Senator Charles Schumer says knockoff cell phone batteries are becoming a dangerous problem.
Schumer says there have been more than 60 reports nationwide of cellphone batteries causing phones to expand, catch fire and sometimes explode, injuring the user.
He says the knockoff and counterfeit batteries causing the problems are usually made in China.
He's asking the Consumer Product Safety Commission to investigate and warn consumers which cellphone batteries are risky, and to consider banning them.
"The number of batteries that are imported is increasing, and the standard battery makers are being pushed aside by cheap batteries that are much more dangerous than the batteries that we're used to," Schumer said.
Schumer says many of the foreign manufactures use established brand names to gain consumer trust.
