“Energizer is always innovating to meet the needs of manufacturers and consumers alike,” said Jeff Ziminski, Chief Marketing Officer. “As devices continue to get smaller and smaller, we see a greater need and relevance for the Energizer AAAA.” Energizer has been actively partnering with original equipment manufacturer (OEM) companies to help them design around the AAAA battery. Recently, GN, the world leader in innovative headset solutions, launched the AAAA battery-powered Bluetooth headset.

The AAAA is 42.5 mm long and 8.3 mm in diameter and weighs approximately 6.5 grams. This means that the AAAA batteries weigh 43 percent less, are 40 percent smaller in volume, and are 20 percent thinner than the standard AAA. The Quad A is currently used in flash audio players, Bluetooth headsets, laser pointers and LED penlights, remote controls, and home medical devices, like glucose meters and blood pressure monitors.
