New requirements for Secondary Battery Packs under UL 60950-1, 1st Edition
There were numerous recalls of batteries and battery packs used with ITE (Information Technology Equipment) in the late 1990s and early 2000s, and they continue today. Several years ago the largest ITE Industry group in the United States, the Information Technology Industry Council (ITI), proposed to revise UL 60950 and require that Secondary (Rechargeable) Battery Packs used
with Transportable Equipment additionally comply with UL 2054, Household and Commercial Batteries as a component requirement.
