    Great replacement battery for my Uniden cordless phone model# DCT6485. It is a direct replacement for battery model# BT-446 and as I have learned, those replacements are not always created equal. The one I bought prior to this from Smartbatts (Sm44600) was absolute garbage and lasted less than a year. The cord to connect it inside the battery compartment was too long and got snagged in cover when closing, making for an awkward fit. This one form was a perfect fit and delivered everything I expected (more than fair price, extremely reasonable shipping). A great product at an awesome price! Very happy.

    Bought these about six months ago and they are still going strong. I don't expect to have to replace them anytime soon. Great item. You always get great value with Overstock especially taking advantage of their awesome deals. Have bought from Overstock many times and they always treat me right.
