Description
The Tadiran TL‑2155/S‑BP is a high‑reliability 3.6V lithium thionyl‑chloride (Li‑SOCl₂) 2/3AA battery engineered for long‑life performance in demanding industrial and security applications. Built on Tadiran’s proven TL‑series chemistry, it delivers exceptionally low self‑discharge, enabling operational lifespans of 10–20+ years in low‑drain devices. Its compact 2/3AA size provides strong energy density while maintaining stable voltage output across a wide temperature range, making it ideal for wireless sensors, memory backup, utility metering, and remote monitoring equipment. The TL‑2155/S‑BP features a bobbin‑type construction for maximum longevity, high resistance to leakage, and reliable operation in harsh environments where maintenance access is limited.
