6 x Duracell ActivAir 312 Hearing Aid Batteries

DURACELL zinc-air hearing aid batteries have been optimized for maximum performance during continuous constant discharge with constant current - making them superior to other similar solutions. In addition, it has been possible to provide a very stable output voltage throughout the life cycle of the battery - not without significance in the case of many medical devices.

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

Thanks to the increased size of the anode material, Duracell batteries have the highest energy density of any mini battery (2x higher than silver batteries). In addition, the batteries work properly in a wide range of temperatures: from -10 to 50 degrees. C.

Duracell batteries are the perfect choice for those looking for the highest quality batteries for their hearing aid.

Each battery is packed in a special protective packaging with a system that facilitates attachment in hearing aids (EasyTab) - all so that the product reaches the customer as fresh as possible, with full usability.

Hearing aid batteries are universally numbered and colour-coded:

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

Why choose Duracell hearing aids?

• Excellent compatibility and current efficiency - Duracell batteries will work well in any hearing aid, as they are the few that also work with modern hearing implants!
• High Accumulated Charge Density - the most capacious of all button batteries on the market, up to 5x more energy compared to alkaline cells, 2x more charge, at the same cell size, compared to lithium/silver cells.
• Flat Discharge Characteristics - Duracell zinc-air batteries offer a constant voltage (+/- 0.15V) throughout the battery discharge cycle.
• It has made a lifespan - batteries stored in their original packaging, at room temperature, retain more than 98% of capacity even after 12 months! Duracell batteries can be purchased in stock, their nominal lifespan is approx. 4 years.
• Safe and ecological - due to the cathode design, the batteries are characterized by increased safety of use. The battery is not hermetically sealed, so it is not possible to uncontrollably increase the pressure of gases in the battery (the use of a battery of a different type, in extreme cases, may end in delamination of the cell and explosion).
• Low cost of use - Duracell batteries, thanks to their extended life, are cheap to operate - longer intervals between battery replacements result in visible savings.

How to fully appreciate the advantages of zinc-air technology?

• After removing the protective sticker, wait at least approx. 2 minutes before the battery is started 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, care must also be taken to ensure that the battery compartment is able to penetrate the air further.
• 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 places, e.g. in the refrigerator - this reduces the lifespan). In addition, it is worth remembering to turn off the camera at night and when it is to be unused for a long time. It is also recommended to leave the battery compartment in the camera open at night - this will prevent moisture from settling in it, which has a bad effect on the batteries.
• Beware: use of batteries other than zinc-air batteries (alkaline batteries are much weaker and may spill). Avoid keeping dead batteries in the camera or mixing batteries of different brands or new batteries with old ones - always replace the entire set. Also, do not keep the battery loose together with metal objects.
• What shortens battery life: higher level of gain in the camera, inclusion of additional functions, being in noise, prolonged talking on the phone (by the ear), high humidity, high or low temperatures, air pollution.
