6. First Use and Charging

To activate the battery's maximum capacity and ensure optimal performance, follow these initial charging instructions:

• Initial Activation: Use the battery until its charge level drops to approximately 5%, then fully charge it to 95%. Repeat this charge and discharge cycle 3-4 times. This process helps calibrate the battery and activate its full capacity.
• First Charge: For the very first use, it is recommended to fully charge the battery before using the laptop on battery power.

7. Maintenance and Storage

Proper maintenance and storage can significantly extend the lifespan of your laptop battery.

• Regular Use: For best results, use your laptop on battery power regularly rather than keeping it constantly plugged in.

• Avoid Constant Charging: While charging, avoid using the laptop for prolonged periods, as this might cause damage to the battery and reduce its capacity over time.
