Rechargeable Hearing Aid Batteries Draw from NASA Research

A real-world story of NASA technology finding a life beyond the mission.

About this technology

Overview

Research In its early days, NASA spent much effort developing rechargeable silver-zinc batteries, as the pairing offers a higher power-to-weight ratio than any other battery couple. Significant advances in the batteries_ durability were made at Glenn Research Center, which ZPower of Camarillo, California, used as part of its starting point, undertaking years of additional development before releasing its rechargeable hearing aid batteries, the first that can last all day on a single charge.
