LR41 vs AG3: Are They Interchangeable?
LR41 and AG3 (also 392 = SR41) are interchangeable 7.9mm x 3.6mm, 1.5V alkaline cells. They are the same battery under different names — pick either to replace a watch or small sensor.
What are the LR41 battery characteristics?
These are the LR41 performance figures we declare under EU Regulation 2023/1542: rated capacity and the maximum available duration under a standard continuous load. Real discharge performance depends on load, temperature and cut-off voltage, so the exact test conditions are stated underneath the table.

What batteries are equivalent to the LR41?
The LR41 is interchangeable with any cell of the same diameter, thickness and voltage, so an equivalent can be substituted without changing the device. Buyers look these cells up under three numbering systems at once — IEC, ANSI and manufacturer codes — and the list below covers the names the LR41 is sold under.
Look any number up in the cross-reference tool → — type the marking on your cell and see where it lands, or pick your device and see the cells we supply for it.

Where is the LR41 battery used?
The LR41 is used in watches, thermometers, glucose meters and other compact devices that draw small currents over long periods. Its 1.5V output and 34mAh capacity suit equipment that has to run for months without a battery change. The blocks below set out what to check for each device type.
LR41 Watch Battery
The LR41 is a common watch battery cell. Match the model number on your old cell (LR41 = AG3 = L736 = V3GA) to the one you replace it with — same size and voltage means an easy swap.
What do buyers ask about the LR41 battery?
