A primary battery or primary cell is a battery (a galvanic cell) that is designed to be used once and discarded, and it is not rechargeable unlike a secondary cell (rechargeable battery). In general, the electrochemical reaction occurring in the cell is not reversible, rendering the cell unrechargeable.
From top to bottom: a large 4.5-volt 3R12 battery, a D Cell, a C cell, an AA cell, an AAA cell, an AAAA cell, an A23 battery, a 9-volt PP3 battery, and a pair of button cells (CR2032 and LR44) Batteries are classified into primary and secondary forms: Primary batteries are designed to be used until exhausted of energy then discarded. Their ...
Some such circuits increase cell diameter instead. The increased dimensions may mean the cell will no longer fit in battery compartments intended for cells without such circuitry. Commonly-used designation numbers indicate the physical dimensions of the cylindrical cell, as given in IEC standard 60086-1 for cylindrical primary cells.
A Duracell AA size alkaline cell, one of the many types of battery. This list is a summary of notable electric battery types composed of one or more electrochemical cells. Three lists are provided in the table. The primary (non-rechargeable) and secondary (rechargeable) cell lists are lists of battery chemistry.
Primary cells are made in a range of standard sizes to power small household appliances such as flashlights and portable radios. [citation needed] As chemical reactions proceed in a primary cell, the battery uses up the chemicals that generate the power; when they are gone, the battery stops producing electricity. [citation needed]
The blaze ripped through a factory run by primary battery manufacturer Aricell in Hwaseong, an industrial cluster southwest of the capital Seoul. ... (0131 GMT) after a series of battery cells ...
Wet cells were used commercially in the telegraph and telephone systems. Early electric cars used semi-sealed wet cells. One important classification for batteries is by their life cycle. "Primary" batteries can produce current as soon as assembled, but once the active elements are consumed, they cannot be electrically recharged.
