Active Core Plus™ Technology

With their all-new air optimisation technology, no hearing aid batteries last longer than the Rayovac ProLine Advanced: This creates a 10% IEC average performance improvement,  and allows the reliability and performance of Active Core Plus™ to truly stand out.

New Air Optimisation System: Because zinc batteries use oxygen to activate, this new durable design allows air to be used more efficiently in order to deliver consistent performance in all weather conditions.

Balanced Formula: With optimised ingredients inside the cell, hearing aid users can get more life out of every single battery.

Engineered for Excellence: This new harder-working battery delivers even longer-lasting power – 12% better than the nearest competitor – to ensure maximum reliability in modern hearing aid devices.

    My first order with you, it was dealt with quickly. My only complaint was packaging, I felt it was rather over the top, could have been sent in a padded envelope. Regards.

    Hi, thank you for your review. I am sorry but we are not the provider of this free service. As we are an online retailer and the NHS are not able to support us with this service as this is done privately. I would advise to contact your audiologist in which fitted you with the aids to see if this is a service they can provide you. Regards Joy, Hearing Aid Accessories
