6 x Duracell ActivAir 10 hearing aid batteries

DURACELL zinc-air batteries for hearing aids have been optimized to achieve maximum performance during continuous discharge at a constant current - thus surpassing other similar solutions. Additionally, it has been possible to ensure very stable output voltage throughout the entire battery life cycle - which is significant for many medical devices.

Duracell zinc-air batteries are innovative cells - the main component of the chemical reaction at the cathode is air!

Thanks to the increased size of the anode material, Duracell batteries have the highest energy density among all mini batteries (2x larger than silver batteries). Additionally, the batteries operate correctly in a very wide temperature range: from -10 to 50°C.

Duracell batteries are the ideal choice for those looking for the highest quality batteries for their hearing aids.

Each battery is packaged in a special protective packaging with a system that facilitates placement in hearing aids (EasyTab) - all to ensure that the product reaches the customer as fresh as possible, with full usability values.

Batteries for hearing aids have universal designations by numbers and colors:

• Size 10 / PR70 - always have yellow markings on the blisters and bulk packaging (dimensions: 5.8 x 3.6 mm)
• Size 13 / PR48 - always have orange markings on the blisters and bulk packaging (dimensions: 7.9 x 5.4 mm)
• Size 312 / PR41 - always have brown markings on the blisters and bulk packaging (dimensions: 7.9 x 3.6 mm)
• Size 675 / PR44 - always have blue markings on the blisters and bulk packaging (dimensions: 11.6 x 5.4 mm)

Why choose Duracell hearing aid batteries?

• Exceptional compatibility and current efficiency - Duracell batteries will work in any hearing aid, as few also work with modern hearing implants!
• High energy density - the most powerful among all button batteries available on the market, with 5x more energy compared to alkaline cells, 2x more charge at the same cell size, compared to lithium/silver cells.
• Flat discharge characteristic - Duracell zinc-air batteries offer a constant voltage (+/- 0.15V) throughout the entire battery discharge cycle.
• Excellent shelf life - batteries stored in their original packaging, at room temperature, retain more than 98% of their capacity even after 12 months! Duracell batteries can be bought in bulk, their nominal lifespan is about 4 years.
• Safe and eco-friendly - due to the construction of the cathode, the batteries are characterized by increased safety of use. The battery is not hermetically sealed, which prevents uncontrolled gas pressure build-up in the battery (using batteries of another type, in extreme cases, can result in cell rupture and explosion).
• Low operating cost - Duracell batteries, thanks to their extended lifespan, are inexpensive to operate - longer intervals between battery replacements lead to noticeable savings.

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 allows 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 advisable 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, activating additional functions, being in noise, prolonged phone conversations (at the ear), high or low humidity, high or low temperatures, air pollution.
