Obligations
What this law requires
Each non-rechargeable lithium battery and battery system installation must be designed to maintain safe cell temperatures and pressures, under all foreseeable operating conditions, to prevent fire and explosion.
Each non-rechargeable lithium battery and battery system installation must be designed to prevent the occurrence of self-sustaining, uncontrollable increases in temperature or pressure.
Each non-rechargeable lithium battery and battery system installation must not emit explosive or toxic gases, either in normal operation or as a result of its failure, that may accumulate in hazardous quantities within the airplane.
Each non-rechargeable lithium battery and battery system installation must meet the requirements of 14 CFR § 25.863.
Each non-rechargeable lithium battery and battery system installation must not damage surrounding structure or adjacent systems, equipment, or electrical wiring from corrosive fluids or gases that may escape in such a way as to cause a major or more severe failure condition.
