After purchasing a new laptop computer or battery for your laptop, we recommend that the battery be charged for no less than 24-hours. A 24-hour charge makes sure the battery is fully charged and helps with the battery's life expectancy. Once it is fully charged, you should not discharge it fully, if possible. Lithium-ion batteries (the type used in modern laptop computers) are strained, and may be weakened, when they are fully discharged.
Initialize a new battery. New batteries should be fully charged before their first use to obtain maximum capacity. Nickel-based batteries should be charged for 16 hours initially and run through 2-4 full charge/full discharge cycles, while lithium ion batteries should be charged for about 5-6 hours.
