Implantable Medical Batteries from Resonetics Now on Chamfr

Accelerate Medical Device R&D with Proven Power Solutions

Speed and reliability are essential when developing implantable medical technologies. That’s why Chamfr now offers implantable-grade batteries from Resonetics, an industry leader in medical device manufacturing, are purpose-built for use in Class II and III implantable medical devices across the development lifecycle.

With electro-chemistries ranging from lithium ion (Li-Ion), ideal for high energy density and rechargeable use cases, to lithium carbon monofluoride (Li/CFx), known for long shelf life and high-rate discharge, these batteries help engineers streamline prototyping, reduce sourcing delays, and bring innovative devices to market faster.

Every cell is designed with precision to meet the rigorous demands of today’s most complex and life-changing medical technologies. These offerings have capacities ranging from 1.5 mAh to 440 mAh  for rechargeable cells, and 65 mAh – 1.4 Ah for primary cells. The cells are offered in both stainless steel and titanium cases in a variety of different shapes, such as prismatic, elliptical and D shaped. This full range of offerings allows Resonetics to provide you with the power source for your next project.

Powering Innovation for Med Device Engineers

Sourcing critical components like implantable batteries can be a roadblock to rapid development. By making these batteries available through Chamfr’s ecommerce platform, we’re helping medical device engineers: 

• Accelerate early-stage prototyping 
• Test and iterate faster with immediate access to power solutions 
• Avoid sourcing delays during design validation or production ramp-up 
• Reduce development friction and move closer to clinical or commercial readiness

Understanding the Battery Chemistries

Resonetics batteries are available in two specialized chemistries designed for different implantable use cases:

Lithium Ion (Li-Ion)

• Rechargeable
• High energy density
• Ideal for devices with repeated or sustained power needs
