Which Energizer advertising character became famous for continuing to move while rival batteries stopped?

The Energizer Bunny is the advertising character shown continuing to march while other batteries run out of power.

Energizer introduced the pink rabbit in 1988. The character played drums and wore sunglasses, creating a visual demonstration of long-lasting battery life. The campaign’s central joke was that the rabbit kept going and going, a phrase that became closely associated with Energizer.

The idea followed a legal and marketing dispute involving Duracell, which had used a pink toy rabbit in advertising in some markets. Energizer’s version became the better-known American character, while Duracell continued using its own bunny in other advertising territories.

The Energizer Bunny is therefore not simply a generic symbol for batteries. It is a specific mascot whose identity developed from competing campaigns and trademark practices. Its continuing-motion image remains one of the most recognizable examples of comparative advertising.
