Duracell Optimum
Driving Innovation in a Sleepy Category
The Challenge
As the number one trusted battery brand, Duracell introduced a first-of-its-kind alkaline battery with a new cathode system: the Duracell Optimum. The technology was disruptive and the packaging needed to match. Consumer research surfaced two persistent pain points: batteries were constantly lost in junk drawers, and retailers struggled to optimize the category at shelf. Duracell called on Kaleidoscope to design packaging as innovative as the product inside.
Our Approach
Kaleidoscope began with broad store auditing across mass and convenience retailers to understand the battery environment firsthand. That informed a collaborative innovation workshop with real-time prototyping, grouping concepts by sustainability, user experience, and production feasibility. From there, we repeatedly prototyped and tested for hanging, standing, and durability, while incorporating continuous consumer feedback on usability and ergonomics down to how the pack feels in hand.
The Impact
The resulting Duracell Optimum packaging was a sleek, resealable box that solved for at-home storage and enabled dramatic brand blocking at retail. The launch delivered measurable results, including an 8% increase in earnings. Proof that their pursuit of innovation never loses power.
