    • Ni-MH Cordless Phone Battery for Uniden BT-446

      So many times when you cordless phone stop holding a charge you loo for the batteries but you either can not find them or they are prices too high and it would be cheaper buying a new cordless set up. But I was lucky that you were selling the right batteries for my phone system. The price was below $20.00 for the four that I needed and i am so happy that you had the Ni-MH which will not let them overcharge.I would recommend that before you go buy a new phone system checkout the site for a better deal on batteries.

    • Uniden Cordless Phone Battery

      Great price! I had previously purchased these batteries directly from Uniden - BIG MISTAKE! Their prices were ridiculous AND they charged for shipping! This was an excellent deal!

    • Great buy

      I ordered this for my phones attempting to save them from death. They were shipped and received within a few days. This was certainly cheaper than buying new phones!
