[1] The Curious World of Collective Nouns: A Clutch, A Talent, A Bundle – Exploring the Fascinating Terminology for Battens!

A collective noun for battens would be a "bundle" of battens. Battens are slender strips or rods of various materials, such as wood or metal, commonly used in construction, home improvement, or the sailing industry. As battens are often used collectively or in groups, the term "bundle" aptly captures the nature of how they are typically packaged, transported, or stored together. Similar to the way sticks are gathered in a bundle or set, a bundle of battens refers to a cohesive assembly of these elongated elements. Whether in a construction site, a workshop, or on a ship, the term "bundle" emphasizes the practical and functional aspect of how battens are commonly dealt with and identified as a group.
