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.
While leakage is rare, it may still occur if the battery is used incorrectly. Leakage is usually caused by leaving the battery in an unused device or short-circuiting.

You can, but they’ll perform best in medium- to high-drain devices.
Please seek medical attention immediately. While serious accidents are relatively uncommon, swallowing a coin battery may still cause burns or breathing difficulties.

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.
There can be several reasons why the appliance doesn't work. The battery can be wrongly inserted in the battery compartment, there can be a bad connection between the battery and the compartment connection terminal or it is possible the appliance does not work properly.
There are different types of Panasonic alkaline batteries, each with their own specialty.
Battery lifespan greatly depends on the device and on the conditions.
