The L1154F battery, also called LR44, AG13, or A76, is a small button cell used in many everyday devices. It provides 1.5 volts of power and is known for being reliable, affordable, and easy to replace. This article explains its features, common uses, safe handling, and how to choose the right replacement.
L1154F Overview
The designation L1154F is simply another trade label for the commonly known LR44 alkaline button cell, meaning it refers to the same physical size and chemistry rather than a unique battery type. Industry standards identify this cell under multiple codes: the IEC name is LR44, the ANSI/NEDA code is 1166A, and it has a nominal voltage of 1.5 V. Its chemistry is alkaline zinc–manganese dioxide, making it reliable for stable discharge in small devices. Because of these multiple naming conventions, customers often see labels like AG13, A76, 357, or L1154F, but all of them point to the same interchangeable cell size. This standardization makes purchasing simpler, but it also means that buyers need to carefully match specifications instead of relying solely on the label.

L1154F Dimensions and Polarity
It is a small cylindrical battery with a diameter of 11.6 mm and a height of 5.4 mm, making it compact for use in small electronic devices. The diagram also highlights polarity: the flat top side marked with a “+” is the positive terminal, while the opposite flat side serves as the negative terminal.
Chemistry and Discharge Behavior
The performance of a button cell is largely determined by its chemistry, and for this size, two main types are commonly used. One of the most widespread is the alkaline variant, labeled under codes such as L1154F, LR44, AG13, or A76. These cells have a nominal voltage of 1.5 V and are characterized by a discharge curve that slopes gradually downward, meaning the voltage steadily decreases as the battery is consumed.
