The Duracell LR43 Coin Button Cell Battery is engineered for reliable performance in devices that require a consistent 1.5V power output. Its primary applications are in gadgets where space is at a premium and a steady, long-lasting charge is necessary.
Calculators: Provides the necessary power for basic and scientific calculators, ensuring consistent display and function.
Fever Thermometers: Critical for accurate temperature readings, where stable power translates directly to reliable measurement.
Pulse Monitors: Used in some compact medical devices to ensure continuous monitoring and display of vital signs.
Small Electronic Games & Toys: Powers specific miniature electronics where the LR43 cell is specified.
Watches & Clocks: Certain models of watches or small desk clocks may utilize this battery type.
Users can expect reliable, steady power throughout the battery's life cycle, which is characteristic of Duracell's alkaline chemistry. While the exact lifespan depends on the power requirements of the specific device, the LR43 is optimized for low to moderate current drains. For critical devices like medical thermometers, replacing the battery at the first sign of performance degradation (e.g., dim display, slow response) is recommended to maintain accuracy.
Ensuring proper installation and care for your Duracell LR43 battery will maximize its performance and safety.
Identify Correct Slot: Locate the battery compartment on your device. Most small electronics have a cover that can be opened with a small screwdriver or coin.
Observe Polarity: Note the + and - markings inside the compartment and on the battery. Ensure the positive (+) side of the battery aligns with the positive terminal in the device, and the negative (-) side with the negative terminal. The positive side is usually the larger, flat top of the coin cell.
Insert Gently: Carefully place the battery into the compartment. Do not force it, as this can damage the battery or the device.
Secure Compartment: Close the battery compartment cover securely. For child-resistant compartments, ensure it clicks into place or is screwed shut.
Check Your Device Manual: Always refer to your device's user manual or existing battery to confirm that LR43 (or an equivalent, such as 186, V12GA, PX86A, A86) is the required battery type. Using an incorrect battery size or voltage can damage your device or prevent it from functioning.
Voltage Match: The Duracell LR43 provides 1.5 volts. Ensure your device is designed for this voltage.
Store Properly: Keep unused batteries in their original packaging in a cool, dry place at room temperature. Avoid extreme temperatures or humidity.
Keep Out of Reach of Children: Due to their small size, button cells can be easily swallowed. Store them securely away from infants and young children. If ingested, seek immediate medical attention.
Dispose Responsibly: Never dispose of batteries in general household waste. Follow local regulations for battery recycling, which often involves taking them to designated collection points.
Avoid Short Circuits: Do not store loose batteries together or with metal objects, as this can cause a short circuit, leading to heat generation or leakage.
Handle with Clean Hands: Oil and dirt from hands can potentially affect battery terminals. Handle batteries with clean, dry hands.
