The Maxell ER17/50 is a primary (non‑rechargeable) lithium thionyl chloride (Li‑SOCl₂) cell. It’s built for long‑duration, low‑drain applications that demand stability, high energy density, and exceptional operating life — even in extreme temperatures. The 2‑pin white connector version allows easy installation into compatible equipment without soldering.
Common uses include:
