Frequently Asked Questions

Following Q&A will teach you everything you wanted to know about batteries and how to optimize the usage.
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.
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.
Always remove the tab a few minutes prior to installing it into your hearing aid. This allows the battery chemicals to activate.
The results of a voltmeter vary depending on the type of voltmeter used. For a more accurate result, be sure to use a voltmeter with more than 1 megaohm input resistance for alkaline buttons batteries or a 10+ megaohm for lithium batteries.
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.
In appliances without a charging function, yes. In appliances that do have a charging function, be sure to check whether the function was specifically designed for Ni-MH. If not, it’s best not to use Ni-MH batteries.
Battery leakage can be caused by various problems. Read on to learn more.
By recycling your batteries, you actively help reduce landfill waste. Up to 90% of the materials in Panasonic batteries can be reused to make new batteries or processed in other industries.
