Disconnect the fan wires by pulling on the connector while pushing on its sides with the spudger.

These connectors are extremely fragile. Make sure to not use any metal tools during this and the following steps.

You can leave the wires plugged in since their length allows the removal of the fan assembly while connected. This step just makes the process of further steps more manageable.

Lift the fan assembly and place it on the battery, bottom-up.
