Frequently Asked Questions

Following Q&A will teach you everything you wanted to know about batteries and how to optimize the usage.
No. Do not use batteries in water or in vacuum conditions - this will cause them to rust and short-circuit.
Use batteries for their right purpose: insert them correctly, replace them when empty and store them dry and at room temperature.
Panasonic hearing aid batteries, or zinc air batteries, react with air. As soon as you pull off the seal, the battery will be able to release energy. Be sure to let the battery breathe for a few minutes before inserting it into your device.
Never use Ni-MH rechargeable batteries for waterproof appliances, appliances specifically designed for alkaline batteries, or in appliances with battery indicators.
Panasonic strongly advocates not attempting to charge primary batteries such as alkaline, zinc carbon, or lithium, using Ni-MH chargers. Alkaline batteries are not designed for recharging, and doing so could cause leakage and in the worst case lead to the batteries exploding.
Cycle life is the number of times the rechargeable battery can be recharged.
Batteries are best stored at room temperature. Extreme heat or cold can significantly reduce battery life.
Operating times may vary depending on the conditions in which you use your hearing aid. The most common cause is not letting it breathe after you take off the seal. Ensure at least 60 seconds of air flow before inserting it into the hearing aid.
Mixed use or leaving the battery in the appliance can cause battery leakage.
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.
