1. A blister pack for packaging batteries, comprising: a plurality of batteries;a blister card comprising a first portion and a retention member, wherein the blister card is fabricated from a paperboard material; anda blister retained on the blister card, the blister comprising a body defining a compartment for retaining the batteries therein, wherein the compartment has a mouth defined by the body, said blister being slidable relative to the blister card between a closed position in which the mouth is substantially covered so that the batteries are inaccessible and an opened position in which the mouth is exposed below the first portion so that at least one battery is accessible for removal through the mouth, wherein the blister further comprises a stop for stopping the blister in the opened position and inhibiting the blister from separating from the first portion of the blister card upon sliding movement of the blister to the opened position;wherein in a first configuration, the retention member is attached to the first portion of the blister card so that the blister is retained on the blister card against slidable movement from the closed position to the opened position;wherein in a second configuration, the retention member is permanently removed from the first portion of the blister card so that the blister is slidable relative to the first portion of the blister card to the opened position; andwherein the blister card includes at least one line of weakness separating the first portion of the blister card and the retention member along which the retention member is tearable away from the first portion of the blister card to permanently remove the retention member from the first portion of the blister card to define the second configuration of the retention member. 2. A blister pack in accordance with claim 1 wherein the line of weakness is other than straight along its entire length. 3. A blister pack in accordance with claim 1 wherein the blister card and the blister are configured relative to each other such that upon removal of the retention member from the first portion of the blister card the at least battery in the blister remains inaccessible in the closed position of the blister. 4. A blister pack in accordance with claim 1 wherein the blister card comprises a first panel and a second panel in opposed relationship with the first panel, the blister being disposed at least in part between the first and second panels without being secured thereto such that the blister is slidable relative to the first and second panels. 5. A blister pack in accordance with claim 4 wherein the second panel has an opening therein, a portion of the blister projecting through said opening in the closed position of the blister. 6. A blister pack in accordance with claim 4 wherein the blister comprises a flange extending transversely outward of the body, the flange being disposed between the first and second panels without being secured thereto. 7. A blister pack in accordance with claim 1 wherein the blister includes a protrusion, the first portion of the blister card engaging the protrusion upon movement of the blister to the opened position to inhibit further movement of the blister beyond the opened position. 8. A blister pack in accordance with claim 1 wherein the blister comprises a first blister defining a first compartment and a second blister retained on the blister card and defining a second compartment for retaining at least one battery therein, said second blister being slidable relative to the blister card and relative to the first blister between a closed position in which the at least one battery is inaccessible and an opened position in which the at least one battery is accessible for removal from the blister pack. 9. A blister pack in accordance with claim 1, wherein the blister card further comprises an opening; wherein the first portion includes a first slot having a first upper end and a first lower end;wherein the first portion includes a second slot having a second upper end and a second lower end;wherein the slots are extensions of the opening;wherein at least a portion of the body extends through the opening,wherein stop comprises a first stop and the blister further comprises a second stop;wherein at least a portion of the first stop is positioned within the first slot for movement between the first upper end and the first lower end;wherein at least a portion of the second stop positioned within the second slot for movement between the second upper end and the second lower end;wherein in the closed position, the stops are located at the upper ends of the slots; andwherein in the opened position, the stops are located at the lower ends of the slots.
