Frequently Asked Questions

Following Q&A will teach you everything you wanted to know about batteries and how to optimize the usage.

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.
Empty batteries should always be recycled. You can bring your batteries to a recycling point near you, free of charge.
No. However commonplace they may be, they’re still made up of chemicals that can potentially harm the environment (and the user) if they’re handled incorrectly.
For best performance, always try to keep the battery’s energy level above 30% of its total capacity. Also: always use batteries of the same type and expiry date together.
Panasonic hearing aid batteries are extremely safe. Unless they’re put under extreme circumstances, temperatures or pressure, they provide a very safe power source for your hearing aids.
Zinc air battery are different from other batteries. They do not contain active materials in their positive electrode. This type of battery reacts with air - so it’s important to remove the tag before inserting the battery into your device. They provide a current of 1.4V if used correctly.
No. Condensation could cause damage to your batteries. Avoid putting batteries under extreme temperatures at all times.
Panasonic hearing aid batteries, or zinc air batteries, need air to work. As soon as you pull off the seal, air will flow into the battery, making it able to release energy. Be sure to let the battery breathe for a few minutes before inserting it into your device.
The ideal temperature for our primary batteries is between 5°C up to 45°C.
