Yes you can. You can take your old battery to exchange it for another battery. If don't take your battery he will charge you extra for the core of the battery. It's like $10 extra without the exchange.
Yes you can...! It works as a Core, you bring your old one in and get a new one out with 1 Year Warranty...! You can also ask him for a stronger one if he has it he'll give it to you for the same price...!
