When to Replace Your Battery
Consider replacing your laptop battery if you notice any of these common signs:
| Symptom | Description |
|---|---|
| Short Battery Life | Battery drains significantly faster than when new, lasting less than 1-2 hours |
| Swelling/Bulging | Battery case appears swollen or distorted, creating gap between battery and laptop |
| Overheating | Battery becomes unusually hot during charging or normal use |

Estimated Battery Life
Based on 52.4Wh capacity with typical MSI laptop power consumption:
| Usage Scenario | Estimated Runtime |
|---|---|
| Web Browsing & Office Work | 4-6 hours |
| Video Streaming | 3-5 hours |
| Light Gaming | 1.5-3 hours |
| Intensive Gaming | 1-2 hours |
| Standby/Sleep Mode | 24-48 hours |
Note: These are conservative estimates for new batteries. Actual runtime may vary based on your specific laptop model, age of other components, screen brightness, background applications, and system settings. New batteries in older machines typically provide shorter runtime compared to when the laptop was brand new due to increased software demands and general system wear.
