When Should You 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 tasks. |
| Battery Won’t Charge | The battery percentage does not increase when plugged in, or the charger is recognized but the battery remains at 0%. |
| Swelling/Bulging | The battery pack is physically swollen, causing a bulge in the laptop’s case. This is a safety hazard and requires immediate replacement. |
| System Errors | Your operating system (e.g., Windows) reports a “battery error,” “consider replacing your battery,” or cannot detect the battery. |
| Inconsistent Charge | The reported charge percentage jumps erratically, or the laptop shuts down suddenly even though it shows significant charge remaining. |
| Old Age | Most lithium-ion batteries significantly degrade after 2-3 years of regular use, holding less than 60-70% of their original capacity. |
