GE BS-49074 R104 Battery Load Unit – Complete Product Overview

GE BS-49074 R104 is a professional battery discharge load unit designed for use with the TORKEL 840 battery testing system from General Electric (Programma / Megger heritage). It is widely used by utilities and industrial facilities to verify the real capacity and reliability of critical backup battery systems.

This unit plays a key role in preventive maintenance programs where battery failure is not an option.

What is GE BS-49074 R104?

The BS-49074 R104 is an external load module (load bank) that works together with the TORKEL 840 battery discharge tester. It provides additional discharge capacity, allowing engineers to test medium and large battery banks safely and accurately.

Product Category

• Battery discharge testing equipment
• Utility battery load bank module
• Industrial maintenance & commissioning tool

Why Battery Discharge Testing Is Critical

Backup batteries power essential systems during outages, including:

• Electrical substations
• Power plants
• UPS and data centers
• Telecommunications networks
