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.
