BETHEL, Conn. — Duracell has launched an advanced alkaline battery with long-lasting power, a product it's calling the "biggest innovation since CopperTop." The new Duracell Quantum was engineered from the ground up to offer consumers a premium alkaline battery. Available in AA and AAA cell sizes, Duracell Quantum features a revolutionary Hi-Density Core, which allows the Duracell Quantum battery to pack in more power than ever before.
The new battery also is the only one on the market with PowerCheck, which is a power indicator on the cell, as well as Duralock Power Preserve technology, which preserves power for up to 10 years in storage. Duracell Quantum is engineered to work efficiently across all battery-operated devices in a household, whether it is low-drain (e.g., remote controls or clocks} or high-drain (e.g., camera flash or gaming controls).
