Energy Assurance Testing Capabilities


At Energy Assurance we utilizes our extensive knowledge of batteries and testing to provide the battery powered product industry with a comprehensive, affordable and responsive testing resource to help our clients verify the performance as well as achieve the necessary compliance needs of their portable batteries.  We are an accredited battery testing lab with certifications from TÜV SÜD America, Underwriters Laboratories, ANAB and IECEE.


We strive to establish a long term relationship with our customers by offering industry specific advice to assure our cell and battery manufacturing customers are able to deliver products into their global markets on time and performing properly.  A large part of this is our focus on working with our customers as early in the development process as possible to mitigate risk.  This is done by developing an up front understanding of the standards and requirements that their product will be subjected to – including design impact and failure criteria.  The rapport we establish with our customers is what sets Energy Assurance apart.
