Expected Battery Life
Based on 41Wh capacity with typical Fujitsu laptop power consumption:
| Usage Scenario | Estimated Runtime |
|---|---|
| Web Browsing & Email | 3-4 hours |
| Document Editing | 3.5-4.5 hours |
| Video Playback | 2.5-3.5 hours |
| Gaming | 1.5-2.5 hours |
| Standby/Sleep | 24+ hours |
Note: These are conservative estimates for new batteries in older systems. Actual runtime may be shorter than when your laptop was new due to increased software demands and hardware aging.
