How Long Should I Charge a New Laptop Battery?

A new laptop battery should not be charged for less than six hours if it is lithium ion-based, discharged completely then recharged again for three complete cycles. The exact time is takes to fully charge a battery varies and should be addressed in the manual.

Every time the battery is used, it wears out over time regardless of whether it is charged. However, new batteries should be charged fully, which ideally means leaving it on the charger overnight. It should be used until it completely discharged, then charged again. The cycle should be repeated three times to optimize the lifespan of the laptop's battery. Check the manual for more information on how long it takes the new battery to charge completely.
