Product Information

Rayovac zinc air batteries are environmentally safe. They pass the U.S. Environmental Protection Agency’s toxicity tests for Mercury, Cadmium, and Lead. Rayovac demonstrates its commitment to health and environment in more than one way. In 2008, Rayovac was among the first to protect us from the release of mercury through its introduction of mercury-free hearing aid batteries. Additionally, both the cardboard and the plastic dials of Rayovac battery packages are made from recyclable materials.

With very few exceptions, Rayovac zinc air batteries are made in the USA. Rayovac plants strive to be environmentally friendly through internal EMS systems and quality checks, and its business partners focus on CO2 emissions, pollution prevention, and renewable energy.

Storage loss for all Rayovac zinc-air batteries is at a low rate of 5% per year when stored at 70°F (21°C).

Rayovac cochlear batteries storage loss rate is a low 10% at 70°F (21°C).

To activate and use Rayovac hearing aid batteries and cochlear batteries, remove and discard plastic tab covering air holes. Allow battery to stand for one minute to ensure proper activation. Battery compartment must allow oxygen supply to reach air holes.


Why zinc air technology?

Zinc-air batteries have an especially high energy density and exhibit an almost flat drain curve. They are therefore the ideal power supply, especially for today’s digital hearing aids.

The air holes of the battery are initially sealed with a protective tab. They are kept in this way, in an “inactive state”, until they are needed. The inherent self-drain of zinc air batteries with protective tab attached amounts to a mere 3% a year. The film is removed when the battery is inserted into the hearing aid. After several seconds of activation time, the battery begins to produce current.

In the activated state (with protective tab removed), zinc-air batteries can only be stored for a limited period and should be used as quickly as possible.

After removing the tab, please wait for 5 minutes so that the battery can fully activate and function at peak performance.
