When Should You Replace Your Laptop Battery?
Consider replacing your battery if you notice any of the following signs:
| Symptom | Description |
|---|---|
| Short Run Time | The battery drains significantly faster than it used to, even after a full charge. |
| Swelling or Bulging | The battery pack appears physically swollen or distorted. Discontinue use immediately. |
| Charging Issues | The laptop does not charge to 100%, or it stops charging intermittently. |
| System Warnings | Your operating system (e.g., Windows) displays a “Consider replacing your battery” warning. |
| Unexpected Shutdowns | The laptop turns off suddenly even when the battery indicator shows remaining charge. |
Estimated Battery Life
Below are conservative estimates for the 74Wh battery under different usage scenarios:
| Usage Scenario | Estimated Runtime |
|---|---|
| Web Browsing & Office Tasks | 4 – 6 hours |
| Video Playback | 3 – 5 hours |
| Gaming | 1 – 2 hours |
| Light Use (Idle/Standby) | 6 – 8 hours |
Please note: These are estimates for a new battery. When paired with your older laptop, the actual runtime may be less than when the laptop was brand new due to increased power demands from aged hardware and modern software.
