This is a non‑rechargeable lithium‑thionyl chloride (Li‑SOCl₂) C‑cell battery modeled after the Tadiran TL‑5920. Featuring a compact cylindrical form, it delivers high energy in a robust design. While branded “copy,” it offers a cost‑effective alternative for low‑drain, long‑term applications such as utility meters, memory backup, security modules, and remote sensors.
Features:
Nominal voltage of 3.6 V with large capacity (~8.5 Ah)
Stable output throughout most of the discharge cycle
Extended shelf life (approx. 8–10 years) with minimal self-discharge
Wide temperature range: –55 °C to +85 °C
Low continuous drain (~3 mA) and moderate pulse support (~400 mA)
Durable hermetically sealed steel housing
