Lithium Thionyl Chloride Battery EVER ER14250 3.6V 1200mAh

The EVER ER14250 is a 3.6V lithium thionyl chloride battery with a nominal capacity of 1200mAh, intended for long-life, low-drain and intermittent-use applications. The cell provides a stable voltage profile and extended shelf life, making it suitable for devices that require dependable standby power and occasional discharge cycles. It is constructed for consistent performance across a wide temperature range and for applications where replacement or maintenance must be infrequent.

Advantages

This lithium thionyl chloride battery delivers high energy density in a compact cylindrical format, offering long storage life and low self-discharge. It maintains reliable voltage under low to moderate continuous loads and supports pulse discharge for intermittent operation. The cell is designed for stable performance over a broad temperature range and is optimized for devices that need long-term, maintenance-free power.

Suitable for

• Memory backup in electronic systems and data retention modules
• Utility metering, smart meters and remote reading devices
• Security systems, alarms and access control devices
• Industrial sensors, telemetry and monitoring equipment
• Low-drain portable instruments and long-term field devices

Key specifications

• Nominal voltage: 3.6 V
• Nominal capacity: 1200 mAh
• Chemistry: lithium thionyl chloride (Li-SOCl2)
• Cell format: cylindrical (ER14250 size)
• Typical operating temperature range: wide temperature tolerance suitable for industrial and outdoor use
• Self-discharge: very low, suitable for long shelf life
• Suitable discharge modes: low continuous current and intermittent/pulse loads

How to use

Install the battery following the device manufacturer’s polarity markings and use appropriate holders or contacts to ensure secure connection. For devices with low continuous draw or intermittent pulses, use the battery as primary power or backup source according to system design. Observe device specifications for maximum allowed current draw and avoid using the cell in high-drain applications for which it is not intended. Store unused batteries in a cool, dry place and install new cells before the end of their recommended shelf life to ensure reliable operation.

Usage recommendations

Do not attempt to recharge primary lithium thionyl chloride cells. Dispose of used batteries according to local regulations. Avoid short-circuiting, exposure to fire, or mechanical damage. For best results, match battery type to the device’s current profile and temperature conditions, and consult device documentation when replacing existing cells.
