Overview
The 3HAC044075 Replacement Battery is an “On Demand” high-performance power solution for ABB industrial robots. It serves as the primary backup for the Serial Measurement Board (SMB), which stores the robot’s axes positions. If your controller displays a “Battery Low” or “SMB Memory Lost” error, this is the exact replacement needed to restore system integrity. Built with premium Lithium-Ion cells, it offers superior energy density and stability compared to standard generic packs.
Key Features
Industrial Reliability: Engineered to withstand the electrical noise and temperature fluctuations of industrial environments.
Plug-and-Play Connector: Comes with the correct 2-pin specialized industrial connector for a direct fit—no soldering or crimping required.
Long Shelf Life: Low self-discharge rate ensures the battery remains ready for years of backup duty.
Data Protection: Prevents the loss of revolution counter data and calibration offsets during scheduled maintenance or unplanned power outages.

Why is this battery essential?
In a production environment, time is money. If the SMB battery fails, the robot forgets its “Home” position. This requires a technician to perform a “Fine Calibration” or “Update Rev Counters”—a process that can take hours. Regularly replacing your 3HAC044075 battery every 2-3 years is the best insurance against line stoppages.
