The extension of the program to Boston was announced on Monday.
The "No Charge to Charge" program is available now at Nissan Leaf dealers in the Boston market.
The promotion includes access to fast chargers that can charge a Leaf battery pack from empty to 80 percent in about 30 minutes, as well as 240-volt chargers spread throughout the Boston area.
Boston is the 17th market in the U.S. where Nissan has launched the "No Charge to Charge" program.
The U.S. Department of Energy says there are 9,929 public-charging stations for electric vehicles in the U.S. with 25,803 charging outlets. Most of them are clustered on either coast.
Edmunds says: Car shoppers in Bean Town get another good reason to consider the Nissan Leaf.
