Lithium batteries are among the most commonly used energy storage units used in today’s electronic devices. While they present distinct performance advantages in comparison with other forms of battery technology, lithium batteries also present distinct safety concerns that must be addressed to ensure safety for end-product users and avoid catastrophic battery failures.

Lithium battery testing includes simulating the abuse a battery can take across a number of conditions including installation, transportation, aging over time and also it’s hardiness to operate as expected while maintaining physical integrity in environmental conditions such as earthquakes, averse temperatures, flooding, and fire.

As part of our nationwide locations, MET Labs’ Silicon Valley laboratories can provide a wide range of compliance solutions for UN/DOT 38.3 compliance. MET’s battery test lab can evaluate your lithium batteries for compliance to safety, environmental hardiness, and transportation regulations. We help you ensure cell and battery compliance to attain the certifications needed for your demanding time-to-market needs in order to gain access to North America, Europe and international markets. Our streamlined testing process ensures your batteries are in accordance with government, regulatory, or industry standards based on your compliance needs.
