A battery assembly comprises a battery and a housing adapted for use in an environment often exposed to water. The housing preferably has recessed portions spaced far apart at the top end thereof, with electrical terminals disposed in the recessed portions. The recessed portions are configured to securely receive corresponding downward-facing compartments disposed at the top of the battery, wherein the compartments have recessed openings housing electrical terminals. Accordingly, the electrical terminals of the housing are configured to contact the electrical terminals of the battery when the battery's compartments are disposed in the housing's recessed portions, forming a substantially watertight seal.

What is claimed is: 1. A battery assembly, comprising: a battery having a body with a base and opposite side faces extending upwardly therefrom, a compartment connected to one side face and a second compartment connected to the opposite side face, each compartment defining a downward-facing cavity,

What is claimed is: 1. A battery assembly, comprising: a battery having a body with a base and opposite side faces extending upwardly therefrom, a compartment connected to one side face and a second compartment connected to the opposite side face, each compartment defining a downward-facing cavity, each cavity housing an electrical terminal therein facing toward the base of the battery, each compartment including overhanging skirts disposed about the electrical terminals, the skirts substantially surrounding the electrical terminals; and a housing having opposite side walls extending from a base to free ends of the side walls, each of the opposite side walls defining an upward-facing recessed portion, each recessed portion housing an electrical terminal facing away from the base of the housing, wherein the recessed portions are configured to removably receive the compartments therein so that the electrical terminals of the battery operatively contact the electrical terminals of the housing. 2. The battery assembly of claim 1, wherein the compartments are offset relative to a longitudinal plane extending across a midline of the body, said offset defining a first distance between the compartments and a front face of the battery, and a second distance between the compartments and a back face of the battery, wherein the second distance is shorter than the first distance. 3. The battery assembly of claim 2, wherein the recessed portions are disposed a third distance from a rear wall of the housing, the third distance generally equal to the second distance. 4. A method for installing a battery, comprising: providing a battery with opposite side faces, with one battery electrode disposed on one side face and a second battery electrode disposed on the opposite side face, wherein the battery comprises compartments that house the battery electrodes, wherein the battery further comprises overhanging skirts extending about the compartments; providing a housing with opposite side walls, with one housing electrode disposed on one side wall and a second housing electrode disposed on the opposite side wall, wherein the housing comprises recessed portions that house the housing electrodes; moving the battery and housing relative to each other so that the battery electrodes and housing electrodes operatively contact each other; and moving the battery and housing relative to each other so that the skirts extend about the recessed portions. 5. The method of claim 4, wherein the battery electrodes face in a direction toward a base of the battery. 6. The method of claim 4, wherein the housing electrodes face in a direction away from a base of the housing. 7. The method of claim 4, wherein the battery terminals have the same sign. 8. The method of claim 4, wherein the housing terminals have the same sign. 9. The method of claim 4, wherein the battery electrodes are disposed proximal to a portion of the battery that is configured to be distal to the housing after the moving steps. 10. A battery assembly comprising: a battery having battery electrodes disposed on opposite sides of the battery; a housing having housing electrodes disposed on opposite side walls of the housing, wherein the housing is configured to removably receive the battery therein so that the housing electrodes operatively contact the battery electrodes; and overhanging skirts disposed about the battery electrodes, wherein the skirts substantially surround the housing electrodes when the battery is disposed in the housing. 11. The battery assembly of claim 10, wherein the battery has a base configured to be inserted into the housing and a top opposite to the base, wherein the battery electrodes are disposed proximal the top of the battery. 12. The battery assembly of claim 10, wherein the battery electrodes face towards a base of the battery. 13. The battery assembly of claim 10, wherein the battery electrodes have the same sign. 14. The battery assembly of claim 1, wherein the skirts provide a labyrinth seal around the electrical terminals. 15. The battery assembly of claim 1, wherein the compartments of the battery are disposed proximal to a portion of the battery that is distal to the housing and are configured to fit into the recessed portions of the housing. 16. The battery assembly of claim 1, wherein the electrical terminals of the battery have the same sign. 17. The battery assembly of claim 1, wherein the electrical terminals of the housing have the same sign. 18. The method of claim 4, wherein, after moving the battery and housing relative to each other so that the skirts extend about the recessed portions, the skirts providing a labyrinth seal around the battery electrodes. 19. The method of claim 4, wherein, after moving the battery and housing relative to each other so that the battery electrodes and housing electrodes operatively contact each other, the skirts substantially surround the housing electrodes. 20. The battery assembly of claim 10, wherein the housing electrodes face away from a base of the housing. 21. The battery assembly of claim 10, wherein the housing electrodes have the same sign. 22. The battery assembly of claim 10, wherein the skirts provide a labyrinth seal around the battery electrodes.
