After pricing this same battery pack for $17 at a local store that sells just batteries, I did an online search and saw that Amazon.com had some listings. I placed my order and received my shipment within a matter of days. I've had no problems with the battery and can once again enjoy using my cordless phone without the annoying "low battery" beep or having my calls cut off.
