  • Chemical Composition: Lithium (Non-Rechargeable)

  • Nominal Output: 3.0 Vdc

  • Rated Capacity: 1700 mAh

  • Internal Protection: Integrated safety current limiting to prevent thermal runaway

  • Connector Type: Application-specific polarized connector for secure installation

  • Storage Life: Up to 10 years (at 20°C ambient)

  • Dimensions: 3.4 cm (H) x 1.7 cm (W) x 1.7 cm (D)

  • Net Weight: 0.068 kg

  • Deployment Scope: Honeywell Industrial Automation and Process Control Platforms

Application Maintenance

The TC-BATT01 is typically located within the controller chassis or processor module. To maintain system integrity, engineers should monitor the "Low Battery" diagnostic flag within the controller software. It is recommended to replace these cells during scheduled preventive maintenance cycles to avoid unplanned downtime or memory corruption in the event of a facility-wide power loss.

Frequently Asked Questions

  • Can this battery be replaced while the controller is powered?

    Yes, for most Honeywell systems, replacing the TC-BATT01 while the rack is powered prevents memory loss during the swap. Always refer to your specific controller hardware manual for safety procedures.

  • Is this battery compatible with generic 3V lithium cells?

    While the chemistry may be similar, the TC-BATT01 features a specialized housing and terminal connector tailored to Honeywell hardware specifications to ensure physical fit and electrical reliability.
