UCAR was a brand of Union Carbide and Carbon Corporation.

See also Eveready, the main battery brand of UCC at the time.

The brand was predominantly used in Europe. Today (2013) it is most likely owned by Energizer, as the battery division was split off UCC in the 1980s.

UCAR was originally registered as a trade mark for graphite electrodes and contacting pins thereof in 1969 [USPTO serial 72309315] in the USA.
In 1974, UCAR was registered as a trade mark in Germany [DPMA, German Patent and Trademark Office, DE923001].
A modernized logo was registered in 1976 [USPTO serial 73075486].
