Bill, Your initial question was perfectly valid. My cynical response was only to point out that when management is questioned, they call out the legal rottweilers who advise that no further information be released (CoverYourAss). There does not appear to be any high current disconnect device within the Thales battery case and no apparent control signals to activate one. To me, breaking the circuit at a distance from the battery under high temperature/corrosive atmosphere circumstances would not be optimal engineering. Unfortunately CRM is a lucrative field for corporate lawyers to tap but they will ignore you when Boeing has deeper pockets. It's unlikely that anyone will give you a straight answer to your question when $$$$ are involved. Cheers, KMD
