Battery Module is defined as?

• A. A module consisting of a number of cells generally connected in either series or parallel.
• B. A device used to vertically store battery modules.
• C. An alarm receiver.
• D. An approved piece of equipment.

Answer: (A)

A battery module is defined as a unit that contains multiple cells grouped together to achieve a specific voltage and capacity, typically connected in series to raise voltage or in parallel to increase current/amp-hour capacity. This grouping provides a practical, interchangeable building block for larger battery systems, making assembly, testing, and maintenance more manageable.

The other options describe uses or roles rather than what a battery module is: a device for vertically storing modules is about physical storage, an alarm receiver is unrelated to battery construction, and an approved piece of equipment is a status or designation, not the structural definition of a module.
