When to Replace Your Battery
Consider replacing your laptop battery if you notice any of these common signs of battery degradation:
| Symptom | Description |
|---|---|
| Short Runtime | Battery drains significantly faster than when new, lasting less than 1-2 hours under normal use |
| Swelling/Bulging | Battery case appears swollen or distorted, which can be a safety hazard |
| Charging Issues | Battery won’t charge fully, charges very slowly, or doesn’t hold charge |
| System Warnings | Laptop displays “Consider replacing your battery” or similar messages |
| Unexpected Shutdowns | Computer shuts down suddenly even when battery indicator shows remaining charge |
| Age | Battery is 2-3 years old with regular use, as lithium-ion batteries naturally degrade over time |
Expected Battery Life
Based on the 54Wh capacity, here are conservative estimates of expected battery runtime:
| Usage Scenario | Estimated Runtime |
|---|---|
| Web Browsing & Email | 4-6 hours |
| Document Editing | 5-7 hours |
| Video Streaming | 3-5 hours |
| Gaming | 1.5-3 hours |
| Standby/Sleep Mode | 24+ hours |
| Mixed Typical Use | 4-5 hours |
Important Note: These are conservative estimates for a new battery used with older hardware. Actual battery life may be shorter than when your laptop was new due to increased power demands from software updates, hardware aging, and background processes.
