Buyers whose laptop requires a different voltage, capacity or physical form factor should look elsewhere.

Capacity and headroom

The 40Wh 2600mAh pack restores the original runtime Dell specified for these platforms. It comfortably handles everyday office work, web browsing and media playback on the supported 14 15 and 17 inch chassis. Heavy workloads that draw sustained high current will deplete the cell faster than the factory rating suggests.
