Cascade Highlands — Young Vancouver students gathered for Earth Day on April 22 at the Mill Plain Boulevard Whole Foods Market to learn about recycling and check out a new battery exchange kiosk. The Bettery Inc. “Swap Station,” one of five recently unveiled at Whole Foods stores in Oregon and Washington, lets customers exchange spent reusable batteries for fully charged ones. The Portland startup’s kiosks operate on a similar business model to Redbox, providing on-demand access to reusable batteries at a potentially lower cost than disposable batteries.
