Industrial backup power

This pack contains five TOPMAO CR14250SE lithium cells rated at 3 V and 1800 mAh each. They are built as direct replacements for 1/2 AA PLC backup modules such as the 1747-BA used in programmable logic controllers and CNC equipment.

Thermal behaviour and power

The chemistry operates across a wide temperature span from minus 40 to plus 85 °C with a low self-discharge rate. As non-rechargeable primary cells they draw no charging current and generate no heat during normal backup duty.

Decisive specification

The 1800 mAh capacity at 3 V determines how long memory and real-time clocks stay powered during mains loss. Buyers needing a rechargeable cell or a different voltage must choose another product.

Questions about this item

How do I install the CR14250SE battery in a PLC and which step is commonly missed?

Insert the battery with the black plug aligned to the keyed header, then secure the retaining clip; the step often missed is verifying the plug orientation before applying force.

What maintenance or replacement will the 1800mAh lithium cell need over time?

As a non-rechargeable lithium battery, it requires no maintenance; replace the cell when the backup memory or real-time clock loses data after power-off.

At what temperature limit does the CR14250SE show reduced performance during sustained operation?

The specified operating range is -40 to +85 °C; sustained use near the upper limit accelerates self-discharge and shortens usable life.
