AG13/LR44/SR44/SR44SW/357 Battery Chemistries Comparison ChartĬomparison and examples of the button/coin 11.6 x 5.4 mm cell batteries are given in the following table.
#LR44 BATTERIES CODE#
if the battery code after the digits contains 'W', then the battery complies with the IEC 60086-3 watch batteries standard. if the battery code after the digits doesn't contain 'P' or 'S', then most probably that battery contains an organic electrolyte. if the battery code after the digits contains 'S', then it is the battery with sodium hydroxide electrolyte. if the battery code after the digits contains 'P', then it is the battery with potassium hydroxide electrolyte. However, due to the presence of mercury, these batteries are no longer in use. if the battery code starts with the 'M' or 'N', then it is a mercury-oxide coin cell. if the battery code starts with the 'P', then it is a zinc-air coin cell.
if the battery code starts with the 'S', then it is a silver oxide coin cell. if the battery code starts with the 'L', then it is most probably an alkaline coin cell. However, sometimes manufacturers mark silver-oxide batteries with both SG13 (correct) and AG13 (not so correct) to emphasize that their battery is a replacement for AG13/LR44/LR1154 battery. AG13 vs SG13: AG13 should be 'alkaline G13,' and SG13 should be 'silver-oxide G13' battery. Their capacity depends on the used chemistry but also on the cut-off voltage of the used device. LR44/LR1154 (alkaline) or SR44/SR1154 (silver-oxide) batteries are button/coin cell batteries 11.6 mm in diameter and 5.4 mm in height. LR44/SR44 Battery Features and Specifications
