Quick Answer
Yes, laptop batteries can swell due to various reasons, such as chemical reactions in aging lithium-ion cells, exposure to overheating, or physical damage. When a battery swells, it poses risks such as fire hazards, potential device damage, and safety concerns.
Why Do Laptop Batteries Swell?
Laptop batteries swell due to several factors:
Chemical Degradation: As lithium-ion batteries age, they can release gases that cause swelling.
Overcharging: Overcharging the battery or using defective charging circuits accelerates deterioration.
Heat Exposure: Using laptops in high-temperature environments can prompt swelling.
Physical Damage: A drop or puncture that causes an internal short may lead to swelling.
Manufacturing Defects: Low-quality or counterfeit batteries are more likely to swell.
How to Spot a Swollen Battery
Swelling can be identified by various signs:
- Physical Signs: Look for a bulging casing, warped trackpad or keyboard, and gaps in the chassis.
- Performance Issues: Loss of battery life, overheating, and unexpected shutdowns.
- Safety Warnings: Hissing noises and burning smells. If you observe smoke, stop using the device immediately.

Is It Safe to Use a Laptop With a Swollen Battery?
Using a laptop with a swollen battery is not safe:
- Immediate Risks: There could be leakage, fire, or explosion risks.
- Long-term Risks: Permanent damage to internal components may occur.
- Myth-busting: Leaving your laptop plugged in will not fix swelling issues.
