Energizer Holdings has won a preliminary injunction against Spectrum Brands, whose Rayovac battery division is based in Madison. Energizer claims Spectrum Brands has infringed on two of its patents by importing lithium batteries made in China and selling them as Rayovac Lithium in the U.S.

In a lawsuit filed in U.S. District Court in Madison in July, Energizer asked to have Rayovac stop selling the batteries and to be awarded triple damages for the Madison company's "willful infringement" of the patents.

Spectrum Brands has said it "strongly refutes" the claims.
