Implantable Medical Equipment Batteries

Resonetics® designs and manufactures the broadest range of electro-chemistries for implantable applications, including medical lithium ion batteries. In 2022, we acquired EaglePicher Medical Power’s medical device batteries to expand our product portfolio with technology uniquely designed for miniaturized implantable and wearable devices.

Medical Batteries for Every Need

Li-Ion Chemistry

Offering the highest energy density and discharge rate among rechargeable implantable batteries. Available in multiple configurations from under three mAh to 440 mAh for neuromodulation, cochlear implants, drug delivery, and ventricular assist devices.

Li/CFs-MnO2 Chemistry

With medium energy density, high-rate discharge, and excellent shelf life, these batteries provide reliable performance. These are commonly used for pacemakers, implantable cardioverter-defibrillators, and monitoring devices.

Li/CFx Chemistry

With the highest energy density and low- to medium-rate discharge, these batteries offer excellent shelf life. Available in multiple configurations ranging from under 200 mAh to over 9.5 mAh, these are commonly used for pacemakers, neuromodulation, drug delivery, and monitoring devices.

Wireless Charging

Resonetics has partnered with Resonant Link to deliver industry-leading wireless charging solutions. Their 2.5W Titanium-Compatible Wireless Charging Platform for Implantable Medical Devices features the Resonetics Contego 440 mAh lithium-ion battery.
