What are LR41 Equivalent and Applications

Last updated on April 3rd, 2024 at 04:14 pm

LR41 battery is a popular type of alkaline button cell battery. It is a non-rechargeable battery that is designed to be remarkably similar to silver oxide coin-based batteries. It gives 1.5 V output, has a typical capacity of up to 35 mAh capacity, and is 7.9 mm in diameter and 3.6 mm in height. 

Since the battery contains zero percentage mercury(Hg), it is safer in case of battery leaking and very environmentally friendly. These batteries are also free from cadmium(Cd) and lead(Pb).

LR41 exact equivalents are(same dimensions and voltage) SR41, L736F G3, LR4192, LR736, A63 , SR41SW, 325 and 384. For more read below.

The standard shelf life of an LR41 battery varies from 2 years to 5 years. It highly depends on its storage temperature.

What does LR41 stand for?

According to the battery nomenclature, the first two English alphabets represent battery type and shape respectively. In LR41 batteries “L” represents it is alkaline and “R” represents its round shape.

As for the 41, LR736 is the original name for LR41, where 7 represents its diameter and 3.6 represents its height.

these are alkaline manganese batteries. The manganese oxide is used as cathode material, making it cost-effective. Most renowned manufacturers like Toshiba, Maxell, Murata, and many more manufacture these coin cells. These batteries from Murata have achieved excellent leakage resistance by coupling with a special sealing material.

What is the difference between LR41 and SR41 batteries?

SR41 batteries deliver more power than LR41 batteries. SR41 also has a higher current capacity of 45 mAh compared to LR41, which typically ranges from 25-32 mAh.

Is LR41 a lithium battery?

It is not a lithium battery, but an alkaline battery. The LR41 battery is usually confused with a lithium battery due to the letter L. But The nomenclature is based on the IEC 60086-3 standard in which the first letter stands for the battery chemistry. Accordingly, L stands for alkaline chemistry.

Are LR41 and 312 batteries interchangeable?

The 312 battery has a slightly lower voltage of 1.40-1.45 volts, but it has a much bigger capacity, usually around 160 mAh.
