A battery includes a plurality of stacking supports including retaining flanges and support surfaces; and a plurality of generally cylindrical cells. Each cell is supported on a pair of the support surfaces. Each cell has an annular notch defined in a side wall with the annular notch mating with one retaining flange. The cells are arranged upon the stacking supports in a plurality of cell rows. The support surfaces are arranged on the stacking supports in such a manner so that the cells are arranged in a close-packed array and to maintain at least a predetermined distance between adjacent cells.

The battery of claim 1 wherein stacking supports separate each cell row. 3. The battery of claim 1 wherein the plurality of cell rows comprises at least a first row of cells and a second row of cells, the first row of cells is supported on a pair of stacking supports, and the first row of cells is placed in the pair of stacking supports in an alternating fashion with a positive terminal of each first row cell adjacent to a negative terminal of another first row cell. 4. The battery of claim 1, further comprising: busbars electrically coupling a positive terminal of one cell with a negative terminal of a cell adjacent to the one cell. 5. The battery of claim 3 wherein the annular notch is adjacent the positive terminal of each cell and each stacking support has one retaining flange for every other pair of support surfaces. 6. The battery of claim 1 wherein the predetermined distance is based on preventing electrical shorting between adjacent cells. 7. A battery, comprising: a first plurality of cell pairs, each cell pair coupled longitudinally and each cell of the cell pair having an annular notch proximate a positive terminal of the cell;first and second lower support strips having:a side having support surfaces to receive the first plurality of cell pairs; anda retaining flange extending upwardly from the side and mating with one notch of one cell pair. 8. The battery of claim 7 wherein the first and second lower support strips are roughly rectangular cuboid in shape with long edges of the lower support strips arranged parallel to each other and a longitudinal axis of cell pairs arranged substantially perpendicular to the long edges of the lower support strips. 9. The battery of claim 7, further comprising: first and second middle support strips placed over the first plurality of cell pairs wherein lower sides of the middle support strips have support surfaces and at least one retaining flange extending downwardly, the support surfaces engage with the first plurality of cell pairs, and the downwardly extending retainingflanges mate with notches associated with cell pairs. 10. The battery of claim 9, wherein upper sides of the first and second middle support strips have support surfaces configured to receive cell pairs and upwardly extending retaining flanges, the battery further comprising: a second plurality of cell pairs with each cell pair coupled longitudinally and each cell having an annular notch proximate a positive terminal wherein annular notches mate with the upwardly extending retaining flanges associated with first and second middle support strips. 11. The battery of claim 10, further comprising: third and fourth middle support strips placed over the second plurality of cell pairs wherein lower sides of the middle support strips have support surfaces and at least one retaining flange extending downwardly, the support surfaces engage with the second plurality of cell pairs, the downwardly extending retaining flanges mates with notches associated with cell pairs, and upper sides of the third and fourth middle support strips have support surfaces configured to receive cell pairs and an upwardly extending retaining flange; anda third plurality of cell pairs with each cell pair coupled longitudinally and each cell having an annular notch proximate a positive terminal wherein annular notches mate with the upwardly extending retaining flanges associated with third and fourth middle support strips. 12. The battery of claim 11, further comprising: first and second upper support strips placed over the third plurality of cell pairs wherein a lower side of the upper support strips has support surfaces and at least one retaining flange extending downwardly wherein the support surfaces engage with the third plurality of cell pairs and the downwardly extending retaining flange mates with one annular notch associated with one cell pair. 13. The battery of claim 12, wherein: the first and second lower strips are first and second lower end strips;the first and second upper strips are first and second upper end strips; andthe first, second, third, and fourth middle strips are first, second, third, and fourth middle end strips, the battery further comprising: a lower center strip having support surfaces to receive the first plurality of cell pairs;a first center strip having support surfaces on an lower and upper side of the first center strip to engage with the first plurality of cell pairs and to receive the second plurality of cell pairs, respectively;a second center strip having support surfaces on an lower and upper side of the second center strip to engage with the second plurality of cell pairs and to receive the third plurality of cell pairs, respectively; andan upper center strip having support surfaces to engage cell pairs wherein the support surfaces of the lower center strip, the first center strip, the second center strip, and the upper center strip contact the cell pairs proximate a location where cells are joined to form cell pairs. 14. The battery of claim 7 wherein each cell pair has a positive terminal end and a negative terminal end and the first plurality of cell pairs are placed in the first lower support strip in an alternating pattern such that every other set of support surfaces receives a positive terminal end, the remaining support surfaces receive a negative terminal, the cells are roughly cylindrical, and the receiving support surfaces contact the cells at approximately five and seven o'clock positions and the engaging support surfaces contact the cells at approximately eleven and one o'clock positions. 15. A method to assemble a battery, comprising: placing a plurality of lower support strips on a surface;placing a first plurality of generally cylindrical cells onto support surfaces of the lower support strips wherein the cells are arranged substantially parallel and placed in an alternating fashion with every other cell having a negative terminal pointing in a first direction and the remaining cells having a positive terminal pointing in the first direction;wherein the lower support strips have retaining flanges proximate every other pair of support surfaces and the cells have an annular notch proximate a positive terminal end of the cell; andengaging the annular notches with the retaining flanges concomitantly with the placing of the first plurality of cells onto the support surfaces of the lower support strips. 16. The method of claim 15, further comprising: placing middle support strips over the first plurality of cells;placing a second plurality of generally cylindrical cells onto the middle support strips wherein the middle support strips have a first set of support surfaces on a first side of the middle support strips placed onto the first plurality of cells and a second set of support surfaces on a side of the middle support strips opposite the first side with the first set of support surfaces and the second set of support surfaces arranged so that the first plurality of cells and the second plurality of cells are in a close-packed array. 17.
