Frequently Asked Questions

Following Q&A will teach you everything you wanted to know about batteries and how to optimize the usage.
Never charge Ni-MH batteries with a Ni-Cd charger. There are significant differences in charging conditions between those two types of batteries.
Panasonic EVOLTA NEO is your best choice for high-drain devices. Thanks to more precise manufacturing, increased density and silver compounds, the battery will greatly outperform other batteries.
All batteries, including Panasonic hearing aid batteries, can and should be recycled.
At this point Panasonic does not produce AAAA or LR61 batteries.
They do. We guarantuee performance for up to three years after production. After this we cannot guarantee the battery will perform as well as it’s supposed to.
For best performance, always try to keep the battery’s energy level above 30% of its total capacity. Also: always use batteries of the same type and expiry date together.
In general it’s best to never let your batteries deplete completely. Try to recharge them before the energy level drops below 30%.
No. However commonplace they may be, they’re still made up of chemicals that can potentially harm the environment (and the user) if they’re handled incorrectly.
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.
Because there is a slight difference between manufacturers. Always use the previously used type of batteries which did fit in the compartment in case the batteries do not fit.
