Abstract
A battery assembly is provided with two terminals at one end of a stack of cells. One of the terminals is centrally located upon the end of the stack and is electrically connected to the stack at the same end. The other terminal is spaced apart from the central terminal and is electrically connected to the other end of the stack by an elongated conductor. An insulating sheath holds the stack of cells together.
Claims30
A battery assembly, comprising:
- an elongated stack of cells, said stack having a first cell contact at one end and a second cell contact at the other end;
- a holder sheath for holding said stack of cells together and exposing said first and second contacts;
- a first central terminal connected to the first cell contact at said one end and centrally disposed at said one end;
- a first conductive member in contact with said second cell contact;
- a second terminal spaced from said first central terminal at said one end and insulated from said first terminal, said second terminal having an annular collar about the periphery of said one end of the stack;
- and
- an elongated conductive member connecting said first conductive member with said second terminal, whereby positive and negative connection to said battery assembly is provided through said first and second terminals at said one end of said battery assembly.

A battery assembly, comprising:
- an elongated stack of cells, said stack having a first cell contact at one end and a second cell contact at the other end;
- a holder sheath for holding said stack of cells together and exposing said first and second contacts, the holder sheath surrounding the cells and extending from the one end to the other end;
- a first terminal connected to the first cell contact at said one end;
- a first conductive member in contact with said second cell contact;
- a second terminal adjacent to said first terminal at said one end and insulated from said first terminal;
- an elongated conductive member extending along the outside of the holder sheath, and connecting said first conductive member with said second terminal, whereby positive and negative connection to said battery assembly is provided through said first and second terminals at said one end of said battery assembly for charging and discharging the battery assembly;
- and
- an outer sheath extending around the holder sheath with the elongated conductive member being between the holder sheath and the outer sheath.

A battery assembly, comprising:
- an elongated stack of cells, said stack having an annular shoulder and a first cell contact at one end, and a second cell contact at the other end;
- an insulating holder sheath for holding said stack of cells together, said holder sheath having an end portion partially covering said one end of the stack, and a cylindrical portion extending along the stack from said one end to said other end, and exposing said first and second contacts;
- a conductive member extending along the exterior of the cylindrical portion of said insulating sheath from one end of said stack to the other, and connected with said second cell contact;
- and
- a pair of terminals at said one end for charging and discharging said cells, said terminals comprising:
- a first central terminal connected to the first cell contact at said one end and centrally disposed at said one end;
- and
- a second terminal overlying said end portion of said insulating holder sheath and spaced from said first central terminal at said one end of the stack, said second terminal connected to the conductive member.
5 more elements
A battery assembly for providing electrical power within a flashlight having a pair of concentric springs extending rearwardly from a head assembly thereof for charging and for discharging said battery assembly, the battery assembly comprising:
- a stack of rechargeable cells, said stack having a first cell contact at one end of the stack and a second cell contact at the other end of the stack;
- an insulating sheath for holding the stack of cells together and exposing the first and second cell contacts;
- a central terminal connected to the first cell contact and centrally disposed at the one end of the stack, said central terminal having a terminal surface for connecting with the innermost of the concentric springs;
- an outer terminal substantially surrounding the first central terminal and insulated therefrom for connecting with the outermost of the concentric springs;
- and
- a conductive member extending along the exterior of the insulating sheath, said conductive member connected between the outer terminal and the second cell contact for conducting electrical current in one direction between the outer terminal and the second cell contact during charging, and for conducting electrical current in the opposite direction between the outer terminal and the second cell contact during discharging.
