Start by removing the bottom ring. If the droid can still be turned on, open the Sphero app to connect and turn it on to extend its central and side legs, then remove the bottom ring.
Otherwise, you'll have to first remove the side legs. Use a Jimmy to pop up the covers of the arms and remove the 3 screws holding the arms. Slowly remove the arms and then the bottom ring.

Turn off the droid to return the central and side legs to their original positions.

Use a Jimmy or another prying tool to remove the two vertical back panels. Remove the screws holding the back of the droid.

Slowly work your way to separate the back of the droid from the front. Now you should have access to the internal components.

Carefully unplug and remove the original battery from the slot. The original battery connector is proprietary and needs to be spliced into the new battery. Cut the connectors from both batteries. Splice the original battery connector with the replacement battery.
Insert the new replacement battery into the slot.
Plug in the battery connector.
