How do I charge my new battery?

1. For transport safety reasons, new batteries are usually not fully charged. When you receive the battery, please use the remaining energy in the battery until the laptop turns off. Then fully charge the battery and use all the power. Then fully charge it. Repeat the cycle three times to activate the battery.

2. If you store the battery for a long time, the battery requires three to four charge and discharge cycles to achieve maximum efficiency.

3. Sometimes when the battery is charged for the first time, the indicator on the device shows that the battery is fully charged after 10-15 minutes of charging. This is normal for "batteries", just remove the battery from the device, put it back in and charge it.

How to extend the battery life of a laptop?

1. Please charge the battery in time. Many of us like to charge when your laptop's battery is empty, which significantly shortens the battery life. Never discharge your laptop battery under 20% charge if possible.

2. The most important point is to fully discharge and charge the battery every month. The easiest method of discharging is to turn on the device until the battery is empty, and then fully charge it.

3. When you are not using the laptop, you should turn it off. The laptop never turns off, often in standby mode, the battery life of these laptops is often very low.

4. For laptops that often do not turn on, we should also charge the laptop about every half months. If the laptop does not turn on for a long time and does not work, the battery activity also decreases.

5. If you do not use the battery for more than a month, it is recommended to remove the battery from the device and store it in a dry and cool place.
