When to Consider Battery Replacement
If you’re experiencing any of the following issues with your current laptop battery, it may be time for a replacement:
| Symptom | Description | Indication |
|---|---|---|
| Short Battery Life | Battery drains significantly faster than when new, lasting less than 1-2 hours under normal use | Battery capacity has degraded below practical levels |
| Swelling/Bulging | Battery case appears swollen or distorted, may cause trackpad/keyboard lifting | Immediate replacement required for safety |
| Charging Issues | Battery won’t charge fully, charges intermittently, or doesn’t hold charge | Battery cells or circuitry failing |
| System Warnings | Laptop displays “Consider replacing your battery” or similar messages | System detects battery health below threshold |
| Unexpected Shutdowns | Laptop turns off suddenly even when battery indicator shows remaining charge | Battery cannot deliver required power |
| Age Factor | Battery is 2-3 years old with regular use | Normal lifespan degradation expected |
Estimated Battery Life by Usage
Based on 48Wh capacity with compatible ASUS laptops (conservative estimates):
| Usage Scenario | Estimated Runtime | Power Consumption Level |
|---|---|---|
| Web Browsing/Email | 4-6 hours | Medium |
| Document Editing | 5-7 hours | Low-Medium |
| Video Streaming | 3-5 hours | Medium-High |
| Gaming | 1.5-2.5 hours | High |
| Video Conferencing | 3-4 hours | Medium-High |
| Standby/Sleep Mode | Multiple days | Very Low |
Important Note: These estimates are for new batteries used with older hardware. Actual battery life may be shorter than when your laptop was new due to increased power demands from software updates, operating system changes, and natural hardware aging. Screen brightness, background applications, and wireless connectivity also significantly impact battery duration.
