A warning about dangerous phone batteries:

A cheap cell phone battery could lead to an explosion in your pocket.

That's the warning from Senator Charles Schumer. The N.Y. lawmaker says counterfeit or poorly made cellphone batteries can lead to phones overheating and even exploding.

Schumer says there have been at least 60 reported instances of cell phone batteries smoking, catching fire, or exploding in the last two years.

He's calling on the Comsumer Product Safety Commission to determine the full scope of the problem.
