1/2 AA lithium thionyl chloride cell
The DUSLAN ER14250 is a 3.6 volt primary lithium battery with a nominal capacity of 1200 mAh. It fits devices that require the 1/2 AA form factor and operates reliably from minus 55 to plus 85 degrees Celsius. Typical applications include backup power for circuit boards, utility meters, medical equipment and LED lighting. This cell is not rechargeable and must not be placed in a charger.
No accessories or software included
The product is supplied as a single bare cell without tabs, holders, cables or any configuration software. Integration into a device therefore requires separate procurement of a suitable battery holder or direct soldering to the printed circuit board within a few seconds to avoid heat damage. No firmware, drivers or management utilities are provided or needed for this primary chemistry.
Limits of primary lithium chemistry
As a non-rechargeable lithium thionyl chloride cell, the ER14250 cannot be recharged; attempting to do so creates a safety hazard. Self-discharge is very low, but the supplier recommends storage below plus 30 degrees Celsius in a clean, dry, ventilated area to preserve the 3.66 volt open-circuit voltage. The 14.5 millimetre diameter and 25.25 millimetre height fix the mechanical envelope, so compartments sized for other 1/2 AA variants must be verified before use.

Questions about this item
When will the 1200 mAh Li-SOCl2 cell need replacement in a backup circuit?
Replace when open-circuit voltage drops below the 3.6 V your circuit requires; the 1200 mAh capacity determines how long that takes in your specific load.
What thermal limit appears first during continuous 100 mA discharge?
The 85 °C operating ceiling is reached before any voltage sag; the cell is rated to +85 °C and storage must stay under +30 °C.
Does the 14.5 mm × 25.25 mm primary lithium cell generate noticeable heat or noise during all-day metering duty?
No audible noise; self-heating at typical meter currents stays well inside the -55 °C to +85 °C range, so the case remains near ambient.
