primary cell[′prī‚mer·ē ′sel]
A cell that delivers electric current as a result of an electrochemical reaction that is not efficiently reversible, so that the cell cannot be recharged efficiently.
A cell that generates electric current by electrochemical means; the discharge of electric current causes one of the electrodes in the cell to be consumed; usually a cell cannot be recharged from an external source of electric power, although some can be recharged to a limited extent.
