Duracell 504424 Battery button cell LR44 1.5 V 2 pcs content_copy

The Duracell LR44 is a single-use battery in the format of a button cell, designed for small electronic devices with low power consumption. The manufacturer Duracell offers this battery in a pack containing 2 pieces, delivered in a clear packaging. The battery is based on alkaline technology and provides a nominal voltage of 1.5 V. The colour of the batteries is silver, which is typical for button cells of this design. The packaging has a width of 84 mm, a depth of 6 mm, and a height of 120 mm, with the total weight of the package being 8 g.

Applications
The LR44 battery is commonly used in compact electronic devices, such as calculators, watches, remote controls, medical measuring devices, or small sensors. Due to its small dimensions and high energy density relative to its size, it is particularly suitable for applications where space and energy efficiency are critical. The battery is not designed for devices with high power consumption or continuous use.

Functions and Equipment in Detail
The battery is a single-use battery, meaning it is not rechargeable once depleted. The alkaline technology ensures stable voltage throughout its entire lifespan and high energy density. The nominal voltage of 1.5 V corresponds to the standard for many small electronic components. The battery is packaged in a blister pack, which makes the contents visible while also protecting against mechanical damage.

Technology Explained Simply
The alkaline technology is based on a chemical reaction between zinc and manganese dioxide in an alkaline electrolyte solution. This technology offers a longer lifespan and constant voltage compared to other button cell technologies such as zinc-carbon. The voltage of 1.5 V is sufficient for most small electronic devices, as these typically require only small amounts of current. The battery is not suitable for use in devices with high current surges, as this would significantly reduce its lifespan.

Compatibility and Accessories
The LR44 is a universally common format used in many devices. It is compatible with devices requiring a button cell in the format LR44 or also AG13, SR44, 357, or 156 — although exact compatibility may vary depending on the manufacturer and device. The use of replacement batteries in other technologies (e.g. silver oxide) is possible, but not always recommended, as it may lead to voltage differences. The battery is not compatible with other battery types such as lithium button cells or NiMH rechargeable batteries.

Installation and Mounting
Installation is carried out by simply inserting the battery into the designated battery compartment of the device. The polarity (positive and negative terminals) is marked on the battery and must be observed according to the device’s instructions. The battery is not intended for use in devices subject to high mechanical stress or in environments with high humidity or temperature, unless the device itself is designed for such conditions.

Advantages in Operation
The alkaline technology offers a longer lifespan compared to zinc-carbon batteries and maintains a constant voltage, which is important for the reliability of devices. The single-use battery is cost-effective for applications where the battery does not need to be replaced frequently. Packaging in a blister pack allows for easy storage and identification of the product. The battery is intended for indoor use, as no specific protection ratings such as IP rating are indicated.
