Hearing aid batteries guarantee stable and efficient power supply in difficult working conditions.
Zinc Air technology has become the absolute industry standard for medical sound amplification equipment. Unlike traditional alkaline or lithium solutions, these cells activate only when the air protection film is removed and the internal chemistry comes into contact with oxygen. The model line covers all the most demanded formats - ZA675 (580mAh), ZA312 (160mAh), ZA13 (265mAh) and ZA10 (90mAh), providing a constant 1.45V voltage. This electrochemical architecture provides the highest possible energy density in a microscopic size, guaranteeing stable sound of hearing aids without sudden frequency drops.
Physical and technical features:
- Air activation: Maximum energy density responding to oxygen.
- Stable discharge: 1.45V technology prevents sound distortion in the device.
- Size variety: Covers all the most popular audiology system standards.
Accurate and reliable power supply is the foundation for continuous and comfortable use of medical equipment by patients. In turn, medical personnel analyzing data and filling out documentation during night shifts will be greatly assisted by Rechargeable Desk Lamps. Safety standards require the use of only certified and tested elements in the equipment. Properly selected components that meet technical specifications significantly extend the operating cycle of the hardware in extreme working conditions. Careful selection of materials and engineering during the manufacturing process ensure maximum reliability and safety in all technical application scenarios. This analytical approach is fundamental to today's demanding industrial needs, where there is no room for error and where energy efficiency is always a primary requirement for any reliable system.
Q: How do Zinc-Air (1.45V) hearing aid batteries work and why is a protective sticker applied to them?
Q: How to properly activate a Zinc-Air battery before inserting it into a hearing aid?
Q: What do the color codes (yellow 10, orange 13, brown 312, blue 675) on hearing aid batteries mean?
Q: Why does the lifespan of Zinc-Air batteries shorten in very dry or very humid air environments?
Q: Why shouldn't a depleted Zinc-Air battery be left in the hearing aid after its operation ends?
A: In Zinc-Air batteries, oxygen from the surrounding air is used as an active reagent, entering the zinc anode through micro-pores. The colored protective sticker seals the air vents and prevents the electrochemical reaction from starting before use, ensuring a 5-year storage resource in an unopened state.
Q: How to properly activate a Zinc-Air battery before inserting it into a hearing aid?
A: After tearing off the colored sticker, the battery must be kept in the open air for exactly 1 to 2 minutes before insertion into the device. During this time, oxygen completely fills the cell's internal volume, ensuring that the VIDEX Zinc-Air battery reaches a stable 1.45V working voltage and full current output.
Q: What do the color codes (yellow 10, orange 13, brown 312, blue 675) on hearing aid batteries mean?
A: The color codes are an international IEC standard marking that helps unmistakably select the battery size and capacity. Yellow 10 (5.8 x 3.6 mm, ~100 mAh), brown 312 (7.9 x 3.6 mm, ~180 mAh), orange 13 (7.9 x 5.4 mm, ~310 mAh), and blue 675 (11.6 x 5.4 mm, ~640 mAh) match a specific size device socket.
Q: Why does the lifespan of Zinc-Air batteries shorten in very dry or very humid air environments?
A: Zinc-air electrochemistry is directly dependent on the ambient humidity level. In high humidity (above 80%), water vapor is absorbed into the battery, diluting the electrolyte, while in dry air (below 20%) the electrolyte evaporates, so the optimal working environment is 40–60% relative humidity.
Q: Why shouldn't a depleted Zinc-Air battery be left in the hearing aid after its operation ends?
A: After complete discharge, the open air micro-vents allow the internal zinc compound to react with the air, forming white zinc oxide discharge. Leaving an empty battery in the device can cause this discharge to clog the hearing aid's micro-contacts and cause corrosion.
