    What is an LR44 Battery?

    The LR44 battery is a tiny button cell battery widely used across a range of low-power applications from watches and calculators to toys and even medical applications. This alkaline button cell is one of the most common button cells used in small electronic devices. The letters LR are commonly used in its name to designate the alkaline chemistry; so for example, "AA batteries" are generally described as "AA alkaline" batteries.

    LR44 Battery

    Along with the LR44 there are many equivalent type batteries also cross-referenced as: AG13, A76 and others, which can be used as a replacement in certain devices. Now, we're going to explore the LR44 battery, looking into its specifications, how it works, its uses, and how it compares to other button cells such as the CR2032.

    Specifications

    Here is a list of the LR44 battery specifications:

    • Voltage: 1.5V
    • Volume: About 110-120mAh consecutively (mAH, milliampere-hour)
    • Diameter: 11.6 mm
    • Height: 5.4 mm
    • Weight: About 1.85 grams
    • Chemistry: Alkaline

    The LR44 has a regular voltage of 1.5V that is ideal for devices that require a flat, reliable power source. 110mAh of a capacity is suitable for many low drain applications, and its tiny size makes it fit into even the smallest of devices.


    LR44 Battery Function and Features

    The LR44 battery is a dependable source of power for a wide range of devices. It has some of the following features:


    • Long Span Life: The LR44 battery has up to 5 years of life span. predicate 0023 Thus, it is suitable for that kind of rarely used apparatus.
    • Constant Voltage Output:Provide stable 1.5V output until the end of battery life, keeping your devices such as watches, clocks, and calculators running without any interruption.
    • Cheap: The LR44 is cheap and popular for the button cell market.
    • Readily Available: Similar to the previous battery, you can find LR44 batteries produced by brands like Energizer MR AG and Duracell in almost any store.


    LR44 Battery Applications

    This LR44 battery is commonly installed in various equipment for its compact dimension and stabilization. A few common use cases are:

    • Wristwatches: The LR44 is commonly used in anolog wristwatches. The small size and long life also are great for timepieces that are not worn often and do not get as much light.
    • Toys: LR44 battery is also suitable for small electronic toys and many novelty items, it's got just enough juice to power those little LED's or noisy sound maker.
    • Calculator: The LR44 button cell is commonly used in handheld calculators for its self-discharge rate and long service life.
    • Laser Pointers : Laser pointers are commonly used with the LR44 battery, as it is small and provides steady power.
    • Medical Devices: Certain small medical devices, like thermometers and glucose meters, are designed to consume low power and, therefore, use LR44 batteries.


    LR44 vs Other Button Cells

    To put this in perspective, that the LR44 falls, we need to compare it to another type of button cell that's widely used - the CR2032.

    Voltage The voltage of the LR44 is 1.5V while that of the CR2032 is 3V, so if your devices are in need of a higher voltage then you will definitely want the CR2032.

    Package size: 37 x 37 x 17mm Size: 11.6 x 5.4mm in diameter x 5.4mm high. The CR2032 on the other hand is wider (20mm) and thinner (3.2mm).

    power: The CR2032 has a much larger capacity of about 220mAh and can last much longer than LR44 which is about 110mAh.

    Chemistry: The LR44 is alkaline chemistry, and the CR2032 is a lithium button cell. Lithium batteries such as the CR2032 will typically have a longer battery life but are more expensive.

    Applications: LR44 is an all-purpose battery suitable for watches, toys and small electronic devices, while the CR2032 is designed for applications that require higher voltage, such as motherboards, fitness watches and keyless entry remotes.

    Although LIR2032 is of higher capacity and longer life, LR44 is a better battery for devices with low current consumption because it is fragile, the size is small, and the price is lower.


    Related Button Cell Models

    In addition to the LR44, there are several other button cell models that are similar in size and can be used as replacements in certain devices. Some common equivalents or replacements include:
    AG13: The AG13 is another name for the LR44. These batteries are interchangeable in many devices that require the LR44, and some brands use the AG13 label instead of LR44.
    A76: The A76 is also an equivalent to the LR44, and it's often used interchangeably with the LR44 in devices like watches and calculators.
    SR44: The SR44 is a silver-oxide button cell, which is often used as a replacement for the LR44. It provides a more stable voltage over time but tends to be more expensive.
    V13GA: This is another equivalent alkaline battery that can serve as a replacement for the LR44 in many devices.
    It's essential to check your device's specifications to ensure you choose the correct replacement battery, as some models may require a different type of button cell, such as the SR44 for improved performance over time.

    How to Choose the Right Battery

    Choosing the correct button cell battery depends on several factors:
    Size: Ensure the battery fits properly in your device. The LR44 is commonly used in devices with very small compartments, so check the size before purchasing.
    Power Requirements: Devices like toys and watches that only require low energy can use the LR44. However, if your device needs more power or a higher voltage, consider a CR2032 or another lithium battery.
    Cost: If you are on a budget, the LR44 is usually the most affordable option. For longer-lasting power, you may want to consider more expensive lithium batteries like the CR2032.
