Questions about this item

How often will I need to replace the Size 312 zinc-air cells in my hearing aids?

Each cell delivers 1.45 V until the zinc-air chemistry is exhausted; with 40 pieces in the box you can swap fresh batteries as your devices indicate low power.

What limits continuous operation once the tab is removed?

Air enters through the Easy Tab vent and begins the reaction immediately, so the 1.45 V output declines steadily until the zinc is consumed regardless of daily load.

Do the batteries generate noticeable heat or noise during all-day wear?

Zinc-air chemistry produces no audible sound and negligible warmth while supplying 1.45 V to the hearing aid circuit.
