The Immediate Consequences of a Failing Battery
When your laptop battery begins to fail, you will notice several operational issues that affect daily use.
- Significantly Reduced Runtime: Your laptop may not hold a charge for more than a few minutes, effectively becoming a desktop computer tethered to a power outlet.
- Unexpected Shutdowns: The laptop can power off suddenly, even if the OS indicates remaining charge, leading to potential data loss.
- Inconsistent Charging: The battery might not charge to 100% or may drain rapidly even while plugged in.
Long-Term Risks to Your Laptop
Continuing to use a faulty battery can cause damage beyond the battery itself.
Potential Hardware Stress
A bad battery can cause irregular power delivery to the motherboard and other components. This voltage instability can, over time, contribute to premature wear on sensitive electronics.
Physical Swelling and Safety Hazards
One of the most serious risks is battery swelling. As lithium-ion cells degrade, they can produce gas, causing the battery to physically expand.
- Damage to the Chassis: A swollen battery can push against the laptop’s trackpad, keyboard, or case, causing permanent damage.
- Safety Risk: In extreme cases, a swollen battery poses a risk of leakage or thermal event. If you notice your laptop case is bulging, stop using it immediately.
Performance and Software Issues
The operating system and hardware are designed to work with a stable power source. A failing battery can disrupt this.
- Throttled Performance: Some systems may automatically reduce processor speed (throttle) to conserve the limited power available, making your laptop feel sluggish.
- System Errors: You may encounter frequent warnings from your OS about the battery’s health, and some diagnostic tools may fail to report accurate information.

Common signs include a runtime of less than an hour, the battery not charging fully, physical swelling, and the laptop shutting down without warning.
Is it safe to use my laptop with a swollen battery?
No. A swollen battery should be handled with care and replaced as soon as possible. Do not charge or use the device.
Can I replace the battery myself?
Many modern laptops have user-replaceable batteries. For models with internal batteries, replacement can be more complex and may require technical skill. Always refer to your device’s manual.
