battery (redirected from stamp battery)

battery, in criminal and tort law, the unpermitted touching of any part of the person of another, or of anything worn, carried by, or intimately associated at that moment (as a chair being sat on) with another. Contact must be intended by the aggressor, must be reasonably considered offensive, and must be without consent by the one affected. (Consent is assumed for the ordinary and customary contacts of everyday life.) Gross negligence may provide the intent necessary to constitute a battery. Actual physical injuries need not be sustained by the victim; thus a doctor who performs an operation without consent can be sued for battery, even though the patient is benefited by the operation. The term "assault and battery" refers to a crime, the unlawful touching of another as the consummation of an assault.

Any of a class of devices, consisting of a group of electrochemical cells (see electrochemistry), that convert chemical energy into electrical energy; the term is also commonly applied to a single cell of this kind. A wet cell (e.g., a car battery) contains free liquid electrolyte; in a dry cell (e.g., a flashlight battery) the electrolyte is held in an absorbent material. Chemicals are arranged so that electrons released from the battery's negative electrode flow (see electric current) through a circuit outside the battery (in the device powered by it) to the battery's positive electrode. The battery's voltage depends on the chemicals used and the number of cells (in series); the current depends on the resistance in the total circuit (including the battery—and thus on electrode size). Multiple batteries may be connected in series (the positive electrode of one to the negative electrode of the next), which increases total voltage, or in parallel (positive to positive and negative to negative), which increases total current. Batteries that are not rechargeable include standard dry cells used in flashlights and certain wet cells for marine, mine, highway, and military use. Car batteries, many kinds of dry cells used in cordless appliances, and batteries for certain military and aerospace uses may be recharged repeatedly.
