== Duracell vs. Energizer ==
Duracell and Energizer are two of the most recognizable brands in the disposable battery market. Both companies produce a range of batteries for consumer electronics, though they employ different marketing strategies and have distinct corporate histories. While performance can vary depending on the specific battery type and the device it is used in, both brands are major players in the global battery industry.<ref name="ref1" /><ref name="ref2" /><ref name="ref3" />

The competition between the two brands extends to their marketing mascots. The Duracell Bunny was created in 1973.<ref name="ref4" /><ref name="ref5" /> In 1988, Energizer created a parody of Duracell's advertising, introducing the Energizer Bunny. A 1992 trademark agreement between the two companies resulted in the Energizer Bunny being used exclusively in the United States and Canada, while the Duracell Bunny is used in other parts of the world.<ref name="ref4" />

=== Performance and Technology ===
Both Duracell and Energizer primarily produce alkaline batteries for general consumer use. Duracell's Duralock technology and Energizer's PowerSeal technology are both marketed with the claim of allowing batteries to retain power for up to a decade in storage.

Performance tests comparing the two brands have yielded mixed results that often depend on the specific device being powered. Some tests have indicated that Duracell batteries may last longer in high-drain devices, while Energizer's lithium offerings are also recognized for their strong performance in similar applications. For low-drain devices, the performance difference between the two brands' alkaline batteries is often less pronounced.

Both companies offer lines of batteries intended for industrial and professional use, with Duracell's Procell and Energizer's Industrial brands being functionally similar to their consumer counterparts but sold in larger quantities.

=== Corporate Structure and Market Share ===
Duracell has been a wholly-owned subsidiary of Berkshire Hathaway since 2016. The company's origins trace back to the 1920s with the work of Samuel Ruben and Philip Mallory. Energizer Holdings became an independent company in 2000 after being spun off from Ralston Purina.<ref name="ref3" /> Both companies hold significant shares of the global battery market.<ref name="ref1" /><ref name="ref2" />
