Duracell Size 675 Activair Hearing Aid Batteries 60

Duracell Size 675 Activair Hearing Aid Batteries

This pack supplies sixty genuine Duracell Size 675 zinc-air hearing aid batteries. Each cell delivers a nominal 1.45 volts and is designed for high-capacity performance in compatible hearing instruments. The batteries arrive inside a protective plastic case that keeps them secure and organised. Long tabs on every cell make handling and insertion straightforward for daily use.

Replaces depleted Size 675 cells

These batteries replace exhausted Size 675 zinc-air cells in any hearing aid specified for that size. The jump is worth it when your current cells no longer hold a charge long enough for a full day of wear. Fresh zinc-air chemistry restores the intended runtime and consistent voltage output. The sixty-count pack reduces the frequency of reordering for regular users.

Zinc-air chemistry requires air activation

Zinc-air cells only begin producing power once the protective tab is removed and air enters the cathode. Removing the tab too early starts the discharge process and shortens usable life. The batteries must be stored sealed in their case at room temperature until needed. They are not rechargeable and cannot be used in devices requiring other battery chemistries or sizes.
