Purpose-Built Power for Industrial Devices

The Tadiran TL-5242/W is a 3.6V lithium thionyl chloride cell rated at 2.1Ah. It arrives with a fitted two-pin connector for direct board mounting. Engineers specify this chemistry for remote sensors, utility meters and tracking units that must run for years without maintenance.

Thermal Behaviour and Power Profile

The cell operates from -60°C to +85°C while maintaining a stable high voltage through most of its life. Self-discharge stays below one percent per year at 20°C, so stored spares remain ready after a decade. The non-flammable electrolyte adds safety in sealed enclosures.

Connector and Handling Notes

The pre-wired connector removes the need for solder tabs or custom holders, cutting assembly time on the production line. Because the chemistry is primary only, recharging attempts are hazardous and must be prevented by firmware or hardware lockout. Store stock below 30°C in a dry, ventilated area.

Questions about this item

How is the 2‑pin connector fitted and what polarity mistake should I avoid?

The battery ships with a pre‑attached 2‑pin connector; match the red lead to positive and black to negative on the device header to prevent reverse‑polarity damage.

What storage conditions preserve the 10‑year shelf life and when should the cell be replaced?

Store in a clean, dry, ventilated area below 30 °C; the Li‑SOCl₂ chemistry self‑discharges under 1 % per year at 20 °C, so replace after 10 + years or when voltage drops below 3.6 V under load.

At what temperature does the 3.6 V 2.1 Ah cell hit its continuous‑discharge limit first?

The rated operating range is –60 °C to +85 °C; sustained loads near the upper limit will trigger the voltage‑drop limit before the 2.1 Ah capacity is fully delivered.
