How to extend the life of the laptop battery:

• 1. When using the laptop battery for the first time, charge it for 12 hours to fully activate the battery.
• 2. Maintaining the power of lithium-ion battery at 10%-90% is beneficial to protect the battery.
• 3. When plugged in for a long time, set it to over 80% before recharging, or enable the battery charging protection scheme that comes with the computer.
• 4. Unnecessary software, usb hardware, etc. can be turned off when using the battery.
• 5. Pay attention to the working environment of the battery, keep good ventilation and heat dissipation.
• 6. Calibrate the battery once every 3-4 months.
• 7. Ensure that the notebook computer has a stable voltage, and try to avoid connecting the notebook power adapter and high-power electrical appliances (such as air conditioners, refrigerators, washing machines) to the same power outlet.
• 8. Use the original adapter to charge.
