Active Core Plus™ with Air Optimisation features:
New Air Optimisation System
As zinc batteries use oxygen to activate, this new durable design uses air more efficiently to deliver consistent performance in all weather conditions.
We’ve optimised the ingredients we put inside the cell, so hearing aid users get more life out of every battery.

Our new harder-working battery delivers even longer-lasting power – Up to 8 hours more battery life*** – offering the reliability that people need with the latest hearing devices.
Every RAYOVAC® battery is packed with over 100 years of innovation. Active Core Plus™ with Air Optimisation is our best yet – expertly controlling airflow to deliver new levels of consistency and performance so you can be sure that no other battery lasts longer**.
