Even though the top cover had to be removed to get to it, the battery comes out quite easily.

The 14.8 V, 29 Wh battery is one of the well-noted shortcomings of the Inspiron Duo. Though Dell claims it will last 3 hours and 57 minutes, Engadget's review warns users of a sub-3 hour battery life.

Living up to its claimed battery life would still leave the Inspiron Duo well behind most other devices currently on the market, many of whom boast battery lives over 7 hours.
