Installation and usage instructions:

1. Before replacing the battery, be sure to turn off the power first and then remove the charger plug. Replacing the battery during the startup process may pose a safety hazard.
2.After removing the original battery, press the power button continuously for 10 seconds without releasing it. Release the remaining power and static electricity on the motherboard before replacing the new battery.
3. Before installing a new battery, confirm the positive and negative poles of the battery, especially the built-in battery, and be careful not to plug it in incorrectly.

Regarding Capacity:

Lithium batteries are consumables, and it is normal for their capacity to fluctuate by around+5% due to factors such as inventory time and usage environment.

How to properly charge laptop batteries?

It is advisable to avoid waiting until the battery is fully charged before recharging, as this can put a lot of pressure on the battery and cause damage. A more feasible approach is to charge when there is around 20-30% remaining battery. In fact, there is a limit to the number of times a laptop battery can be used up/charged, and using it all up before recharging will greatly shorten the battery life. At the same time, batteries should be charged in a relatively dry place, and attention should also be paid to heat issues, which is the enemy of batteries.
