Battery ANSMANN ER14250 Lithium-Thionylchloride 3.6V 1/2AA

ANSMANN ER14250 is a 1/2AA format primary lithium-thionylchloride battery with a nominal voltage of 3.6V, developed for long-term, low-drain and intermittent use. The cell is designed to deliver dependable energy for applications such as memory backup, utility metering, alarm systems and industrial electronics where long shelf life, wide operating temperature range and low self-discharge are critical. Its compact cylindrical size allows integration into space-constrained devices while providing high energy density compared with similarly sized primary cells.

Advantages

The battery offers a high energy-to-volume ratio and very low self-discharge, enabling stable performance over extended storage and service periods. It tolerates a wide temperature range and provides reliable operation in low-drain and intermittent load profiles typical of metering, backup and sensor circuits. The chemistry results in predictable voltage characteristics and long shelf life, reducing maintenance and replacement frequency in remote or hard-to-access installations.

Suitable for

• Memory backup in electronic equipment and RTC modules
• Gas, water and electricity meters
• Security and alarm systems
• Industrial sensors, transmitters and data loggers
• Remote monitoring devices and telemetry

Key specifications

• Cell type: lithium-thionylchloride (primary)
• Nominal voltage: 3.6 V
• Format: 1/2AA (cylindrical)
• Designed application: low-drain and intermittent loads
• Typical characteristics: high energy density, low self-discharge
• Operating temperature range: wide tolerance for varied environmental conditions
• Shelf life: long-term storage capability with minimal capacity loss

How to use

Install the battery observing correct polarity to avoid damage to the host device. Use the cell in devices that match the battery's intended low-drain or intermittent duty cycle; continuous high-current loads will significantly reduce service life. For optimal performance, follow device manufacturer instructions regarding battery replacement intervals and storage conditions. Dispose of used cells in accordance with local regulations for lithium primary batteries.

Recommendations

Store unused batteries in a cool, dry place and avoid exposure to high temperatures and humidity. Before installing, verify compatibility with the device's voltage and load profile. For installations in critical or remote systems, consider periodic checks and keep spare cells on hand to ensure uninterrupted operation.
