1. A patient support apparatus having a removable battery, the patient support apparatus comprising:
a support frame with a patient support deck disposed on the support frame; and
a battery retention system coupled to the support frame and including:
a mount base,
a battery receiver pivotably coupled to the mount base for movement between a locked state and an unlocked state, the battery receiver defining a channel configured for engaging the battery and an aperture in communication with the channel,
an electrical interface coupled to the battery receiver for engaging the battery, and
a latch pawl interposed between the battery receiver and the mount base adjacent to the aperture, the latch pawl being arranged for movement between:
a retracted position in which the latch pawl is substantially outside the channel; and
an extended position in which the latch pawl is at least partially disposed in the channel;
wherein the latch pawl is engaged with the mount base such that pivoting movement of the battery receiver from the locked state to the unlocked state moves the latch pawl from the extended position toward the retracted position for permitting removal of the battery from the battery retention system.
