Abstract

A battery cell stick (100) is formed by vertically-stacking bare rechargeable cylindrical battery cells (110, 120) and then wrapping the cells in a common label (130) having an adhesive backing (132). Subsequently, multiple cell sticks (100, 150) are combined in a single plastic housing (160). The assembly is wrapped with an additional adhesive-backed label (180). Positively- and negatively-polarized terminal ends (112, 152) are exposed through openings (172, 174) in the housing.

Claims

1. A battery assembly, comprising:

first and second sets of cylindrical battery cells, each battery cell having a positively-polarized terminal end, an opposing negatively-polarized terminal end and a peripheral portion;

first and second adhesive-backed labels; and

a plastic housing,

said first set of battery cells disposed end-to-end, the first adhesive-backed label wrapped around a peripheral portion of each of the first set of battery cells to form a first cell stick,

said second set of battery cells disposed end-to-end, the second adhesive-backed label wrapped around a peripheral portion of each of the second set of battery cells to form a second cell stick, and

the first and second cell sticks attached to said plastic housing; and

also comprising

a third adhesive-backed label wrapped around the entire assembly.

2. A two-way radio having a rechargeable battery package, the battery package comprising:

a first battery cell stick, including;

upper and lower cylindrical battery cells disposed end to end such that a negatively-polarized terminal portion of the upper cell is in direct and intimate contact with a positively-polarized terminal portion of the lower cell, and a first adhesive-backed label wrapped around a peripheral portion of both cells;

a second battery cell stick, including;

upper and lower cylindrical battery cells disposed end to end such that a positively-polarized terminal portion of the upper cell is in direct and intimate contact with a negatively-polarized terminal portion of the lower cell, and a second adhesive-backed label wrapped around a peripheral portion of both cells;

a plastic battery housing, including;

a top, a bottom, and first and second receiving portions, the top having first and second apertures positioned above the corresponding first and second receiving portions; and

a third adhesive-backed label, wherein

the first and second battery cell sticks are disposed within the corresponding first and second housing receiving portions, the positively-polarized end of the first cell stick upper cell exposed through the first aperture, the negatively-polarized end of the second cell stick upper cell exposed through the second aperture, and the third adhesive-backed label wrapped around the cell sticks and the housing.
