Stalemate?

Bear,

Remembering the "wise" words on 999% or similar. (Boeing could need US Treasury funding). Better to "fire" Li Ion and revert to Ni Cds...

I am curious to learn on the conditions of the other 94 batteries in the other (47) planes. This may solve more easily the puzzle. Just CT can show a lot. And the surviving ones could be used again. For APU.

Technical point:

Why not have a mix of Li Ion and Ni Cds:

If a EFFECTIVELY PROTECTED Li Ion fails a smaller Ni Cd enters in the circuit. This can be easily made in the A/C main battery section.

For APU it could be adequate the Li Ion (after the review)
