Exponent

Its battery work covers failure analysis, design review, safety and recall support, risk assessment, vendor and cell evaluation, supply chain services, and custom safety, performance and certification testing. It also handles intellectual property cases and medical device battery safety.

Exponent began in 1967 as Failure Analysis Associates. Three Stanford University professors and two engineers from Stanford Research Institute founded it to find the root causes of accidents and failures. Its engineers test batteries at its Natick lab.
