Frequently Asked Questions

Following Q&A will teach you everything you wanted to know about batteries and how to optimize the usage.
When inserting a battery, make sure you do the following: insert it the correct way, with plus and minus poles touching the right terminals; use the right coin battery size; avoid dirt or any other substances obstructing proper contact; carefully insert it, not putting stress on it as you’re closing up the holder. Makes sure it makes contact with the terminals.
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.
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.
Always remove the tab a few minutes prior to installing it into your hearing aid. This allows the battery chemicals to activate.
Coin batteries have a low voltage (1.5 V) and a diameter less than 12 mm to prevent any serious accident. Also, packaging has been designed specifically to prevent accidental ingestion. Panasonic coin batteries are thus relatively safe and serious accidents are very uncommon.
Battery lifespan greatly depends on the device and on the conditions.

Whereas some size change is perfectly normal, it should not be overly pronounced. If so, replace the battery immediately. A bulging coin battery may lead to device malfunction and even short-circuiting.
Polarity reversal may happen when more than two batteries are connected in series and used until the last moment of discharge.
