6 x Power One Evolution Varta 675 Hearing Aid Batteries

Varta is one of the world's leading manufacturers of batteries and accumulators. Power One EVOLUTION batteries are based on TFT (Thin Foil Technology). They have a very high energy density and a higher capacity than other hearing aid batteries.

Batteries made in Germany are some of the most valued batteries of this type on the market.
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 of some hearing aids.

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

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)

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.
