30 x Duracell ActivAir 13 hearing aid batteries

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

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

Due to the increased size of the anode material, Duracell batteries have the highest energy density of all mini batteries (2x higher than silver batteries). In addition, the batteries work properly in a very 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 aids.

Each battery is packed in a special protective packaging with a system that facilitates placement in the hearing aids (EasyTab) - all this to ensure that the customer receives a product that is as fresh as possible and fully functional.

Hearing aid batteries are universally marked with numbers and colors:

• 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 blisters and multipacks (dimensions: 11.6 x 5.4 mm)

Why choose Duracell hearing batteries?

• Excellent compatibility and current efficiency - Duracell batteries will work well in any hearing aid, as few also work with modern hearing implants!
• High charge density - the most capacious of all button batteries on the market, up to 5x more energy compared to alkaline cells, 2x more charge, with 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.
• Excellent lifespan - batteries stored in the original packaging, at room temperature, retain more than 98% of their capacity even after 12 months! Duracell batteries can be purchased in stock, their nominal durability is approx. 4 years.
• Safe and ecological - due to the design of the cathode, the batteries are characterized by increased safety of use. The battery is not hermetically tight, so it is not possible for an uncontrolled increase in gas pressure in the battery (the use of a different type of battery, in extreme cases, may end in cell stratification 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 the operation of the battery, it is also necessary to 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 refrigerator - this reduces the life). In addition, it is worth remembering to turn off the camera at night and when it is to be left unused for a long time. It is also recommended to leave the battery compartment in the camera open overnight - this will prevent moisture from settling in it, which has a bad effect on the batteries.
• Beware: the use of batteries other than zinc-air (alkaline batteries are much weaker and can spill out). Avoid keeping dead batteries in the camera or mixing batteries of different brands or new and old batteries - always replace the entire set. Also, do not keep the battery loose with metal objects.
• What shortens the battery life: higher level of gain in the camera, activation of additional functions, being in noise, prolonged phone conversation (next to the ear), high air humidity, high or low temperatures, air pollution.
