Battery ANSMANN ER26500 3.6V Lithium Thionyl Chloride industrial primary cell

ANSMANN ER26500 is a 3.6V lithium thionyl chloride (Li-SOCl2) primary cell designed for long-term, low-drain industrial applications. This non-rechargeable battery offers high energy density and a stable nominal voltage, making it appropriate for devices that require reliable standby power and extended shelf life. The cell is manufactured to meet industrial performance expectations and is suitable for environments where maintenance access is limited.

Advantages

The battery delivers a high energy-to-volume ratio and maintains a steady voltage under low to moderate load conditions, which supports consistent operation of meters, sensors and security modules. It has a long shelf life and low self-discharge characteristics, reducing the need for frequent replacement. The cell’s chemistry provides good performance over a wide temperature range and stable output during long-term storage and intermittent use.

Suitable for

• Utility meters (electricity, gas, water)
• Remote sensors and data loggers
• Security and alarm systems
• Industrial monitoring and telemetry devices
• Backup power for low-drain electronics

Key specifications

• Nominal voltage: 3.6 V
• Cell chemistry: Lithium thionyl chloride (Li-SOCl2)
• Primary (non-rechargeable) cell
• High energy density suitable for long-term use
• Low self-discharge for extended shelf life
• Designed for low to moderate continuous drain and pulse loads
• Suitable operating temperature range for industrial applications

How to use

Install the ANSMANN ER26500 according to the device manufacturer’s polarity and mounting instructions. Use the cell in devices designed for primary lithium-thionyl chloride chemistry and avoid attempting to recharge. For optimal performance, ensure correct contact pressure and clean battery terminals before installation. Replace the cell with the same chemistry and size when end-of-life is reached, taking care to observe proper disposal or recycling regulations for lithium primary batteries.

Usage recommendations

Store in a cool, dry place away from direct heat sources. Avoid short-circuiting the terminals and protect the cell from mechanical damage. When used in low-drain or standby applications, periodic inspection of the host device and battery condition is recommended to ensure continued operation.
