Industrial Backup Power

This pack supplies eight 3V lithium cells rated at 1800mAh each, built for PLCs, CNC controllers, servo drives and similar industrial equipment that rely on non-rechargeable backup power. The black connector matches the 1747-BA form factor used in many legacy automation panels.

Connector and Mounting

Each cell measures 33.5 by 17mm and terminates in a black plug designed for direct board insertion, so installation requires no soldering or adapter cables. The wide operating range from -40 to +85 Celsius lets the batteries stay reliable inside cabinets that see extreme ambient temperatures.

Capacity Decides Fit

At 1800mAh the CR14250SE delivers the energy density needed for long-term memory and real-time-clock retention in programmable logic controllers and measuring instruments. Buyers who need a rechargeable chemistry or a higher-capacity cell for extended outage riding will need a different product.
