The origin of the energizer bunny
Frequently Asked Questions
This "parallel universe" of branding is the result of a major trademark oversight by Duracell in the 1980s. While Duracell created the original drumming bunny in 1973, they failed to renew their exclusive trademark rights for the character in the United States. Energizer’s parent company, Eveready, seized this opportunity to launch their own version of the bunny in 1989. Because Duracell maintained their trademarks in other regions like Europe, Australia, and Asia, they still own the mascot there, while Energizer holds the rights in the U.S. and Canada.
Energizer pulled off what is described as a "marketing heist" by using parody. Instead of just copying the cute, toy-like nature of the original Duracell bunny, Energizer created a "rebellious" version with sunglasses, flip-flops, and a bass drum. They launched ads where their bunny would "interrupt" and march through the sets of other fake commercials. This aggressive and humorous approach sowed enough confusion that the American public eventually forgot the mascot was ever associated with Duracell, effectively erasing the original from the country's collective memory.
While both are high-quality batteries, they are often optimized for different "missions." Technical tests suggest that Duracell batteries tend to excel in longevity and steady energy flow, making them ideal for low-drain devices like smoke detectors or remote controls. In contrast, Energizer batteries are often seen as "sprinters" that perform better in high-drain devices that require powerful surges of energy, such as digital cameras with flashes or motorized toys.
The legality of using the bunny depends on whether the use is considered a "legitimate parody." In the case of Eveready Battery Company v. Adolph Coors, a court ruled that a Coors Light commercial featuring actor Leslie Nielsen in a bunny suit was protected as "fair use." The court found that because beer and batteries are dissimilar products, there was no risk of consumer confusion. A successful parody is legally protected if it imitates the original for humor but remains distinct enough that it doesn't "usurp the market" or steal customers from the original brand.
