Energy Assurance is an accredited battery test lab with Underwriters Laboratories as a member of the Data Acceptance Program with Underwriters Laboratories Inc.  The Data Acceptance Program (DAP) provides a means for UL to accept Energy Assurance test data as an external test lab in support of obtaining the UL Mark certification.  Furthermore, Energy Assurance can perform testing under the standards with our scope without UL witnessing of the testing, because we have undergone an extensive technical and quality systems audit by UL. 


Additionally, Energy Assurance LLC is an accredited battery testing lab for several IEC portable battery standards including IEC 62133.  We have been accepted as a member of the IECEE CB Scheme as a Certified Bodies Test Lab (CBTL).  Energy Assurance is entitled to operate as a CBTL under the responsibility of UL (Demko) as our National Certification Body (NCB).
