The same physically interchangeable cell size or battery size may have widely different characteristics; physical interchangeability is not the sole factor in substituting a battery. [ 1 ] The full battery designation identifies not only the size, shape and terminal layout of the battery but also the chemistry (and therefore the voltage per ...
SR44 and LR44 have a very different discharge curve. A product designed for an SR44 battery will not work well if you substitute an LR44. 71.106.228.229 17:12, 21 March 2010 (UTC) LR44 and SR44 are the same physical size. However, the terminal voltage of the SR version is a tad higher (1.55v -v- 1.5v) and its capacity is also higher.
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.
The total height of the cell is the same as the total distance between terminals. The cell casing is the positive terminal and it is recommended that the outer surface is used for positive connection even though it is possible from the base. No part of the cell is allowed to protrude from the positive terminal surface. E.g. LR44, CR2032
Button, coin, or watch cells. A button cell, watch battery, or coin battery is a small battery made of a single electrochemical cell and shaped as a squat cylinder typically 5 to 25 mm (0.197 to 0.984 in) in diameter and 1 to 6 mm (0.039 to 0.236 in) high – resembling a button.
