Understanding a Swollen Battery

A swollen battery is caused by gas building up inside the cells, a condition known as outgassing. This is a sign of battery failure and can be triggered by factors like age, physical damage, exposure to extreme temperatures, or using a faulty charger.

Is It Safe to Remove the Swollen Battery?

Yes, removing a swollen battery is the correct first step for safety. However, running the laptop solely on AC power afterwards comes with important caveats.

Risks of Using AC Power Without a Battery

• No Power Backup: A sudden power outage will immediately shut down your laptop, potentially leading to data loss or file corruption.
• Potential for Power Surges: The battery acts as a buffer against fluctuations in AC power. Without it, your laptop’s internal components may be more vulnerable to damage from power surges.
• Reduced Portability: Your laptop becomes a desktop computer, tethered to a power outlet.
• Possible Incompatibility: Some older laptop models may not boot or function correctly without a battery installed.

Safe Steps to Remove a Swollen Battery

If you must handle the battery yourself, follow these precautions:

1. Power Down and Unplug: Turn off the laptop and disconnect it from the AC adapter.
2. Use Protective Gear: If possible, wear gloves and safety glasses.
3. Work in a Well-Ventilated Area: Move to a space with good air circulation.
4. Gently Remove the Battery: Do not puncture, bend, or apply excessive force to the battery. If it’s stuck, do not pry it aggressively.
5. Proper Disposal: Do not throw the swollen battery in the trash. Take it to a designated electronics or battery recycling centre.

Important: If the battery is severely swollen, difficult to remove, or shows signs of leaking, stop immediately and consult a professional repair service.

The Best Solution: Replace Your Battery

The only reliable and safe long-term solution is to replace the swollen battery with a new, high-quality compatible replacement. This restores your laptop’s full functionality, portability, and built-in surge protection.
