We claim: 1. A dispenser adapted to couple to a fluid container having an opening surrounded by a neck having a vertical axis, the dispenser comprising: a cap adapted to seal the opening fluid tight when the dispenser is coupled to the container; a dispensing head secured to the cap and comprising dispensing elements comprising a fluid pump, a motor adapted to power the pump, a trigger adapted to actuate the motor, a nozzle orifice in fluid communication with a discharge end of the pump, and an energy source chamber containing an energy source, wherein the energy source is isolated from the other dispensing elements by the energy source chamber; and a conduit having a first end in fluid communication with an intake end of the pump and a second end inside the container, wherein a longitudinal axis of the energy source chamber extends laterally from the vertical axis of the neck, and wherein the energy source chamber is positioned generally under the pump and motor. 2. The dispenser of claim 1, wherein the dispensing head is generally pistol-shaped and comprises: a nozzle end comprising the nozzle orifice; a handle; and a rear end; wherein the energy source chamber is positioned adjacent to the rear end of the dispensing head. 3. The dispenser of claim 2, wherein the energy source comprises batteries. 4. The dispenser of claim 3, wherein the dispensing head further comprises a removable cover positioned at the rear end of the dispensing head for accessing the energy source chamber. 5. The dispenser of claim 4, wherein the removable cover completes a portion of an electrical circuit powering the motor. 6. The dispenser of claim 1, wherein the energy source chamber is electrically connected to the motor. 7. The dispenser of claim 5, wherein the energy source chamber further comprises an electrically conductive contact pin protruding from the energy source chamber. 8. The dispenser of claim 7, wherein when the trigger actuates the motor, the trigger is operationally and electrically coupled to the electrically conductive contact pin. 9. A sprayer for dispensing a fluid, the sprayer comprising: a fluid container having an opening surrounded by a neck having a vertical axis; a motor; an actuating mechanism adapted to actuate the motor; a pump driven by the motor and including an intake end and a discharge end; a fluid pathway operably connecting the container, the pump, and a discharge opening of the sprayer; an isolation chamber containing an energy source; and a housing enclosing the motor, the pump, and the isolation chamber, wherein the isolation chamber is positioned generally above the fluid container and the energy source is isolated from the motor and the pump by the isolation chamber, and wherein a longitudinal axis of the isolation chamber extends laterally from the vertical axis of the neck, and wherein the actuating mechanism includes a trigger that engages a switch adjacent the isolation chamber. 10. The sprayer of claim 9, wherein the housing is generally pistol-shaped and comprises: a nozzle end comprising the discharge opening of the sprayer; a handle; and a rear end; wherein the isolation chamber is positioned adjacent to the rear end of the dispensing head. 11. The sprayer of claim 10, wherein the isolation chamber is positioned generally below the pump and motor. 12. The sprayer of claim 9, wherein the housing comprises a removable cover providing access to the isolation chamber. 13. The sprayer of claim 12, wherein the removable cover completes a portion of an electrical circuit powering the motor. 14. The sprayer of claim 9, wherein the isolation chamber is electrically connected to the motor. 15. A dispenser adapted to couple to a fluid container having an opening surrounded by a neck having a vertical axis, the dispenser comprising: a cap adapted to seal the opening fluid tight when the dispenser is coupled to the container; a dispensing head secured to the cap and comprising dispensing elements comprising a fluid pump, a motor adapted to power the pump, a trigger adapted to actuate the motor, a nozzle orifice in fluid communication with a discharge end of the pump, and an energy source chamber containing an energy source, wherein the energy source is isolated from the other dispensing elements by the energy source chamber; a removable cover providing access to the isolation chamber, wherein the removable cover completes a portion of the electrical circuit powering the motor; and a conduit having a first end in fluid communication with an intake end of the pump and a second end inside the container, and wherein a longitudinal axis of the isolation chamber extends laterally from the vertical axis of the neck, and wherein the trigger engages a switch adjacent the isolation chamber. 16. The dispenser of claim 15, wherein the isolation chamber is positioned generally above the neck of the fluid container. 17. The dispenser of claim 16, wherein the energy source comprises two laterally spaced batteries positioned substantially parallel with one another within the isolation chamber.
