Active Core Plus™ with new Air Optimisation technology

No hearing aid battery lasts longer**

As hearing aid technology advances, the batteries that power them have to be as sophisticated as the device itself.
That’s why we continue to invest in new technology and improve our batteries – to stay one step ahead in an ever-changing world, and power the moments we all live for.

Lasts even longer, performs even better*

Lasts even longer, performs even better*

Active Core Plus™ is state-of-the-art of technology, designed to deliver top performance for modern-day devices. And Air Optimisation is our latest innovation, creating a 10% IEC average performance improvement*. This improves both the reliability and performance of Active Core Plus™, ensuring that no other battery lasts longer**.
