Battery Rack is defined as?

• A. A module consisting of a number of cells.
• B. A device used to vertically store battery modules.
• C. An alarm signal receiver.
• D. An approved device.

Answer: (B)

A battery rack is the device used to vertically store battery modules. This structure organizes multiple battery modules in a vertical arrangement, saving space and making it easier to handle and service the batteries in areas like refrigeration systems with flammable refrigerants. It’s not the batteries themselves (modules or cells), nor an alarm receiver, nor just any generic approved device—the rack’s purpose is specifically to hold and organize the battery modules in a vertical storage setup.
