According to the RCMP, the number of occurrences involving harmful counterfeit products has increased from 11.5 per cent of all counterfeits investigated in 2005 to 30.4 per cent in 2012. This includes toys, pharmaceuticals, perfumes, integrated circuits, headphones, batteries and more.

While no cases of fire or injury have been reported, the world leader in standards development, certification services and product evaluation, is warning consumers and retailers that the blocks branded batteries have never been tested or evaluated by CSA Group against standards in Canada or the United States.


CSA Group recommends that owners of the products discontinue use immediately and contact the retail point of sale or distribution.
