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.

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
