bubbers...really?
Lets just suspect that you have at least a basic 4th grade education, and I will go out on a limb on that, it is very easy to determine that the batteries were made by a Japanese Company, in fact, much of the aircraft was made in Japan...
You will also find that there are virtually NO batteries made in the US.
It appears you have internet, so do a search for where the parts of Boeing aircraft are made. You will find that virtually the entire aircraft parts are made outside the US, and ASSEMBLED in the US.
