❤️How to use the battery properly to ensure longer battery life:

1. When the battery is first used, discharge it to 5%(not 0%), then charge it to 100%, cycling 3-4 times to activate the battery's maximum capacity.

2. In daily use, when the battery level drops to 15%, please charge it immediately. Otherwise, the battery life is shortened and battery damage is caused.

3. If the battery is not used for a long time, it is better to charge the battery to at least 50% capacity. Otherwise, it will not be able to charge again.

4. To keep the battery in top condition, replace the battery by fully discharging it to 15% and charging it to 100% every 2 months.

5. Don't unplug the battery while charging, and it's best to turn off the laptop while charging. When using batteries, do not connect adapters for

long periods of time. It may damage the battery.

6. If your laptop doesn't charge or doesn't fully charge, the adapter may not be compatible with the laptop or the adapter may be damaged. Please

close your laptop and try again or replace it with the correct adapter.
