5. Operating (First Use and Charging)
For optimal performance and longevity, follow these guidelines for initial use and charging:
- Initial Cycle: Upon first installation, discharge the new battery to 10-20% (do not let it reach 0%). Then, fully charge it to 95%. Repeat this discharge/charge cycle 3-4 times to 'wake up' the new battery and calibrate its capacity.

Proper maintenance can significantly extend your battery's life:
- Power Plan Optimization: Adjust your laptop's power plan settings to 'Power Saver'. In advanced power settings, reduce the processor state to 20% when on battery power.

- Disable Unused Features: Turn off Wi-Fi, Bluetooth, and other unnecessary features when not in use to conserve battery power.
- Storage: If storing the battery separately for a long time, ensure it is charged to over 80% at least once a month.
