Tadiran TL-5920/S lithium thionyl chloride battery

The Tadiran TL-5920/S is a 3.6 volt C-size primary cell delivering 8.5 Ah capacity in a 26500 form factor. It suits metering, tracking, alarm and industrial IoT devices that demand multi-year service without replacement.

Verify voltage and current needs before ordering

Confirm the host device accepts a single 3.6 volt lithium thionyl chloride cell with button-top termination. The maximum recommended continuous current is 230 mA and pulse capability is 400 mA; ensure your load stays within these limits. Do not attempt to recharge this non-rechargeable chemistry.

Compatible part-number cross-reference included

The datasheet lists ER26500, LS26500, LS26500C, TL-4920, TL-2200, SB-C01, SB-C02, SL-770, XL-140F, XL-145F and PT-2200 as direct replacements, simplifying procurement when existing stock uses alternate codes.

Questions about this item

Does the TL-5920/S ship as a single cell or do I need to buy a holder and wiring separately?

The listing is for one button-top C-size cell measuring 26 mm by 50 mm; no holder, leads or connectors are included.

The supplier title shows ER26500 and LS26500 — are those different versions or the same capacity?

Both designations refer to the same 3.6 V 8.5 Ah lithium thionyl chloride chemistry; choose whichever part number matches your equipment manual.

With a 230 mA continuous rating, can this cell run a 500 mA sensor for short bursts?

The cell supports pulses up to 400 mA, so a 500 mA load exceeds the specified pulse capability and is not recommended.
