Μπαταρία μίας χρήσης GP Batterien 103251 675 PR44 ψευδαργύρου-αέρα

The GP Batteries 103251 675 PR44 Zinc-Air is a single-use battery engineered for hearing aids and other compact electronic devices that require a reliable power source. With zinc-air chemistry and a standard 675 / PR44 size, this battery delivers stable voltage and a consistent discharge profile suited to devices with continuous low-current demands. The design features an activated air inlet seal that is removed before first use to begin stable power output.

Advantages

These zinc-air cells offer a high energy density for their size, providing extended runtime compared with some other primary battery chemistries in similar form factors. The 675 size is widely accepted across hearing aid models, ensuring broad compatibility. The single-use construction means no charging is required and the battery maintains capacity during storage with a protective seal until activation. The consistent voltage under typical hearing-aid loads helps maintain device performance and predictable battery life.

Suitable for

• Behind-the-ear and in-the-ear hearing aids that use 675 / PR44 cells
• Small medical and assistive devices requiring zinc-air batteries
• Portable low-current electronics where long shelf life and steady discharge are needed

Key specifications

• Chemistry: Zinc-air (air-activated)
• Size designation: 675 / PR44
• Cell type: Single-use (primary) battery
• Typical operating voltage: nominal voltage suitable for hearing-aid applications
• Form factor: button cell with pull-tab activation
• Storage behavior: sealed until activation to preserve capacity

How to use

Before installation, remove the protective sticker or pull-tab covering the air inlet to activate the zinc-air cell; wait the manufacturer-recommended short period for the cell to reach nominal voltage if indicated in the device manual. Insert the battery into the hearing aid or device following the polarity markings and the device manufacturer’s instructions. Ensure the battery compartment is clean and dry, and close it securely. Replace the battery when audio performance decreases or when the device indicates low battery according to its normal indicators.

Recommendations

Store unused batteries in a cool, dry place away from direct heat and sunlight. Use batteries before the stated expiry date and avoid attempting to recharge single-use zinc-air cells. Dispose of used batteries according to local regulations for battery recycling or hazardous waste.
