Sent me a battery that is NOT DETECTED by my Dell Precision Laptop and want me to return it at my cost as if it was a warranty (USED) claim. IT IS NOT USED, IT IS DOA and should just be replaced promptly. I will just file a claim with my Credit Card company since you won't stand behind your product. If you want it back you can send me a return label, otherwise it'll go in the garbage where it belongs.
