When to Replace Your Battery
Consider replacing your laptop battery if you notice any of these common signs of battery degradation:

| Short Runtime | Battery drains significantly faster than when new, lasting less than 1-2 hours | Replace battery |
| Swelling/Bulging | Battery case appears swollen or distorted | Replace immediately for safety |
| Charging Issues | Battery won’t charge fully or charges intermittently | Replace battery |

Estimated Battery Life
Based on 79Wh capacity, here are conservative estimates of battery runtime for different usage scenarios:
| Usage Scenario | Estimated Runtime | Notes |
|---|---|---|
| Web Browsing | 4-6 hours | Light browsing, email, document editing |
| Video Playback | 3-5 hours | Streaming video at medium brightness |
| Office Work | 4-6 hours | Word processing, spreadsheets, presentations |
| Gaming | 1.5-2.5 hours | Demanding games at medium settings |
| Idle/Standby | 6-8 hours | Minimal activity with screen on |
Important Note: These are conservative estimates for a new battery. When installing any replacement battery in an older laptop, expect slightly shorter runtime compared to when the laptop was new due to increased software demands, background processes, and natural hardware aging that affects overall power efficiency.
