This document contains Minimum Operational Performance 
Standards (MOPS) for rechargeable Lithium battery systems to be 
used as permanently installed power sources on aircraft.  
Compliance with these standards is recommended as a means of 
assuring that the Lithium battery will perform its intended 
function(s) safely, under conditions normally encountered in 
aeronautical operations.  These standards apply to the chemical 
composition, cell size, cell construction, cell interconnection 
methods within batteries, venting provisions, operational and 
storage environments, packaging, handling, test, storage and 
disposal of rechargeable Lithium batteries, installed 
separately or in avionics equipment aboard aircraft.
