Main differences from other similar batteries
The main difference lies in the operating principle of the Pr70 battery. It generates energy through contact with air. Air enters through numerous small holes in the casing and reacts with potassium hydroxide, the electrolyte. This produces energy. The resulting reaction is completely harmless to humans and the environment.
Where is it used?
Due to its safety properties and very small size, it is used for hearing aids, audio and video equipment.
What is prohibited to do with a battery?
The Pr70 battery's performance is affected by its environment. Excessively dry air, especially during the winter heating season, long periods without using the device, and not placing the battery in a drying container can all lead to overdrying and a reduced battery life. Conversely, prolonged exposure to high humidity, which causes the battery to actively absorb moisture and drain quickly, should also be avoided.
As with any battery, avoid sudden temperature changes. Do not store it in the refrigerator, in direct sunlight, or near a radiator. Avoid contact with keys, coins, or any other metal objects, as this can cause a short circuit.

Consumer Advice
When purchasing a Pr70 battery, pay attention to the protective label. It should remain intact throughout use. Having the original blister packaging is crucial, as contact between two unprotected batteries can cause a short circuit.
The small and powerful Pr70 battery opens up new possibilities, allowing the hearing-impaired to communicate with others. Since it makes direct contact with the user, it's important to understand all the features of its use to ensure long-lasting and trouble-free use.
