DUSLAN ER14250 1/2 AA 3.6V Lithium Battery 1200mAh 16-Pack

SKU CH-MKZN-176VT

Sixteen 1/2 AA lithium thionyl chloride cells deliver 3.6 V and 1200 mAh for backup, metering and industrial use

  • Reliable backup for circuit boards with 1200 mAh capacity
  • Wide operating range from -55C to +85C for harsh environments
  • 6 V nominal voltage suits metering and telecom devices
  • 16-pack delivers long-term supply for medical and aerospace uses
  • Compact 14.5 mm diameter fits 1/2 AA compartments easily

16-Pack ER14250 1/2 AA 3.6V Lithium Battery

This 16-pack supplies primary lithium thionyl chloride cells in the 1/2 AA form factor. Each unit delivers a nominal 3.6 volts and 1200 mAh capacity for long-duration, low-current applications. The chemistry suits devices that must run for years without maintenance such as utility meters, alarm panels or industrial sensors. Buyers needing rechargeable cells or higher pulse currents should choose a different chemistry.

Operating Range -55C to +85C and Storage to +30C

The cells operate reliably from -55C up to +85C, covering outdoor and harsh-environment deployments. Storage temperature should not exceed +30C to preserve shelf life and voltage stability. As primary cells they generate no heat during discharge and require no cooling provisions. The low self-discharge of the lithium thionyl chloride system supports multi-year service intervals.

Compatible Replacements Listed

The datasheet cross-references numerous Tadiran, Saft, Toshiba, Sonnenschein and other part numbers including TL-5902, LS-14250 and ER3v equivalents. This simplifies sourcing for maintenance teams replacing legacy power sources. Soldering tabs must be completed within a few seconds to avoid internal damage. The batteries are not rechargeable and must never be placed in a charger.

Questions about this item

How do I install the ER14250 1/2 AA battery and what soldering mistake should I avoid?

Insert the 14.5 mm diameter by 25.25 mm height cell with correct polarity; finish tab soldering in a few seconds to prevent heat damage.

What maintenance or replacement will the 1200 mAh lithium thionyl chloride cells need later?

These primary cells are not rechargeable; replace all 16 units when voltage drops below the 3.6 V nominal level required by your device.

What limit appears first during sustained use at the 1 mA nominal drain?

The 1200 mAh capacity sets the runtime limit; continuous 1 mA draw at +20 °C will deplete the pack in roughly 1200 hours.
