As a CPF member and fairly frequent flyer I knew that Li-ON fires could be extinguished by an ordinary ABC extinguisher, but lithium primary (lithium metal) fires could only be extinguished by a class D (metal powder especially nickel) extinguisher. Since commercial aircraft only carry "ordinary" cabin fire extinguishers I found this disturbing because it meant that a lithium primary passenger cabin fire could not be put out.

Then I came across these two different Faa statements
Halon for "Small number" of Lithium Primaries

Halon NOT for "Bulk" Lithium Primaries

As home users of Lithium primaries as well as Li-ONs should we now use regular ABC extinguishers (plus water) on any lithium fire regardless of battery type?
