The FAA's summary their words, unchanged

These special conditions are issued for non-rechargeable lithium battery installations on The Boeing Company (Boeing) Model 747- 8 series airplanes. Non-rechargeable lithium batteries are a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
