This guide is for anyone seeking reliable, compact power for their small electronic devices. The Duracell LR44 alkaline battery offers consistent 1.5V performance, making it a versatile choice for a wide range of gadgets. Its key benefit is broad compatibility, but users must always verify the required battery type for their specific device to ensure proper function.
Alkaline Chemistry: Provides stable and consistent power output for various low-drain and high-drain applications.
Standard 1.5V Voltage: Delivers the common voltage required by many small electronic devices.
Compact Size (11.6mm x 5.4mm): Its small dimensions make it ideal for miniature electronics where space is limited.
Wide Cross-Compatibility: Known by numerous alternative names such as A76, AG13, 357, SR44, and more, ensuring broad usability.
Duracell Reliability: Manufactured by a trusted brand known for battery quality and longevity.
Sealed Packaging: Supplied in secure, sealed packets to maintain freshness and prevent premature discharge.
Broad Device Compatibility: Fits many common small electronics, reducing the hassle of finding specific battery types.
Reliable Performance: Duracell's alkaline chemistry provides steady power for device operation.
Readily Available: Widely stocked in stores, making replacements easy to find.
Cost-Effective: Generally more affordable than specialized battery types.
Not Rechargeable: These are single-use batteries and must be disposed of after depletion.
Limited for High-Drain Devices: While suitable for many, extremely high-drain devices might benefit from specific lithium alternatives for longer life.
Potential for Confusion: The many alternative names can sometimes make initial identification challenging.

Duracell LR44 batteries are workhorses for a multitude of small electronic items. They are designed to deliver reliable, consistent power, which is crucial for devices that require stable voltage to function correctly. Their alkaline composition ensures a steady discharge curve, meaning your devices will perform predictably until the battery is depleted.
Calculators: Powering both simple and scientific calculators.
Watches: Ideal for analog watches and some digital models.
Small Toys and Games: Keeping children's small electronic toys and handheld games operational.
Laser Pointers: Providing consistent beam intensity.
Medical Devices: Used in some blood glucose meters, thermometers, and small hearing aids.
Key Fobs: Often found in car key fobs and remote controls.
Observe Polarity: Always insert batteries with the correct positive (+) and negative (-) orientation as indicated by your device.
Replace in Sets: For devices using multiple batteries, it's best to replace all batteries at the same time to ensure uniform performance and prevent issues caused by uneven discharge.
Avoid Mixing Brands/Types: Do not mix LR44 batteries with different brands or types (e.g., carbon-zinc, lithium) in the same device, as this can lead to reduced performance or leakage.
Locate Battery Compartment: Identify the battery compartment on your device, usually indicated by a small door or panel.
Open Compartment: Use a small screwdriver or coin if necessary to open the compartment.
Remove Old Batteries: Carefully remove any old batteries, noting their orientation.
Insert New Batteries: Insert the Duracell LR44 batteries, matching the positive (+) and negative (-) terminals with the indicators in the compartment. The flat, wide side is typically the positive (+) end.
Close Compartment: Securely close the battery compartment.
Check Device Manual: Always refer to your device's user manual or existing battery to confirm it requires an LR44 or one of its many equivalent types (e.g., A76, AG13, SR44, 357, V13GA, EPX76).
Voltage Match: Ensure your device requires a 1.5V battery. While LR44 and SR44 (silver oxide) often fit the same compartment, SR44s provide a slightly more stable voltage profile for precision devices.
Storage: Store batteries in their original sealed packaging in a cool, dry place at room temperature. Avoid extreme temperatures.
Keep Away from Children: Batteries can be a choking hazard, especially for small children. Store them out of reach.
Avoid Short Circuits: Do not carry loose batteries in pockets or purses with metal objects like coins or keys, which can short-circuit them.
Disposal: Dispose of used batteries according to local regulations. Many communities have battery recycling programs.
