30-Pack Industrial Lithium Cells

This pack supplies thirty TOPMAO CR14250SE lithium batteries rated at 3 V and 1800 mAh each. They are built for industrial equipment such as PLCs, CNC machines, servo drives and backup memory circuits that require a 1/2 AA form factor. The cells are non-rechargeable and intended for maintenance engineers and automation technicians who need reliable long-term power in critical devices.

Installation and Common Issues

Each cell includes a black plug connector that mates directly with the target equipment, so no soldering is required. Installation is a simple plug-in replacement, but the battery must be inserted with the correct polarity marked on the housing. The most frequent problem is fitting a cell into a compartment designed for a different diameter; the 33.5 mm length and 17 mm diameter must match the original 1747-BA specification.

1800 mAh Capacity Decides Suitability

The 1800 mAh capacity determines how long the battery can sustain backup power before replacement. If the application demands a higher capacity or a rechargeable chemistry, this pack will not meet the requirement. Buyers who need more stored energy or a different voltage should look for an alternative specification.

Questions about this item

How can I confirm the CR14250SE is delivering the rated 3V after installation?

Measure the open-circuit voltage with a multimeter; a fresh cell should read at or very close to 3V, indicating it is ready for PLC backup or CNC memory duties.

What exactly comes in the 30-pack and do I need any extra connectors?

The package contains 30 lithium CR14250SE cells, each fitted with a black plug; no additional connectors or cables are included.

Which capacity version should I choose for a 1747-BA backup supply?

This listing provides the 1800mAh model, which matches the spec for 1747-BA backup power applications.
