• Small medical devices such as glucose meters and thermometers
• Hearing aids, remote controls and key fobs with SR57 size

Key specifications

• Chemistry: Silver oxide
• Nominal voltage: 1.55V
• Form factor: Button cell (SR57 size)
• Typical use: Low-drain devices
• Storage: Long shelf life when stored in original packaging at room temperature

How to use

Ensure the device is powered off or in a safe state before replacing the battery. Open the battery compartment according to the device manufacturer’s instructions, remove the depleted SR57 cell, and insert the new Energizer SR57 with correct polarity indicated in the compartment. Close the compartment securely and verify correct operation. Dispose of the used cell according to local regulations for battery recycling or hazardous waste.

Usage recommendations

Store unused cells in their original packaging at moderate room temperature and avoid exposure to extreme heat, humidity or direct sunlight. Replace batteries in pairs if the device uses multiple cells, and check device manufacturer's guidance for specific installation notes and polarity markings.
