From Emerson Network Power / Liebert Power & Cooling
 

 

In a critical power application, stationary batteries should be properly installed, inspected, commissioned and tested before being placed into full service. Unfortunately, some installers hurry through inspections and the load test is performed before the batteries are properly prepared. This paper outlines the correct way to prepare batteries for load test and explains the importance of each step.
