Attorney General Letitia James is warning New Yorkers of the potential dangers of e-bike batteries.

James' office says e-bike and e-scooter batteries led to 79 injuries and four deaths in New York City.

James offered tips on how to safely handle them, including buying an e-bike and battery from a trusted manufacturer and carefully checking the battery from time to time. Officials suggest charging the battery using only the cord and power adapter provided by the manufacturer as well.
