6 x Power One Varta 312 hearing aid batteries

The company Varta is one of the world leaders in the production of batteries and accumulators. Hearing batteries, zinc-air Power One belong to the line of specialist batteries - dedicated to hearing aids and other medical devices requiring a reliable and efficient power source.

Batteries made in Germany are among the most valued batteries of this type on the market.
Their success is due to: high quality, reliability, very long lifespan.
Batteries are very often recommended on portals, discussion groups, often added as factory equipment of some hearing aids.

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

Hearing aid batteries have universal markings by numbers and colors:

• 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 structures - only then the battery activates and reaches the appropriate voltage for operation. During battery use, also ensure that the battery compartment allows 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, remember 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 open overnight - this prevents moisture buildup, 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 device or mixing batteries of different brands or new with old batteries - always replace the entire set. Also, do not keep batteries loose together with metal objects.
• What shortens battery life: higher amplification level in the device, enabling additional functions, being in noisy environments, long phone conversations (held to the ear), high humidity, high or low temperatures, air pollution.
