Panasonic hearing aid batteries, or zinc air batteries, react with air. As soon as you pull off the seal, the battery will be able to release energy. Be sure to let the battery breathe for a few minutes before inserting it into your device.

You can, but they’ll perform best in medium- to high-drain devices.

While most batteries will still work in extreme temperatures (albeit with shorter lifespans), Panasonic EVOLTA NEO is your best choice for extreme cold or warm weather.

Polarity reversal may happen when more than two batteries are connected in series and used until the last moment of discharge.

Once a seal is peeled off, the battery starts ‘breathing’ and therefore gives of energy, even if it’s not used in a hearing aid. The battery therefore won’t last until the expiry date if the seal is removed.

Immediately head to the nearest emergency room. Avoid drinking or eating before a doctor has provided a decent diagnosis.

Panasonic zinc air batteries have been specifically designed for hearing aids, other batteries may not perform as well.

Battery lifespan greatly depends on the device and on the conditions.

Replace your battery as soon as your hearing aid no longer functions properly. If this happens unusually soon, consider checking if contact between the battery and the terminals inside is faulty.
