This step is completely unnecessary! There is no need to disconnect the battery for replacing the speakers for NP900X4B-A02.
BTW, disconnecting the battery is quite tricky. As you can see in the photo, when trying to pull out the connector, it bumps into the connector next to it (on the left). The cables are stiff and you have to exert considerable force and risk hitting the cables with the tool you are using while disconnecting the battery. If you DO have to disconnect the battery for any reason, first unplug the connector to the left, under the battery's ribbon wire cable.
