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.
Use a wall mount charger or laptop adapter to charge the battery overnight. Charge at C/10 (ten percent of the battery's rated capacity per hour.) For example, if you have a 100 mAH battery, you would charge it at 10mA for 15 hours.
