Frequently Asked Questions

Following Q&A will teach you everything you wanted to know about batteries and how to optimize the usage.
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.
This is a vibration noise which occurs when electric current flows through a transformer or a winding wire inside a component part. However, the charger may still be used without any concern as there is no need to worry from a safety point of view.
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.
Batteries are classified according to IEC classification standards: LR03 is equal to AAA, but in another standard.
It’s possible, yes. But we can never guarantee perfect functionality - so we recommend charging your Panasonic batteries with a Panasonic or eneloop charger.
You’re always allowed to board the plane with your hearing aid batteries in the device. For regulations on bringing spare hearing aid batteries, please consider contacting your airline.
The capacity of batteries is indicated as XXXX mAh (milliampere/hour). If you insert this battery into an appliance which consumes 100 milliampere current continuously, the operating time of the appliance will be around 20 hours mathematically.
In case of skin contact there is a chance of chemical burns. Use clear tepid water for at least 15 minutes on exposed skin. Consult a physician in case of irritation, injury or pain. In case of contact with the eye, do not rub the eyes, but flush with clear tepid water for at least 30 minutes and consult a medical professional immediately.
As new energy flows into your battery, some heat is perfectly fine. If you notice the battery or charger becomes too hot to touch, cease the charging process immediately.
