As I understand, Chevron's patent control over large-format NiMH batteries means that no other company but them can produce such batteries.
However, why does Saft sell high-capacity (100 Ah+) NiMH batteries? http://www.saftbatteries.com/130-Catalogue/PDF/NHE_en.pdf The pdf is dated July 2005. I've heard about new NiMH batteries that avoid patent troubles, such as "bi-polar" NiMH batteries. http://www.electroenergyinc.com/products/technicalpapers/BipolarNickel.pdf How long have these been around? _______________________________________________ Florida EAA mailing list [email protected] http://www.floridaeaa.org
