Q:

What is the equivalent of the L1154 battery?

A:

A L1154 battery is a 1.5-volt alkaline button cell battery of the LR44 specification. Various manufacturers call this battery by different names, making it difficult to find an exact replacement without looking at a comparison chart. Some equivalents are: 1128MP, 1166A, AG13, D76A, G13A, GPA7, GPA76, LR44, LR1154 and L1154.

In the LR44 battery type, the letter L denotes that the electrochemical system uses a zinc negative electrode, a manganese dioxide depolarizer and a positive electrode with an alkaline electrolyte. The R44 indicates a round cell 11.4 ± 0.2 millimeters in diameter and 5.2 ± 0.2 millimeters in height, as defined by IEC standard 60086. A SR44 battery is similar to an L1154 but uses silver oxide as the electrolyte and provides more electrical capacity.
