Product Overview

The TC-BATT03 (Part Number 51199942-300) is an authoritative lithium-ion backup battery assembly specifically engineered for the Honeywell C300 Controller and Experion PKS environments. This module is a mechanical necessity for ensuring data integrity during primary power interruptions. By providing a 2200mAh reserve at 3.6V, the TC-BATT03 allows the controller to perform an orderly memory save and shutdown, preventing the loss of critical process configurations. Built for the rigorous demands of refineries and chemical processing facilities, this battery unit is a trustworthy component for maintaining high system availability and meeting industrial safety standards.

Detailed Technical Specifications

Engineering and Installation Guide

• Module Integration: The TC-BATT03 connects directly to the C300 controller or its designated power system. Ensure the connector is fully locked; a loose connection is a common point of failure for backup systems.

• Battery Life Management: Lithium-based cells like the 51199942-300 are sensitive to high temperatures. Installing controllers in climate-controlled cabinets is a recommended expertise to maximize the 3–5 year service life.

• Replacement Protocol: When the Experion system reports a "Low Battery" alarm, the TC-BATT03 should be replaced immediately. Replacing the battery while the system is powered (Hot-swap) is generally supported to avoid data loss, provided the primary power is stable.

• Disposal Compliance: As this contains lithium, disposal must follow authoritative environmental regulations for hazardous industrial waste. Do not incinerate or puncture the casing.

Technical FAQ

What is the difference between TC-BATT01 and TC-BATT03?

The TC-BATT03 (2200mAh) offers a higher capacity and is specifically optimized for the higher power requirements of the C300 controller series compared to the older TC-BATT01 models used in legacy power assemblies.

How long will the battery hold the controller memory?

The 51199942-300 typically supports the controller for several minutes of active operation to allow for a switchover to a redundant controller or to save volatile RAM data to non-volatile flash memory during a total power loss.

Does the battery come pre-charged?

Batteries are usually shipped at a partial charge state for safety. Once installed, the C300 system's internal charging circuit will bring the TC-BATT03 to full capacity within a few hours of operation.
