Yes, they can. As a matter of fact in most areas, if you have a cell phone but don't have service on it you can still use it to dial 911. Of course you still have to have it charged. A lot of people who don't want to have the bill but want the security of being able to call for assistance while driving get a used cell phone and keep it in their car. Old cell phones (working ones) can also be donated to womens shelters for the women who may need to call for emergency.

I also charge my cell in my car when needed but my car doesn't have to be running to charge. You should check because alot of cars are made like that now.
