📄 Description

The ABB 3HAC6157-1 is a genuine lithium backup battery pack designed to preserve critical robot data—including calibration parameters, zero position references, motion programs, and system configurations—in ABB’s IRC5 and OmniCore robot controllers during main power interruptions.

Unlike standard PLC batteries, this unit powers the absolute encoder memory circuits in ABB robots. If the battery fails or is removed without replacement, the robot loses its “home” reference, requiring time-consuming and costly manual recalibration (often involving laser trackers and downtime of 8–24 hours).

The 3HAC6157-1 delivers 4.8 V DC at 2.4 Ah using high-reliability lithium cells, offering up to 3 years of service life under normal operating conditions. It features a robust connector and snap-in mounting for quick field replacement—no tools required.

⚠️ Critical Application Scenario

At an automotive body shop in Michigan, a scheduled weekend power shutdown caused multiple ABB IRB 6700 robots to lose calibration due to expired backup batteries. The production restart was delayed by 36 hours while metrology teams re-established zero positions—costing over $ 1.2 million in lost output. After implementing a proactive 3HAC6157-1 battery replacement program (every 24 months), the plant eliminated repeat incidents. In this context, the 3HAC6157-1 wasn’t just a battery—it was a $ 1M+ insurance policy against unplanned downtime.

⚙️ Key Specifications

表格

❗ Warning: Never remove the old battery before installing the new one unless using an external backup power source (e.g., ABB’s 3HAC028412-001 temporary battery). Otherwise, data loss is immediate.

💡 Why This Battery Matters

Preserves Absolute Calibration: ABB robots use absolute encoders that retain position only as long as backup power is present. No battery = no reference = full recalibration.

Avoids Production Disruption: Recalibrating a single robot can take 4–12 hours and require specialized technicians.

Ensures Traceability & Quality: In regulated industries (aerospace, pharma), losing calibration invalidates process validation.

Plug-and-Play Reliability: Genuine ABB design ensures correct voltage regulation and connector integrity—unlike generic substitutes that may leak or underperform.
