LR41 Equivalent, Voltage, Size, Uses & Life

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 LR41 batteries contain zero percentage mercury(Hg), it is safer in case of battery leaking and very environmentally friendly. These LR41 batteries are also free from cadmium(Cd) and lead(Pb).

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.

LR41 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 LR41 batteries. The LR41 batteries from Murata have achieved excellent leakage resistance by coupling with a special sealing material.

FAQs

What is the difference between LR41 and SR41 batteries?

The nominal voltage of LR41 is 1.5 V whereas the nominal voltage of SR41 is 1.55 V. Thus SR41 provides more power to devices than LR41. The SR41 has a current capacity of 45 mAh, whereas the LR41 has 25-32 mAh capacity.

Is LR41 a lithium battery?

The LR41 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 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.
