Description
The FBT030A replacement battery is designed for compatible Fuji Electric MICREX-F programmable logic controllers that require the FBT030A backup battery configuration.
This aftermarket battery assembly includes a cylindrical lithium cell, red-and-black connecting wires and a four-position connector. In addition, its compact format makes it suitable for equipment designed to accommodate the corresponding backup battery.
Many compatible FBT030A replacements use a 3.6V, 1200mAh lithium cell. However, the actual capacity and battery chemistry of the supplied replacement must be verified against its technical specifications.

Compatible Fuji Electric PLC Systems
The FBT030A battery reference is associated with Fuji Electric MICREX-F industrial controllers.
Replacement battery catalogues identify compatible configurations for selected MICREX-F models, including:
- MICREX-F55
- MICREX-F70
- MICREX-F140S
- MICREX-F150S
However, controller compatibility can depend on the equipment version and battery connector arrangement.
Therefore, verify the original battery model and consult your equipment manual before purchasing.
Why Do Industrial PLCs Need Backup Batteries?
Certain programmable logic controllers use batteries to retain designated memory contents when the main power supply becomes unavailable.
For example, battery-backed controller memory may preserve stored information during a temporary interruption.
Furthermore, regular battery inspection helps identify potential backup-power problems before they cause data loss.
Nevertheless, the specific battery function and replacement procedure depend on the controller design.
Original Fuji Electric FBT030A vs Compatible Replacement
Original Fuji Electric FBT030A
- Manufacturer-specified backup battery reference
- Intended for supported MICREX-F applications
- Uses the original equipment battery specification
Compatible FBT030A Replacement
- Manufactured or assembled by a third-party supplier
- Intended to replace the FBT030A battery configuration
- Must match the necessary voltage and battery chemistry
- Must have the correct connector arrangement and polarity
- Not manufactured or endorsed by Fuji Electric
This ArcEin product is the compatible replacement version.
Connector and Polarity Compatibility
The supplied battery features a wired four-position connector.
However, other FBT030A replacements may use different connectors. For this reason, connector appearance alone does not guarantee compatibility.
Before installation, compare the replacement’s wire positions, terminal connections and electrical polarity with the approved original battery.
Incorrect polarity or wiring may damage industrial equipment.
Installation and Replacement Guidance
- Identify the complete PLC controller model.
- Confirm that the equipment requires an FBT030A battery.
- Check the battery voltage and chemistry requirements.
- Compare the connector and wiring with the original assembly.
- Review the manufacturer’s maintenance procedure.
- Follow the necessary precautions to protect retained data.
- Install the replacement as instructed by the equipment manual.
- Check the controller’s battery-status indication.
Important: Incorrect battery replacement can result in retained-data loss or equipment downtime. Qualified industrial maintenance personnel should perform this work.
Battery Storage and Handling
Store the replacement battery in a suitable cool, dry environment.
Additionally, protect the connector terminals from conductive objects to prevent accidental short circuits.
Before installation, inspect the cell wrapping, wires and connector for physical damage.
Do not use a leaking, swollen or visibly deteriorated battery.
Important Battery Safety Instructions
- Never recharge this primary lithium battery.
- Do not short-circuit the connector terminals.
- Avoid crushing, puncturing or dismantling the cell.
- Keep away from heat and fire.
- Never reverse connector polarity.
- Do not install damaged batteries.
- Store securely away from children.
- Dispose of used batteries according to applicable regulations.
