Megger Torkel 910 Battery Load Tester
- Perfect for professionals responsible for maintaining a reliable power system
The Megger Torkel 910 is a powerful battery load tester. It helps make sure your important power systems work when you need them. The Torkel 900 series from Megger is a reliable tool. This advanced battery load unit helps you measure the real capacity of your batteries. It does this through controlled discharge testing, and you do not need to disconnect them from service.
The Torkel 910 is made for tough jobs like high voltage substations, factories, and backup power systems. It offers precision, safety, and ease of use. The ideal choice for engineers and technicians who need reliable results in substations and industrial environments.
Battery systems are a critical safety net for electrical grids, industrial plants, telecommunications, and emergency backup systems. Over time, all batteries lose capacity – and without accurate testing, they can fail when needed most. The Megger Torkel 910 helps prevent this by delivering accurate, real-world performance checks that simulate operational loads. Testing under real working conditions gives you confidence that your batteries will work during outages, emergencies, or maintenance.
The Torkel 910 is different from simpler testers. It uses dynamic discharge technology. This keeps the current or power steady, even when the voltage drops.
This ensures your test data is accurate, reliable, and directly comparable over time. And because it allows in-service testing, there’s no need for system shutdowns, saving both time and cost.

Key Features & Benefits:
