Doze:
Greater temp range is just an engineering problem, but to have such
failures so early in the life cycle suggests a design issue / inadequate
development and testing. I would be surprised if this comes down
to a "bad batch of batteries".
I think gums said something about li being used in some mil a/c. It's
also used in some Airbus models, fwih. Wonder what their experience is
and if they have had any problems ?.
