    This Uniden BT-446 cordless phone Ni-MH battery has an integrated microchip that prevents overcharging and lengthens battery life.

    • cheaper than new phones

      Good alternative to spending 4X the price on new phones when all you need are batteries that will hold the charge.

    • They work

      I bought these about six months ago, and they have worked just fine since day 1. Great price compared to comparable batteries at the big box stores.

    • Order Extra

      The product is good and works well, but you need to order an extra one. I needed two of these batteries, but after reading the reviews, I decided to order three in case there was an issue. There was. One of the leads on one of the batteries was cut. I used the other two and was going to repair the third and keep it for a spare. I never got around to it, and just threw it away yesterday.

    • Poor plug design

      The batteries work fine but the pin contact tends to pop out when the plug is inserted. It's possible to fix it but it's a real pain. Clearly the plug design is not good enough to hold the pin in place. But then the price is very good and if you're careful they can be got to fit.

    • Works great!

      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.
