6 x batteries for hearing aids Power One Evolution Varta 675

The company Varta is one of the world leaders in the production of batteries and accumulators. The Power One EVOLUTION batteries are based on TFT (Thin Foil Technology). They are characterized by very high energy density and greater capacity than other batteries for hearing aids.

Batteries made in Germany are among the most valued batteries of this type on the market.
They owe their success to: high quality, reliability, very long lifespan.
Batteries are often recommended on forums, discussion groups, and are often included as standard equipment in some hearing aids.

Their performance and long lifespan are influenced by high capacity, and thanks to a special long handle, removing the batteries from the packaging and placing them in the hearing aid is now very easy and simple.
The batteries come from the latest production.

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)

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 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. It is also prohibited to keep batteries loose together 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.
