When to Consider a Battery Replacement
Here are common signs indicating it might be time to replace your laptop battery.
| Symptom | Description |
|---|---|
| Short Run Time | The battery drains significantly faster than it used to, even after a full charge, lasting only an hour or less under light use. |
| Swelling or Bulging | The battery pack appears physically swollen or warped. This is a safety hazard and requires immediate replacement. |
| Charging Issues | The laptop does not charge to 100%, stops charging intermittently, or does not recognize the battery. |
| System Warnings | Your operating system (e.g., Windows) displays a “Consider replacing your battery” warning or indicates the battery is no longer functioning. |
| Unexpected Shutdowns | The laptop shuts down suddenly without a low battery warning, even when the reported charge level is not critically low. |
Estimated Battery Life
The following table provides conservative estimates of battery runtime for a Lenovo ThinkBook with this 45Wh battery under different usage scenarios.
| Usage Scenario | Estimated Runtime |
|---|---|
| Web Browsing & Email | 3 – 5 hours |
| Video Playback | 2.5 – 4 hours |
| Office Applications | 3 – 5 hours |
| High Performance / Gaming | 1 – 1.5 hours |
Note: These are estimates for a new battery. The actual runtime on your specific laptop may be less due to factors like aging hardware, background software activity, and screen brightness, which collectively consume more power compared to when the laptop was brand new.
