What is an lr44 battery

The LR44 Battery is a small button cell battery of alkaline composition，due to its convenient and small size characteristics, so it is often used in our common small electronic devices, is also a common battery, its most common brands are such as Murata, Panasonic, Toshiba and so on. Battery is an important way for us to store energy and obtain energy. Without battery, we may not be able to obtain such a convenient life experience, so the existence of batteries is very important to the quality of life of human beings.

lr44 battery equivalent 

LR44, also known as one of the button batteries commonly used in electronic devices like A76, AG 13, L1154 and so on. This battery provides stable power support for the device with a voltage of 1.5V.

What battery is equivalent to lr44

Among the alkaline battery with a voltage of 1.5v, there are many models with more similar functions to Lr 44, such as battery 13, A76,157,303,357 and SR 44. Although they are similar, but they still have some differences, users need to make choices according to their own needs, we provide some of the application scope of these products to provide reference:  

In principle, the above batteries can be universal, but because there are still some gaps in function, it is better to consider its compatibility in the choice of use.

What are lr44 batteries used for

The R44 is a very popular battery, ideal for applications that require small but stable batteries, giving it a wide range of applications, in addition to some of the applications mentioned above, and some products are still widely used in the LR44.   

Although the application of LR44 is very wide, it is necessary to pay attention when purchasing and using LR44 batteries, brand, quality, price, power, production date and other factors. Otherwise, it will also affect the stability of their own products.

What size are lr44 batteries

The battery is much smaller than the AA battery，The diameter of LR44 is about 11.6mm, and the thickness is about 5.4mm.

Are lr44 batteries the same as 357

The LR44 is similar to the 357 and has similar uses, but there are still some gaps that need to be distinguished. Generally speaking, the overall function of 357 is better than LR44. What exactly is better? I can elaborate on that.

Many shopping platforms list LR44 and 357 as replaceable products, but 357 has a relatively longer life and a relatively higher power, with LR44 being 1.5 volts and 357 being 1.55volts. The main reason why the voltage is slightly higher than that of LR44 is that 357 is a silver oxide battery, while LR44 is an alkaline battery, so 357 is more suitable for products with higher energy requirements, and it performs better above precision. Although LR44 is slightly inferior in life span and power, LR44 is more stable near the end of its life cycle. They are always relatively 11.6MM*5.4MM to some extent the size is interchangeable. In addition, there are also some differences in the operation temperature. The operation temperature of LR44 is-20-54 degrees Celsius, while 357 is 0-50 degrees Celsius. LR44 also has certain advantages, it has a higher leakage resistance, that is, better sealing.

lr44 battery life

Generally speaking, the shelf life of LR44 alkaline battery is within 2-5 years, so when buying, you need to pay attention to whether its production date exceeds this time, so its service life needs to be determined according to different equipment, and the equipment with higher energy consumption will greatly reduce its life. In the process of using at the same time, it should be attention to charging, incineration and disassembly.

lr44 battery replacement 

What battery replaces a lr44 ? LR44 / AG 13 / A76 / L1154 / 357A these batteries are nominally replaceable batteries, and most of the sales platform also uses these batteries as general treatment. But the practical application scenario in the battery still exist some subtle gap, need according to different products to match, silver oxide battery in theory can replace LR44, but before replacing and replacement battery, should check the type of battery, measurement, capacity, maximum voltage current and chemical composition, whether to meet your equipment requirements is compatible.   

lr44 battery positive side

How to check the positive and negative electrodes of the button battery? Most of the button buttons are easy to identify, because they will be marked by + -number, most of them have + number for positive electrode and-for negative electrode.   

How the lr44 works

LR44 battery:silver oxide battery, the battery by silver oxide as the positive electrode, metal zinc powder as the negative electrode,The positive and negative ends of LR44 are made of silver oxide and manganese dioxide. Due to the characteristics of these materials, when the current flows from the positive end like the negative end, silver oxide reacts with manganese dioxide, and manganese dioxide will decompose into manganese oxide, thus producing electrons.When the battery is working, the zinc reacts with the hydroxide ion (OH) in the electrolyte solution to produce zinc hydroxide (Zn (OH) ₂), which also releases electrons. Through the electricity generated by this reaction, the LR44 battery can provide electronic support suitable for most electronic devices.
