An improved hand-held data terminal is provided. A sensing circuit senses the presence of rechargeable batteries. A rechargeable battery pack can be used in the hand-held data terminal. The battery pack can include a short circuit element. The short circuit element comes into contact with the hand-held data terminal when the rechargeable battery pack is assembled with the hand-held data terminal. The short circuit element, when in contact with the hand-held data terminal, serves to indicate the presence of the rechargeable battery pack and to thereby enable the recharging capabilities of the hand-held data terminal. A battery pack which does not contain the short circuit element cannot be recharged by the hand-held data terminal since the recharging circuit of the data terminal would remain in a disabled state. Further, the battery pack can be shaped asymmetrically so that it can only be assembled with the hand-held data terminal in an operational orientation.
