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.
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.
Here is a list of the LR44 battery specifications:
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.
The LR44 battery is a dependable source of power for a wide range of devices. It has some of the following features:
This LR44 battery is commonly installed in various equipment for its compact dimension and stabilization. A few common use cases are:
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.
