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% full. You can monitor which battery pack is charging 
by observing the battery indicator lights.
