84 month battery warranty means nothing unless you...

84 month battery warranty means nothing unless you install new battery in their shop. I bought a battery in Feb '16. It died yesterday. To get the prorated warranty claim, I was told I got to have the battery installed in their shop. Hmm, I can not get the engine started, how am I ever to drive the car to their place? Get the car towed to their place? or jump start the car and pray it doesn't get stalled on the way? Never heard a warranty claim is contingent on another new buy. 84 month warranty is just a ploy to get you hooked, and later using create ways to deny warranty claim.
