The Maxell ER6C is a primary (non‑rechargeable) AA‑size cylindrical lithium cell engineered for long‑term, low‑drain applications where stable voltage, high energy density, and reliability are essential. The version with a connector is pre‑fitted with insulated leads and a plug (often JST or Hirose type) for quick, secure installation in devices such as PLC memory backup modules, CNC controllers, industrial automation systems, and metering equipment. It offers excellent shelf life and dependable performance across a wide temperature range.
