Varta is one of the world's leading battery and accumulator manufacturers. Power One zinc-air hearing aid batteries belong to the line of specialist batteries - dedicated to hearing aids and other medical devices requiring a reliable and efficient power source.

• They owe their success to: high quality, reliability, very long service life.

Batteries are often recommended on portals, discussion groups, often added as factory equipment for some hearing aids.

Their performance and long life are influenced by high capacity, and thanks to a special long tab, removing the battery from the packaging and placing it in the hearing aid is now very easy and simple.

• Batteries come from the freshest production.

Hearing aid batteries have universal markings with numbers and colours

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

Size 13 / PR48 - always have orange markings on blisters and bulk packaging (dimensions: 7.9 x 5.4 mm)

Size 312 / PR41 - always have brown markings on blisters and bulk packaging (dimensions: 7.9 x 3.6 mm)

Size 675 / PR44 - always have blue markings on 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 structure - only then the battery activates and reaches the appropriate voltage for operation. During battery operation, 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 a fridge - this reduces their lifespan). Additionally, remember to turn off the hearing aid at night and when it is not used for a long time. It is also recommended to leave the battery compartment open at night - this prevents moisture from settling in it, which negatively affects the 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 whole set. Also, 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.
