HearClear Battery Size 675 PR44 Blue Tab 120 Cells

HearClear Size 675 Zinc Air Batteries

This pack delivers 120 zinc air cells sized 675 with blue tabs for hearing aids. The batteries are made in the USA with US and global parts and come in 20 standard dial packs of six cells each. They offer a long shelf life of approximately three to four years. The formulation balances high capacity, high power and an anti-leakage design.

1.45 Volt Standard and Tab Activation

These cells operate at 1.45 V and use zinc air chemistry that activates when the blue tab is removed. Air must reach the cathode for the reaction to start, so the tab stays in place until the moment of use. Once activated, the cell cannot be sealed again and will discharge continuously. Voltage and capacity are defined by the size 675 standard.

Check Device Compatibility Before Use

Confirm that your hearing aid or cochlear implant specifies size 675 or PR44 cells before ordering. The product line also includes sizes 10, 13, 312 and a 675P cochlear variant, which are not interchangeable. Ensure you can store the unopened packs at room temperature to preserve the stated shelf life.
