Button cell battery Energizer LR41 (also 392/384) silver oxide 1.5V

Energizer LR41 (also sold as 392/384) is a silver‑oxide button cell battery with a nominal voltage of 1.5 V. Designed for small electronic devices, this compact cell provides steady voltage and stable discharge characteristics suitable for timekeeping, low-current displays and precision electronics. Its small diameter and low profile make it compatible with a wide range of watches, calculators, medical instruments and small consumer electronics where a reliable, compact power source is required.

Advantages

The silver‑oxide chemistry delivers a flat discharge curve and consistent voltage throughout most of the battery life, supporting devices that need stable power. The LR41 design offers compact dimensions for tight battery compartments and reliable contact with device terminals. Energizer manufacture and quality control help ensure predictable performance, minimal leakage risk under normal usage, and shelf stability for storage before installation.

Suitable for

• Wristwatches and small timepieces
• Calculators and basic electronic displays
• Medical devices such as thermometers and hearing aids (as specified by device manuals)
• Toys, laser pointers and small LED lights
• Replacement in devices originally specified for LR41 / 392 / 384 cells

Key specifications

• Chemistry: silver‑oxide
• Nominal voltage: 1.5 V
• Form factor: button cell (low profile, small diameter)
• Typical use: low‑to‑moderate current drain devices
• Storage characteristics: long shelf life when stored in original packaging at moderate temperatures
• Operational behavior: flat discharge curve for stable voltage output

How to use

Verify the device manual or existing battery marking to confirm LR41 / 392 / 384 compatibility before replacement. Power down the device if recommended, open the battery compartment using the appropriate tool, and remove the depleted cell carefully to avoid shorting contacts. Install the new battery with correct polarity orientation (+ and −), ensuring secure contact with terminals. Close the compartment and test the device operation. Dispose of used button cells in accordance with local battery recycling and disposal regulations.

Usage recommendations

Store unused LR41 cells in their original packaging at room temperature and away from metal objects. Replace batteries in sets at the same time if multiple cells are used in a device. Do not attempt to recharge primary silver‑oxide cells or expose them to high heat. For medical devices, follow device manufacturer instructions regarding approved battery types and replacement intervals.
