Abstract

The invention is a battery with power output terminals on opposite ends of a battery and a power output terminal on the side wall of the battery that has the same polarity as one of the end power output terminals. The presence of the side terminal is indicative of a battery characteristic and allow a battery operated device requiring that characteristic to selectively use the battery when designed to use the side terminal and opposite polarity end terminal to provide energy to operate the device. Because the battery also has opposite polarity end terminals, the battery can be used in devices designed to use batteries of the same dimensions and having the same nominal voltage. The location of the side terminal can also be indicative of additional battery characteristics, allowing the selective use of batteries in devices based on various device requirements.

Claims

1. A rechargeable battery comprising at least one rechargeable electrochemical cell and at least three power output terminals, wherein:

the battery has a first end, a second end, a side wall disposed between the first and second ends, a height, and a width that is smaller than the height;

an electrically nonconductive covering is disposed on at least a portion of the side wall of the battery and on a peripheral portion of the first end;

a first end power output terminal having a polarity is disposed on the first end of the battery and comprises a longitudinal projection beyond the battery side wall;

a second end power output terminal having a polarity opposite that of the first end terminal is disposed on the second end of the battery, the second end terminal optionally having a longitudinal projection beyond the battery side wall, the optional projection having a minimum width beyond the side wall that is larger than a minimum width of the first end terminal projection beyond the side wall; and

an exposed, recessed first side power output terminal having a polarity the same as that of the second end terminal is disposed on the side wall of the battery;

wherein a portion of the first side terminal is disposed equidistant between longitudinally distal edges of the battery side wall.

2. The battery as defined in claim 1, wherein the first side terminal comprises a continuous band around a battery perimeter.

3. The battery as defined in claim 1, wherein the first side terminal is offset from a point midway between uppermost and lowermost edges of the battery side wall.

4. The battery as defined in claim 3, wherein the first side terminal is offset toward the second end, and no nonconductive covering is present between the second end and side terminals.

5. The battery as defined in claim 1, wherein the first side terminal is a sole side terminal.

6. The battery as defined in claim 1, wherein the battery has a second side power output terminal having the same polarity as the first side terminal disposed on the side wall of the battery and separated from the first side terminal by a portion of the nonconductive covering, the side wall has a first longitudinally distal edge in proximity to the first end of the battery and a second longitudinally distal edge in proximity to the second end of the battery, and a longitudinal distance from the first distal edge to the first side terminal is equal to a longitudinal distance from the second distal edge to the second side terminal.

7. The battery as defined in claim 1, wherein each cell in the battery has a nominal voltage of 1.2 to 1.5 volts.

8. The battery as defined in claim 7, wherein the battery has a nominal voltage of 1.2 to 1.5 volts.
