PowerOne Size 312 Hearing Aid Batteries

These zinc-air cells deliver a steady 1.45 Volt output for hearing aids that use size 312 batteries. The pack contains 60 mercury-free units in a single box, suited for daily wearers who prefer a long-lasting supply.

Sustained discharge performance

Zinc-air chemistry maintains a flat voltage curve throughout most of the discharge cycle, so sound quality stays consistent until the cell is nearly depleted. Once the protective tab is removed, the battery activates on contact with air and cannot be resealed.
