Standard battery nomenclature describes portable dry cell batteries that have physical dimensions and electrical characteristics interchangeable between manufacturers. The long history of disposable dry cells means that many manufacturer-specific and national standards were used to designate sizes, long before international standards were reached.
Under certain conditions, some battery chemistries are at risk of thermal runaway, leading to cell rupture or combustion.As thermal runaway is determined not only by cell chemistry but also cell size, cell design and charge, only the worst-case values are reflected here.
Alkaline batteries are manufactured in standard cylindrical forms interchangeable with zinc–carbon batteries, and in button forms. Several individual cells may be interconnected to form a true "battery", such as the 9-volt PP3-size battery. A cylindrical cell is contained in a drawn stainless steel can, which is the cathode connection.
The F2's interchangeable viewfinders (also known as "heads") [3] marked it as a professional-level SLR and was considered by consumers one of its biggest strengths. By providing updated heads every few years, Nikon was able to introduce new versions of the F2 and keep the basic body in the latest technology until production ended in 1980.

These locks were intended to be interchangeable, being manufactured in large volumes in a steam-powered factory using gauges and lathes. Subsequent experiments have suggested that the lock's components were interchangeable at a higher rate than those of the later British New Land Pattern musket and the American M1816 musket. [8]
