Frequently Asked Questions

Following Q&A will teach you everything you wanted to know about batteries and how to optimize the usage.
You can, but they’ll perform best in medium- to high-drain devices.
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.
The revised RoHS (Reduction of Hazardous Substances) Directive 2011/65/EU...
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.

Battery leakage can be caused by various problems. Read on to learn more.
Change the batteries as soon as the device starts malfunctioning. Remove the batteries if you plan on not using the device for a longer period of time.
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.
As zinc air hearing aid batteries operate differently than other batteries they have different characteristics. In winter, rooms may be drier, warmer or badly ventilated. These effects can disturb the performance of your batteries.
Batteries are chemical products which internally undergo certain chemical processes over time. Due to this process some batteries slightly discharge during storage.
