The perimeter is established by a plurality of sidewalls and endwalls of the battery pack enclosure. ## Claims ### Claim 1 A method of securing a battery pack to an electrified vehicle, comprising: moving a battery pack enclosure relative to a portion of an electrified vehicle to transition a retention feature from a disengaged position to an engaged position, the retention feature in the engaged position at least partially securing the battery pack enclosure to the electrified vehicle, the retention feature in the engaged position laterally within a perimeter of the battery pack enclosure, the perimeter established by a plurality of sidewalls and endwalls of the battery pack enclosure; and further securing the battery pack to the electrified vehicle using a fastener that is positioned outside of the perimeter. ### Claim 2 (depends on 1) The method of claim 1, wherein the retention feature includes a protrusion and a bracket, the protrusion contacting a pocket floor of the bracket when the retention feature is in the engaged position. ### Claim 3 (depends on 1) The method of claim 1, wherein the portion is an underbody of the electrified vehicle, and the moving is a moving of the battery pack enclosure relative to the underbody. ### Claim 4 (depends on 3) The method of claim 3, wherein the moving is a horizontal movement of the battery pack enclosure relative to the underbody. ### Claim 5 (depends on 1) The method of claim 1, wherein the moving is a relative movement of the battery pack enclosure toward a front of the electrified vehicle. ### Claim 6 (depends on 3) The method of claim 3, wherein the moving is a vertical movement of the battery pack enclosure relative to the underbody. ### Claim 7 (depends on 1) The method of claim 1, wherein the retention feature includes a protrusion having a neck portion extending along an axis from a surface to a head portion that is enlarged relative to the neck portion, wherein the neck portion is received within a slot of a bracket during the moving such that at least a portion of the bracket is positioned between the head and the surface when the retention feature is in the engaged position. ### Claim 8 (depends on 7) The method of claim 7, wherein the bracket includes a floor and a flange extending from the bracket, the flange angled relative to the floor, and further comprising bending the flange as the protrusion moves through the slot to the engaged position with bracket. ### Claim 9 (depends on 1) The method of claim 1, wherein the retention feature includes a protrusion extending along an axis from a surface, the protrusion having a post and at least one tang extending from the post in a direction transverse to the axis, wherein a bracket is positioned between the at least one tang and the surface when the retention feature is in the engaged position. ### Claim 10 (depends on 1) The method of claim 1, wherein the retention feature includes a bracket and a protrusion, the bracket having a pocket with a floor, the protrusion having a tab spaced from a surface, wherein the floor of the pocket is positioned between the tab and the surface when the retention feature is in the engaged position. ### Claim 11 (depends on 1) The method of claim 1, wherein the retention feature includes a protrusion that extends from the battery pack enclosure, and a bracket that is directly attached to an underbody of the electrified vehicle. ### Claim 12 (depends on 1) The method of claim 1, wherein the retention feature includes a protrusion that extends from an underbody of the electrified vehicle, and a bracket that is directly attached to the battery pack enclosure. ### Claim 13 (depends on 1) The method of claim 1, wherein the retention feature includes a protrusion that is directly attached to a lid of the battery pack enclosure, or a bracket that is directly attached to the lid. ### Claim 14 (depends on 1) The method of claim 1, wherein the fastener is a mechanical fastener. ### Claim 15 A securing method, comprising: moving an enclosure of a battery pack relative to a portion of an electrified vehicle to transition a retention feature to an engaged position where the enclosure is secured to the electrified vehicle, the retention feature laterally inside a perimeter of the enclosure that is established by a plurality of sidewalls and endwalls of the enclosure; and fastening the enclosure to the portion at a position outside the perimeter. ### Claim 16 (depends on 15) The method of claim 15, further comprising fastening using at least one mechanical fastener. ### Claim 17 A securing method, comprising: securing a battery pack relative to a portion of an electrified vehicle by engaging a retention feature inside a perimeter of a battery pack enclosure, and by fastening the battery pack enclosure to the portion with at least one fastener outside the perimeter, the perimeter established by a plurality of sidewalls and endwalls of the battery pack enclosure. ### Claim 18 (depends on 17) The method of claim 17, wherein the at least one fastener is a mechanical fastener.
