Help Me Choose: Battery
When choosing a laptop battery, it's important to consider how your laptop is used:
  • Is your laptop plugged in on your desktop most of the time?
  • Do you spend more time unplugged than plugged in?
  • Do size and weight matter when you travel?

Overview |   Compare Battery Life |   FAQ

In most cases, the number of cells inside a battery determines its size, weight and life between charges. A cell is essentially a smaller battery that is packaged with and connected to other cells to form one large battery. Generally, more the number of cells, more the power, weight and size a battery will have.

Finally, it’s important to note that battery life is always subject to demands and usage. For extended periods of use away from an outlet, you might want to consider purchasing a second battery for your laptop from Dell.com.
