Which of the following are considered ongoing consumable products?

Ongoing consumable products are items that are frequently used and require regular replacement as part of the operations and maintenance of a facility. Batteries qualify as ongoing consumable products because they are utilized in a wide range of applications, from remote controls to emergency lighting systems, and typically have a limited lifespan after which they must be replaced.

Notebooks, while used regularly, do not require continuous replacement in the same way, as they are not a necessity for operations unless a specific need arises. Computers serve a longer shelf life and can often be repaired or upgraded, rather than being routinely replaced as an ongoing consumable. Light bulbs are indeed consumable products, but they typically have a longer life span compared to batteries and may not be considered "ongoing" in the same context, as they are replaced less frequently depending on usage patterns. Therefore, the characterization of batteries aligns best with the definition of ongoing consumable products in this context.
