Rechargeable battery ANSMANN ER17500 3.6V Lithium Thionyl Chloride (ER17500)

ANSMANN ER17500 3.6V Lithium Thionyl Chloride (ER17500) is a primary rechargeable-format battery designed to provide a stable 3.6V output for long-term power supply applications. The cell offers low self-discharge and consistent voltage under low-current and intermittent-load conditions, and its compact cylindrical format simplifies installation in small devices and instrument housings.

Advantages

The battery delivers a stable nominal voltage of 3.6V with reliable performance over extended periods, especially in low-drain and pulse-load scenarios. It has low self-discharge characteristics that preserve capacity during storage. The compact cylindrical form factor enables straightforward mechanical integration into a variety of device compartments. The chemistry provides a wide operating temperature range and maintains voltage stability that supports memory backup, remote sensors, and metering electronics.

Suitable for

• Industrial sensors and remote monitoring devices
• Utility meters and data logging equipment
• Memory backup for controllers and instrumentation
• Security devices and alarm systems with low- to moderate-current draw
• Other low-current, intermittent-load electronics

Key specifications

• Nominal voltage: 3.6 V
• Chemistry: Lithium thionyl chloride
• Cell format: cylindrical
• Typical use: low-current and intermittent-load applications
• Storage behavior: low self-discharge for long shelf life
• Temperature characteristics: suitable for a wide operating temperature range

How to use

Install the battery following the device manufacturer’s polarity markings and mounting instructions. Ensure contacts are clean and free of corrosion before insertion. For devices with replaceable cells, power down equipment if recommended, and avoid applying excessive mechanical force when seating the battery. Observe recommended storage conditions to preserve shelf life and avoid mixing with different chemistry cells in the same device.

Usage recommendations

Use this battery in applications that require long-term, stable 3.6V supply at low average currents. Store unused batteries in a cool, dry place and keep them in original packaging until installation. For critical systems, verify compatibility with device specifications and consider periodic functional checks to confirm remaining capacity.
