How to Prolong Lithium-Based Batteries
A lithium-ion battery in use typically lasts between 18-24 months. Follow the below
recommendations to prolong your battery life cycle.
Initial Use or After Prolonged Storage Period
Your new battery comes in a discharged condition and must be charged before use. Upon initial use
(or after prolonged storage period) the battery may require two or three charge/discharge cycles before
achieving maximum capacity. To do so, unplug the AC adapter, turn off power management features
(through BIOS Setup), and turn on the system. Once the battery is discharged (maximum 95% depth-
of-discharge recommended), plug in the AC adapter and recharge the battery (without interruption).
