Batteries come directly from the manufacturer, guaranteeing freshness and the highest quality of sold batteries.

RAYOVAC EXTRA are the most recommended hearing aid batteries. They are considered among the strongest on the market. They enjoy a very good reputation among users and are praised in discussion groups.

Rayovac zinc-air batteries offer very high capacity while maintaining low battery weight. They withstand high current discharge well. Additionally, they provide very stable output voltage throughout the battery's life cycle - important for many medical devices.

Batteries have the highest energy density among all miniature batteries (3x greater than silver batteries and 5x greater than alkaline batteries). Additionally, batteries operate correctly in a very wide temperature range: from -10 to 50°C.

• Hearing aid batteries are among the most capacious on the market.

Ideal choice for people seeking the highest quality batteries for their hearing aid.

Each battery is packed in a special protective packaging ensuring tightness - all so that the customer receives a product as fresh as possible, with full functional properties.

Hearing aid batteries have universal markings with numbers and colors

Size 10 / PR70 - always have yellow markings on blisters and bulk packaging (dimensions: 5.8 x 3.6 mm)

Size 675 / PR44 - always have blue markings on blisters and bulk packaging (dimensions: 11.6 x 5.4 mm)

Excellent compatibility and current performance - Rayovac Extra batteries will work in any hearing aid, they also work with modern hearing implants and speech processors!

High density of stored charge - 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 original packaging remain fully usable for several years! Rayovac Extra batteries can be bought in advance, their nominal durability 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 structure - only then the battery activates and reaches the appropriate voltage for operation. During battery use, also ensure that the battery compartment has the possibility of 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 and cold ones, e.g. in the fridge - this reduces their lifespan). Additionally, remember to turn off the hearing aid at night and when it will not be used for a long time. It is also recommended to leave the battery compartment in the hearing aid open at night - this prevents moisture from settling in it, which negatively affects batteries.

• Avoid: using batteries other than zinc-air (alkaline batteries are much weaker and may leak). Avoid keeping discharged batteries in the hearing aid or mixing batteries of different brands or new batteries with old ones - always replace the entire set. Do not keep batteries loose together with metal objects.
• What shortens battery life: higher amplification level in the hearing aid, enabling additional functions, being in noise, long phone conversations (at the ear), high air humidity, high or low temperatures, air pollution.
