The Rayovac Extra Advanced comes with a nickel-clad stainless steel housing to prevent rust and corrosion and a shelf life of up to four years.
The Rayovac Extra Advanced zinc-air hearing aid batteries offer higher power while increasing life. This improves performance in high demand aids used by people who are severely hearing-impaired, including digital and programmable aids.
High drain hearing aids demand greater air flow. Rayovac's "Air Management System", which combines the air cathode, diffusion control element, and vent hole design, provides consistent air flow throughout battery life. This allows the battery to access the precise amount of air needed, maximizing battery power, without compromising performance. The end result is a more consistent, better performing hearing aid battery every time.
