What is Active Core Technology? How has it helped achieve longer life in your batteries?


Active Core Technology is our newest and most advanced generation of hearing aid battery technology. It is comprised of a series of innovations we made to achieve longer battery life. We optimized the can of the battery to be able to fit more critical ingredients in the battery to give users that longer life. We improved the anode to ensure quality performance and steady voltage throughout the life of the battery. This helps eliminate low voltage beeps that users sometimes received before the battery was actually dead. Lastly, we have improved the battery seal to provide cell stability in extreme environmental conditions. This new technology is the perfect complement to our new packaging. Our number one priority when innovating was to prolong battery life because from our research we learned that hearing aid users ranked battery life as the MOST important factor when choosing hearing aid batteries. This led us to develop Active Core Technology, which gives users up to two days longer battery life than our previous formulation. With ACT we have developed our longest-lasting hearing aid battery yet.
