6. The system of claim 5 further comprising an electrically conductive cable which is electrically coupled with the post, and wherein the cable and extension member extend outwardly from the post in opposite directions which are substantially perpendicular to the post.

7. The system of claim 1 wherein the sleeve and post have a circular cross-section and the electrically insulative members of the receptacle and insertion connection member are annular rings.

8. The system of claim 7 wherein a diameter of the electrically insulative member of the insertion connection member is larger than a diameter of the electrically insulative member of the receptacle connection member.

9. The system of claim 1 wherein the insertion connection member comprises an extension member which extends outwardly in a substantially perpendicular direction from the post.

10. The system of claim 9 wherein the extension member provides a grippable member having a surface which is substantially perpendicular to the post and which may be gripped by a user to assist with detachment of the insertion connection member from the receptacle connection member.

11. The system of claim 1 wherein the insertion connection member comprises an extension member which extends outwardly from the post a distance which is approximately the same as the length of the electrically conductive post.

12. The system of claim 1 wherein the insertion connection member comprises an electrical conductor which is coupled with the post, and wherein the post is substantially perpendicular to at least a portion of the electrical conductor which is adjacent to the post.

13. An electrical apparatus comprising:

an electrically insulative housing;

electrical circuitry within an interior of the housing; and

at least one terminal comprising a receptacle connection member which is electrically coupled with the electrical circuitry within the interior of the housing, and wherein the receptacle connection member comprises an electrically conductive sleeve which defines a terminal opening and which is configured to receive and electrically couple with an insertion connection member; and

wherein the receptacle connection member comprises an electrically insulative member which forms a seal with an electrically insulative member of the insertion connection member to insulate the receptacle and insertion connection members from an environment outside of the housing when the receptacle and insertion connection members are electrically coupled with one another.

14. The apparatus of claim 13 further comprising the insertion connection member which comprises an electrically conductive post which is configured to be received within the sleeve.

15. The apparatus of claim 14 wherein the housing comprises a planar surface and the insertion connection member comprises an extension member, and wherein the post is substantially perpendicular to the planar surface and the extension member is substantially parallel to the planar surface when the post is received within the sleeve.

16. The apparatus of claim 13 wherein a portion of the sleeve extends outwardly of the housing and the electrically insulative member of the receptacle connection member is provided about the outwardly extending portion of the sleeve.

17. The apparatus of claim 13 wherein an exterior surface of the electrically insulative member of the receptacle connection member comprises a circumferential groove.

18. The apparatus of claim 17 further comprising a sealing gasket within the groove and which is configured to contact an interior surface of the electrically insulative member of the insertion connection member.

19. The apparatus of claim 13 wherein the sleeve and post have a circular cross-section and the electrically insulative members of the receptacle and insertion connection member are annular rings.

20. The apparatus of claim 19 wherein a diameter of the electrically insulative member of the insertion connection member is larger than a diameter of the electrically insulative member of the receptacle connection member.

21. The apparatus of claim 13 wherein the electrical apparatus is a battery and the electrical circuitry comprises at least one electrochemical cell which is electrically coupled with a plurality of the terminals.

22. An electrical connection member comprising:

an electrically conductive lug;

an electrically conductive post which is electrically coupled with and substantially perpendicular to the lug and configured to be electrically coupled with an electrically conductive sleeve of another electrical connection member when the post is inserted into the sleeve; and

an electrically insulative member about the electrically conductive post and configured to form a seal with an electrically insulative member of the another electrical connection member when the post is inserted into the sleeve.

23. The member of claim 22 wherein the insertion connection member comprises an extension member which extends outwardly from the post.

24. The member of claim 23 further comprising an electrically conductive cable which is electrically coupled with the post, and wherein the cable and extension member extend outwardly from the post in opposite directions which are substantially perpendicular to the post.

25. The member of claim 24 wherein the extension member provides a grippable member which may be gripped by a user to assist with detachment of the insertion connection member from the receptacle connection member.
