The term of the electric battery, an interconnection of a plurality of similar galvanic cells or elements is referred to, as which initially, e.g. in the voltaic column or Zamboni pile, only non-rechargeable arcogenous “primary cells” or “primary elements” were available. With the development of economically usable rechargeable “accumulators”, also “secondary cells” or “secondary elements”, e.g. As the lead-acid battery around 1850 to 1886, the use of the term “battery” has been extended to the interconnection of several such cells, e.g. in the later starter batteries of motor vehicles or traction batteries of submarines, etc.

From the second half of the 20th century, the use of the term “battery” has also extended to individual primary or secondary cells, the latter being referred to as the “battery cell” or “battery” for short. The described change of linguistic usage was in the DIN standard 40729 accumulators; Galvanic secondary elements; Basic concepts addressed, which under battery “always several connected cells” understood, this term however in the daily routine”distinction has blurred”
