Design and Construction

The LR44 is engineered with a stainless steel casing that protects the internal chemistry from corrosion and mechanical stress. The metal shell also provides a stable electrical contact, ensuring low resistance and reliable performance even in high‑current applications. The internal structure consists of a manganese dioxide cathode, zinc anode, and an alkaline electrolyte that maintains ion flow throughout the battery’s life.

Performance Characteristics

Stable Voltage Output: The LR44 maintains a near‑constant 1.5 V output until the terminal voltage drops below approximately 0.9 V, at which point device operation may be affected.

Low Self‑Discharge: Alkaline chemistry offers a self‑discharge rate of roughly 1–2 % per month, making it suitable for devices that are used infrequently.

High Energy Density: With a capacity of about 110 mAh, the LR44 delivers sufficient energy for small sensors, key fobs, and other low‑power electronics.

Temperature Range: Operates effectively from –20 °C to +60 °C, ensuring reliability in both cold and hot environments.

Typical Applications

• Digital Watches: The compact size and steady voltage make it ideal for wristwatches.
• Calculators: Many handheld calculators use LR44 cells for their low power consumption.
• Remote Controls: Keyless entry systems and remote controls often rely on button cells.
• Medical Devices: Small medical instruments such as blood pressure monitors and pulse oximeters use LR44 batteries.
• Security Systems: Motion sensors and alarm panels frequently incorporate LR44 cells.
• Electronic Toys: Low‑power toys and educational kits benefit from the LR44’s reliability.

Installation Tips

Polarity Check: Always verify the correct orientation before insertion; reversing polarity can damage the device.

Secure Fit: Ensure the battery contacts are clean and free of corrosion to maintain optimal electrical contact.

Avoid Physical Shock: While the stainless steel casing is robust, repeated impact can compromise internal integrity.

Environmental Considerations

The GP LR44 is a non‑rechargeable alkaline battery, which means it should be disposed of according to local hazardous waste regulations. Recycling programs for alkaline batteries are available in many regions, helping reduce environmental impact.

Compatibility Notes

The LR44 is interchangeable with other common button cell sizes such as AG13, 357, and L1154. However, always confirm device specifications before substitution to avoid performance issues.

Summary

The GP Batteries ALKALINE BUTTON CELL LR44 delivers reliable, long‑lasting power for a wide array of small electronic devices. Its stainless steel construction, stable voltage output, and proven alkaline chemistry make it a trusted choice for consumers seeking dependable performance in compact form.
