DUSLAN LS14250-MR 3.6V Lithium Cell

The DUSLAN LS14250-MR is a 3.6 volt lithium primary cell rated at 1200 mAh. It serves as a direct replacement for Fuji and Mitsubishi PLC backup modules such as the FBT020A, FBT030A, Micrex-F, Micrex-SX and NB8P-BT series. Engineers maintaining legacy automation panels or Toyo Denki GPCs systems will find the electrical match exact. The cell uses wire leads with a connector for straightforward board-level installation.

Wide Temperature Range and Low Self-Discharge

Lithium chemistry allows operation from minus 60 °C to plus 85 °C without performance loss. The cell draws no load current until the PLC demands backup power, so heat generation and audible noise are absent in normal service. Its low self-discharge rate supports multi-year data retention in memory and real-time clock circuits. The 15 mm diameter by 26 mm length fits the original battery compartment without modification.

Drop-In Compatibility Across Vendor Parts

The bundled connector matches the pin-out used by Fuji Electric FBT020A, FBT030A and Mitsubishi ER3V-C, ER3V 3.6V, C52005 modules. Energy+ LS14250-MR cross-reference confirms the same form factor. No firmware update, adapter cable or mounting hardware is required; the installer simply plugs the lead into the existing socket. This reduces downtime during scheduled battery refresh cycles.

Questions about this item

How do I install the LS14250-MR FBT020A with its wire leads and connector into a PLC, and what step do people get wrong?

Match the connector polarity to the board header, press firmly until it clicks, and secure the 15mm diameter cell in its holder; the step often missed is verifying the keyed orientation before forcing the plug.

What maintenance or replacement will the 3.6V 1200mAh lithium cell need later?

The primary lithium chemistry is non-rechargeable, so plan a single replacement when the PLC clock or memory backup fails; no periodic charging or cycling is required.

What limit appears first when the battery runs continuously at the upper end of its -60c to +85c range?

Elevated temperature accelerates self-discharge, so capacity drops faster at +85c, shortening the useful backup life before the 1200mAh rating is exhausted.
