15-pack 1/2AA lithium backup cells

This pack supplies fifteen CR14250SE lithium batteries rated at 3V and 1800mAh each. They are built for industrial equipment such as PLCs, CNC machines, servo controllers, programmers and metering devices that need long-life primary power.

Non-rechargeable chemistry and temperature envelope

The cells use a non-rechargeable lithium chemistry with a low self-discharge rate and an operating range of -40 to +85°C. They cannot be recharged and are not suited for applications that require a secondary rechargeable cell or a different voltage platform.

Black-plug connector for direct board fit

Each battery terminates in a black plug that matches the 1747-BA footprint used in many backup memory and real-time clock sockets. Verify the pinout and physical dimensions (33.5 x 17mm) against your device before installation.
