These are the common abbreviations for the battery systems. These are the terms that are universally used and you can also find them in this product catalogue. A round battery (see table) is round and flat. A P is the designation for all batteries that are not round. Many chemical abbreviations may therefore be followed by an F (flat) or a P, in addition to an R.
B = Lithium carbon monofluoride (low drain) | BR |
C = Lithium mangaan dioxide (high drain) | CR |
E = Lithium thionyl chloride | ER |
F = Lithium iron disulfide | FR |
G = Lithium Copper oxide | GR |
K = Cadmium | KR |
L = Alkaline | LR |
M = Mercury | MR |
P = Oxygen | PR |
S = Silver | SR |
An LR battery is a round alkaline battery. So a flat alkaline battery would become an LF battery and so on.
