Lithium Ion Batteries: Exposing Safety Risks Via Testing on a Budget

Contributed commentary by John C. Copeland, VP/COO, Energy Assurance LLC

As a commercial test lab specializing in regulatory and performance testing of rechargeable lithium batteries, we assist a wide variety of clients spanning all aspects of the electronics industry.  Many come from highly-regulated product types that typically have well established requirements for safety, quality, and reliability.  They also tend to have the engineering and compliance resources to support these requirements, and as such, command a corresponding price premium.  In short, they inherently understand the value of testing favoring a more proactive approach.  Read more about Lithium Ion Batteries: Exposing Safety Risks Via Testing on a Budget

A Review of America’s First Step Towards the Harmonization of Portable Battery Standards: UL 62133

John C. Copeland, VP/COO • Energy Assurance LLC

Although not widely publicized, Underwriter’s Laboratories (UL) released a new battery standard applicable to rechargeable lithium cells and battery packs in early January 2015.  This standard, UL 62133 (Revision 1), takes its place among other country-specific versions of the IEC 62133 international standard which has been in active use for global battery approvals for many years.  Why is this important?  After all, do we really need another battery standard?  As it turns out the answer is a definite “Yes” and is driven by a single concept – Harmonization.
