HEAR Premium Grade Zinc Air Batteries in brown, size 312 come in a set of 60 batteries and provide you with the performance, power, reliability and consistency to live life to the full.

These fresh, mercury-free batteries are a fit for all modern hearing devices, optimised for wireless, bluetooth and MFIs devices with a secure and precise sealant application to provide cell stability and durability in extreme conditions.

The technology is a major step forward in the world of hearing aid battery power.  An advanced anode increases battery life and ensures long lasting performance throughout the life of the battery.  The zinc air battery creates power by oxidising zinc with oxygen from the air.  The design delivers energy where it’s needed, prolonging the life of the battery and ensuring a consistent and precise listening experience.  The tabs are 25% larger than standard tab design, and ergonomically designed to make changing your hearing aid battery easier.
