According to complaints filed on Friday, Energizer agreed "under pressure from Walmart" to inflate wholesale battery prices for other retailers starting around January 2018, and require those retailers not to undercut Walmart on price.
Walmart rivals allegedly risked higher wholesale prices or being cut off by Energizer, the largest U.S. disposable battery maker, if they charged less at checkout than Walmart, the world's largest retailer.
According to the plaintiffs, Energizer's share of the U.S. disposable battery market has risen to more than 50% from 40% in 2018.
The cases in the U.S. District Court, Northern District of California, are: Copeland et al v Energizer Holdings Inc et al, No.
23-02091, and Schuman et al v Energizer Holdings Inc et al, No.
