  • Battery type1/2 AA Lithium
  • Reliable 3.6 V output backed by 1200 mAh capacity
  • Wide -55 °C to +85 °C operating range suits harsh environments
  • 24-cell pack provides long-term supply for meters and sensors
  • Li-SOCl₂ chemistry delivers stable voltage over extended storage
  • Compact 14.5 mm diameter fits standard 1/2 AA compartments

DUSLAN ER14250 1/2 AA Lithium Pack

This 24-pack supplies primary lithium thionyl chloride cells rated at 3.6 volt nominal voltage and 1200 mAh capacity. Each 1/2 AA battery measures 14.5 mm diameter by 25.25 mm height and weighs 12 g. The chemistry delivers stable output across an operating range of -55C to +85C.

Build Integration for Long-Life Backup

These cells suit board-level backup, utility meters, medical devices, military or aerospace gear, telecom modules and LED lighting where multi-year service is expected. The 3.66 volt open-circuit voltage at +20C fits circuits designed for 3.6 volt nominal rails. Solder tabs must be attached in seconds to avoid heat damage.

Non-Rechargeable Chemistry Constraints

The lithium thionyl chloride chemistry is not rechargeable; any charging attempt creates a safety hazard. Storage must stay at or below +30C in a clean, dry, ventilated area. If open-circuit voltage falls below the target level, a brief 100 mA discharge can restore usable voltage. Buyers needing rechargeable cells or higher single-cell voltage must choose a different chemistry.

Questions about this item

How long does the 1200 mAh capacity last under a continuous 1 mA drain?

The nominal 3.6 V rating is measured at 1 mA and +20 °C, so the 1200 mAh figure represents the typical capacity at that load and temperature.

What is the self-discharge rate when the pack is stored at +30 °C?

Storage at or below +30 °C is recommended; lithium thionyl chloride chemistry typically loses only a few percent of capacity per year at that temperature.

Which devices already need a 14.5 mm diameter, 25.25 mm height cell with tabs?

Equipment designed for ER14250, LS14250, TL-5902, TL-2150 or equivalent 1/2 AA lithium thionyl chloride batteries will accept these cells directly.
