Energizer Ultimate Lithium AA battery

Energizer is one of the world's most recognizable brands in the portable power industry. The story of the brand dates back to the late 19th century with the founding of the Eveready Battery Company. Over the decades, the brand evolved, eventually splitting from Ralston Purina and becoming a standalone entity.

The Energizer Ultimate Lithium line, shown in the image, represents the premium tier of their battery offerings. It is widely known for being long-lasting and effective in extreme temperatures. While Energizer operates various facilities globally, their high-performance lithium batteries are historically and primarily manufactured in specialized facilities in Singapore to meet global demand.

Today, the brand is owned and operated by Energizer Holdings, Inc., a major American consumer goods company. Headquartered in St. Louis, Missouri, the company manages a diverse portfolio of battery, portable lighting, and automotive fragrance and appearance brands.
