When Should You Replace Your Battery?
Here are common signs indicating it’s time for a battery replacement:
| Symptom | Description |
|---|---|
| Short Runtime | Battery drains significantly faster than original capacity, lasting less than 1 hour |
| Swelling/Bulging | Battery case appears swollen or distorted – replace immediately for safety |
| Not Charging | Battery won’t charge fully or stops charging at certain percentage |
| System Warnings | Laptop displays “Consider replacing your battery” or similar messages |
| Age | Battery is 2-3 years old with noticeable performance degradation |
| Random Shutdowns | Laptop turns off unexpectedly even with reported charge remaining |
Expected Battery Life
Based on 28Wh capacity with typical Fujitsu LifeBook power consumption:
| Usage Scenario | Estimated Runtime |
|---|---|
| Web Browsing & Email | 2-3 hours |
| Word Processing | 2.5-3.5 hours |
| Video Playback | 1.5-2.5 hours |
| Gaming | 1-1.5 hours |
| Standby/Sleep | 8-12 hours |
Note: These are conservative estimates for replacement batteries. New batteries in older systems typically provide 70-80% of the original runtime due to increased software demands and hardware aging.
