When to Replace Your Laptop Battery
Consider replacing your battery if you notice any of the following signs:
| Symptom | Description |
|---|---|
| Short Battery Life | The laptop powers off much sooner than it used to, even after a full charge, and doesn’t last through typical work sessions. |
| Battery Not Charging | The battery percentage does not increase when the adapter is plugged in, or it gets stuck at a certain percentage. |
| Swelling/Bulging | The battery pack has visibly expanded, causing the laptop case to warp or the touchpad to push up. This is a safety hazard. |
| Inconsistent Charge | The reported charge level fluctuates wildly or the laptop shuts down suddenly despite showing ample charge remaining. |
| System Warnings | Your operating system (e.g., Windows) displays a warning message recommending battery replacement. |
| Old Age | Most lithium-ion batteries significantly degrade after 2-3 years of regular use, leading to reduced performance. |
