Everything uses the LR44 battery or LR44 battery alternatives, from medical devices to children’s toys. They power everything and daily make our lives possible.
But how well do you know them? Let’s examine the details and contrast them with some other batteries available on the market.
Technical Features And Specifications Of The LR44 Battery
Based on the initials “LR,” the designation “LR44” was created. According to the IEC name declaration, the letter “L” denotes that the cell is an alkali-manganese cell. The “R” represents “round cell.” and the number 44 is a part of the name.
The LR44 is a coin battery. It is a popular button cell battery found in various electronic devices, and all recognizable brands produce it, such as Toshiba, Maxell, and Energizer. The chemistries of LR44 batteries vary, and each has unique qualities that are essential for the applications for which it is used.
LR44 batteries are 11.6 mm in diameter and 5.4 mm in height. It is a 1.5-volt alkaline single-cell battery with a capacity of around 110mAh and a shelf life of 2-5 years.
These batteries are robust, long-lasting button cells that cannot be recharged. In addition to the chemistry employed, their capacity is influenced by the device’s cut-off voltage.
What Are LR44 Batteries Equivalent To?
Batteries of the same capacity as LR44 are referred to in a few different ways, depending on the manufacturer. When we talk about what the LR44 batteries are equivalent to, we’re referring to battery sizes that we could use instead of the LR44.
LR44 would be directly replaced by GPA76, AG13, L1154, LR1154, and 157. The only difference between these batteries and the LR44 battery is the name. These batteries are all interchangeable.
In addition, although they differ chemically, other batteries can be related to LR44s. These button cells are silver-oxide batteries, and the 303, SR44, SBB9, SR44W, and 357 are a few.
Despite having the same size as an LR44s, the silver oxide chemistry in them provides performance with a shallow draw. These batteries have a greater voltage, around 1.55 volts. They feature a capacity range of 160-200mAh and a longer shelf life of 5 years.
What Are LR44 Batteries Used For?
The LR44 battery is a durable button cell battery, as was already mentioned. It is small in size and inexpensively priced. Because it is so popular for personal use, it is widely accessible in retailers.
The LR44 button cell battery is frequently found in various compact and portable devices. In addition to calculators, thermometers, pistol sights, electronic toys, LED lights, dog collars, and medical equipment, you may use it to make laser pointers, small radios, cameras, hand clocks, toys, and portable gadgets.
Before replacing the batteries in your portable devices, you should consider many aspects. Examples include battery type, measuring dimensions, capacity, maximum voltage or current, shelf life, and battery chemistry.
Silver-oxide batteries are the chosen material for powering watches, calculators, and other small electronic devices. Alkaline batteries are safe for toys, small flashlights, and other similar uses.
Where To Buy LR44 Batteries?
Due to personal use, LR44 batteries are widely used. A large number of different companies produce these batteries, and they are simple to locate in a store.
However, it’s critical to remember that not all LR44 batteries are made equal, and not all sellers are equally committed to quality. Small businesses and private-label battery producers both make this battery.
Only buy your batteries from a major company that sells the highest-quality brands, such as Toshiba, Maxell, or Energizer, to prevent buying low-quality or counterfeit batteries.
For a piece of mind regarding the quality of the products and proper equipment preservation, you can purchase them online from a reliable e-commerce platform with good customer care if you cannot visit the store.
LR44 Batteries vs Lithium Batteries
The active component of lithium batteries is lithium oxide, and the other electrode is typically a lithium intercalation compound, most frequently graphite. A water-based electrolyte likely reacts with lithium compounds or degrades at the cell’s voltages, so the electrolyte is often an organic substance.
LR44 batteries are dry alkaline cells that employ potassium hydroxide and water as the electrolyte and manganese dioxide and zinc as the active ingredients.
Numerous more variances result from the chemical disparities.
The two electrodes undergo separate chemical processes, which results in the varied voltages at which the cells function. Lithium batteries provide a higher open-circuit voltage than alkaline batteries when comparing these batteries’ stable voltage and current levels.
Alkaline batteries run at about 1.5 V/cell, while lithium batteries run at about 3.3 V/cell. As a result, compared to alkaline batteries, lithium batteries often have higher energy densities.
In general, lithiums are a better option for applications involving motion. However, because they last longer than LR44 batteries, they have a competitive edge over those batteries.
For example, alkaline batteries, for instance, work just well as a remote control for the TV in your living room. Lithium is preferable for emergency torches left unused for months or years. It can endure low winter temperatures, lose less power over time, and create more energy when required.
Because lithium batteries are so strong, they are also more harmful to people and the environment, and you ought to utilize them with caution.
However, LR44 batteries don’t contain heavy metals that can contaminate the ground or increase the chance of a ground fill explosion. They are therefore regarded as non-toxic. You can get rid of it with the rest of your regular trash. When disposing of batteries, it is still advisable to follow the correct procedures.
Is An LR44 The Same As A 357?
No, they are not the same. LR44 and 357 batteries have a similar design but function differently. But you can use them interchangeably in many circumstances.
The 357 is silver-oxide chemistry, while the LR44 is an alkaline zinc manganese battery. LR44 batteries frequently cost a little less than 357 batteries.
The 357 is a low-drain battery with a low discharge rate, while the LR44 has a higher self-discharge rate, smaller capacity, and less steady voltage.
LR44 will be the preferred choice with stable discharge if you use it for a long-lasting power device that depletes the battery for days or weeks.
Can I Replace LR44 With AA?
Yes, provided that the voltage remains constant. However, their size and shape are very different.
Different varieties of button cells exist. LR44 has a nominal terminal voltage of 1.5 volts, allowing a single AA to replace a single button cell electronically.

We hope you now thoroughly understand LR44 batteries and replacements battery for lr44, including their features, application, and distinctions from lithium batteries.
Although batteries can readily fit into one another’s devices, selecting the type that is best for yours is crucial. Please check the voltage and size to prevent any problems that could harm your appliance.
