ABB 3HAC16831-1 – 10.8V Lithium Backup Battery Pack | IRC5 Robot Controller Platform
Engineering Background: The ABB 3HAC16831-1 is the current-generation lithium battery pack designed to maintain SRAM memory, real-time clock, and system parameter retention in ABB IRC5 robot controllers during power-off states. It supersedes the earlier 3HAC13150-1 NiMH battery and delivers significantly improved cycle life, lower self-discharge, and stable voltage output across a wider temperature range — critical for 24/7 manufacturing environments.
Product Positioning: Sourced directly from verified ABB-authorized supply chains, the 3HAC16831-1 is the preferred choice for maintenance engineers performing scheduled battery replacement on IRC5 single-cabinet and dual-cabinet controllers. Konmask.com stocks genuine and OEM-equivalent units with full traceability documentation available on request.

Proven Application Environments
- Automotive Body Welding Lines — IRC5 controllers managing spot-welding robots requiring uninterrupted memory backup during shift changeovers and planned shutdowns.
- Electronics Assembly & SMT Lines — High-uptime environments where controller reboot from memory loss causes costly re-teaching cycles.
- Palletizing & Material Handling — Warehouse automation with frequent power cycling; lithium chemistry ensures reliable cold-start backup.
- Painting & Coating Booths — Explosion-proof IRC5 variants (IRC5P) also use this battery for program retention.
- Preventive Maintenance Programs — OEM-recommended replacement interval: every 3–5 years or upon low-battery alarm (event log code 38213).
Engineering Advantages
- Direct Drop-In Replacement for 3HAC13150-1: Same form factor, connector, and voltage profile — no firmware changes or hardware modifications required.
- 3× Longer Service Life vs. NiMH: Li-Ion chemistry eliminates memory effect and delivers consistent capacity over 500+ charge cycles.
- Low Self-Discharge: Retains >80% charge after 12 months of shelf storage — ideal for spare-parts inventory management.
- Wide Temperature Tolerance: Stable performance in both climate-controlled and non-air-conditioned factory environments.
- Plug-and-Play Installation: No calibration required post-installation; IRC5 controller auto-detects battery presence on next power-up.
System Architecture & Signal Flow
Within the IRC5 controller cabinet, the 3HAC16831-1 battery connects to the Main Computer Unit (MCU / DSQC 639) via the battery interface board. Its primary functions are:
- SRAM Backup: Preserves robot programs, tool data, work object definitions, and I/O configurations during power loss.
- RTC (Real-Time Clock) Power: Maintains system timestamp for event logging and scheduled task execution.
- Alarm Trigger: When voltage drops below threshold (~9.6 V), the controller generates event log warning 38213 – Battery charge low, prompting scheduled replacement.
Compatible controller variants: IRC5 Single Cabinet (M2004–M2016), IRC5 Dual Cabinet, IRC5 Panel Mounted Controller (PMC), IRC5 Compact.
Sourcing & Quality Verification
- Traceability: Each unit ships with batch number and production date code; documentation available on request for ISO-audited facilities.
- Pre-Shipment Testing: Open-circuit voltage ≥ 10.5 V verified before dispatch; capacity spot-check available for bulk orders.
- Packaging: Anti-static bag + foam-lined carton; UN3480 lithium battery shipping compliance (air freight available with MSDS/SDS).
- Lead Time: In-stock units ship within 1–3 business days; bulk orders (10+ units) contact for priority allocation.
Procurement Process
- Confirm your IRC5 controller serial number and current battery part number (label on existing battery or controller door).
- Add ABB 3HAC16831-1 to cart or contact [email protected] for a formal quotation with HS code documentation.
- Select shipping method — DHL Express (3–5 days worldwide) or sea freight for bulk orders.
- Receive unit, verify OCV with multimeter before installation, replace per ABB Product Manual 3HAC021313-001.
Technical FAQ
Q: Is 3HAC16831-1 a direct replacement for 3HAC13150-1?
A: Yes. ABB officially superseded 3HAC13150-1 with 3HAC16831-1. The new part uses Li-Ion chemistry instead of NiMH, with identical connector and mounting — no hardware modification needed.
Q: How do I know when to replace the battery?
A: The IRC5 controller generates event log code 38213 – Battery charge low. ABB also recommends proactive replacement every 3–5 years as part of scheduled maintenance.
Q: Can I ship this battery by air freight?
A: Yes, with proper IATA PI 965/966 documentation. Konmask provides MSDS/SDS and UN3480 labeling for all lithium battery shipments.
Q: What happens if the battery fails completely?
A: The IRC5 controller will lose all stored programs, tool data, and configurations on next power cycle. A full system restore from backup is required — making proactive replacement critical.
Q: Do you offer volume pricing for MRO contracts?
A: Yes. Contact [email protected] for annual MRO pricing, consignment stock arrangements, and blanket PO terms.
