Using a Second Battery Pack
You can purchase a second rechargeable battery pack. With two battery
packs, you can extend the time that you use your computer with battery
power. When using two battery packs, the battery pack you insert first
charges first. The battery pack you insert second charges when the first
battery pack is 85 percent full. You can monitor which battery pack is
charging by observing the battery indicator lights.
