelling

Keep Away from Fire: Swollen batteries pose a fire risk; keep them away from open flames and high temperatures.

Avoid Puncturing: Never attempt to puncture or disassemble a swollen battery, as this can trigger dangerous chemical reactions.

Use Protective Gear: If handling a swollen battery is necessary, wear protective gloves and glasses.

Proper Disposal: Dispose of swollen batteries according to local electronic waste regulations.

Ensure Ventilation: When handling swollen batteries, ensure the area is well-ventilated.
