Yes they do and I believe that it's what the cost of your battery is!
Batteries Plus.
I'd go to Batteries Plus. Still, I don't have any idea what it costs to purchase a battery for an I phone. I'm pretty sure they'll remove and replace the battery no charge once you purchase one.
Depends on where you go, but the best place is battery plus. You just pay for the right battery that you device needs, and they charge is for you..
