Duracell Promotional LEGO Sets

LEGO collaborated with Duracell to release promotional sets in the late 1990s and early 2000s. These were often small polybag sets or exclusive builds that were included with Duracell battery packs as a bonus item. Examples include miniature vehicles or figures that tied into popular LEGO themes of the time. These sets were typically used as marketing tools to promote both Duracell batteries and LEGO products, creating a mutually beneficial brand partnership.
