1. A motorized window treatment comprising:
a roller tube having a longitudinal axis and a cavity;
a flexible material that is attached to the roller tube, the flexible material operable between a raised position and a lowered position via rotation of the roller tube;
a motor drive unit disposed within the cavity of the roller tube, the motor drive unit comprising:
a motor drive unit housing,
a motor configured to rotate the roller tube to operate the flexible material between the raised position and the lowered position,
a battery compartment that is configured to hold a plurality of batteries for powering the motor drive unit, and
a cap that is configured to be removably secured to an end of the motor drive unit and to retain the plurality of batteries within the battery compartment; and
a first mounting bracket configured to be attached to a structure and to rotatably support an end of the roller tube, and wherein the first mounting bracket comprises a stationary portion and a translating portion, the translating portion configured to translate the motorized window treatment between an operating position and an extended position, and wherein the translating portion comprises an attachment member that defines an attachment aperture, the attachment member configured to receive a portion of the motor drive unit housing, and wherein the portion of the motor drive unit housing is accessible via the attachment aperture when the motorized window treatment is in the extended position, and wherein the plurality of batteries are configured to be removed from the battery compartment of the motor drive unit via the attachment aperture,
wherein, when the motorized window treatment is in the operating position, the motor drive unit housing is aligned with the stationary portion of the first mounting bracket and a second mounting bracket, and wherein, when the motorized window treatment is in the extended position, the portion of the motor drive unit housing is accessible via the attachment aperture while the roller tube is supported by the first mounting bracket and the second mounting bracket.
