Operating rules for hearing aid batteries
We are an authorized importer and distributor of Rayovac hearing aid batteries. The batteries come directly from the manufacturer, ensuring freshness and the highest quality of the batteries sold.
RAYOVAC EXTRA is the most recommended battery for hearing aids. They are considered one of the strongest on the market. They enjoy a very good reputation among users and are praised in discussion groups.
Rayovac zinc-air batteries have very high capacity while maintaining a small battery weight. They withstand high current discharge well. Additionally, they provide very stable output voltage throughout the entire battery life cycle - which is significant for many medical devices.
The batteries have the highest energy density among all mini batteries (3x greater than silver batteries and 5x greater than alkaline batteries). Additionally, the batteries operate correctly in a very wide temperature range: from -10 to 50 degrees C.
The batteries are among the most capacious on the market.
Ideal choice for those looking for the highest quality batteries for their hearing aid.
Each battery is packed in a special protective packaging ensuring tightness - all to ensure that the product reaches the customer as fresh as possible, with full usability characteristics.
| Why choose Rayovac Extra hearing aid batteries? | |
| Excellent compatibility and current efficiency - Rayovac Extra batteries will work in any hearing aid, also functioning with modern hearing implants and speech processors! | |
| High energy density - the most capacious among all button batteries available on the market, up to 5x more energy compared to alkaline cells. | |
| Excellent shelf life - batteries stored in their original packaging remain fully usable for several years! Rayovac Extra batteries can be purchased in bulk, their nominal shelf life is 4 years. | |
| Environmentally friendly - Rayovac Extra batteries do not contain mercury. |
| How to fully appreciate the advantages of zinc-air technology? | |
| After removing the protective sticker, wait at least about 2 minutes before the battery is activated in the device. This time is needed for oxygen to penetrate the battery structures - only then does the battery activate and reach the appropriate voltage for operation. During battery operation, it is also important to ensure that the battery compartment has the ability for further air penetration. | |
| Batteries will last longer if they come from fresh production (long shelf life) and are stored in a dry and cool place (avoid storing batteries in hot places or cold ones, e.g., in the refrigerator - this reduces lifespan). Additionally, it is worth remembering to turn off the device at night and when it will not be used for a long time. It is also recommended to leave the battery compartment in the device open at night - this prevents moisture from settling in it, which adversely affects the batteries. | |
| Avoid: using batteries other than zinc-air (alkaline batteries are significantly weaker and may leak). Avoid keeping discharged batteries in the device or mixing batteries of different brands or mixing new batteries with old ones - always replace the entire set. Do not keep batteries loose with metal objects. | |
| What shortens battery life: higher amplification levels in the device, turning on additional functions, being in noise, prolonged phone conversations (at the ear), high or low humidity, high or low temperatures, air pollution. |
