If you are looking to upgrade the battery on your AR.Drone for extended flight time be sure to consider the following:
1) A larger capacity battery (i.e. > 1,000 mAh) is likely to weigh more than the original; and
2) Going for a larger voltage battery could damage internal components of the AR.Drone so look for replacements that maintain the 11.1V peak voltage.
If you have already sourced a larger battery for your AR.Drone, the following video tutorial shows you how to fit the relevant connectors.
