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.
