Key Specifications

• Battery Chemistry: Lithium
• Voltage: 3.6 VDC
• Application: C300 controller memory backup and RTC retention
• System Compatibility: Honeywell Experion C300
• Mounting: Controller-integrated battery holder

Features & Benefits

1. Non-Volatile Memory Protection: Retains controller firmware, control strategy, and configuration data during extended power outages.
2. Real-Time Clock Retention: Maintains accurate time stamping for alarms, events, and historical data logging.
3. Long Shelf Life: Lithium chemistry provides extended operational life with minimal self-discharge.
4. Hot-Swappable: Battery can be replaced while the controller is powered, eliminating process interruptions.

FAQ

Q: How often should the TC-BATT03 be replaced?
A: Honeywell recommends preventive replacement every 3–5 years depending on ambient temperature and power outage frequency.

Q: What happens if the battery fails?
A: A failed battery triggers a diagnostic alarm. The controller continues operating but will lose memory and RTC data if power is cycled.

Q: Is the TC-BATT03 compatible with C200 or other controllers?
A: The TC-BATT03 is specifically designed for the C300 controller. Verify battery part numbers for other controller families.

Installation Guide

• Locate the battery holder on the C300 controller module.
• Remove the old battery by releasing the retention clip.
• Insert the new TC-BATT03 with correct polarity orientation (match + and – markings).
• Verify the battery status LED or diagnostic message clears after installation.
• Dispose of the old battery per local lithium battery recycling regulations.

Selection Tips

• Stock Rotation: Lithium batteries have a finite shelf life. Rotate stock using first-in-first-out (FIFO) principles.
• Ambient Temperature: High cabinet temperatures accelerate battery degradation. Install the C300 in a climate-controlled enclosure if possible.
• Spare Inventory: Maintain at least one spare TC-BATT03 on-site to enable immediate replacement upon diagnostic alarm.
