Don't worry about the lack of a picture - this is the battery you need to replace your Uniden BT-446. It is an exact size replacement with the proper connector. It comes in retail (card/blister) packaging.

I have a Uniden BT-446 phone. After a couple of years, the battery started to wane and for the past several months, they would not hold a charge for longer than an hour or so. I looked around for compatible batteries and found these. They are terrific and fit/work just as they are advertised to. I can now talk for hours without recharging and leave my phones off the base charger stand for days. Its been about a month now and I think these batteries work better than the original factory ones did when I first bought the phone. Should definitely have gotten these earlier! I highly recommend these.

Bought two of these batteries to replace the factory batteries in two 5GHz Uniden cordless phones. Even though the mAH rating is the same as the factory battery, and they say that NiMH batteries don't wear out (baloney!), the new batteries more than doubled our talk time. In fact, we haven't even found the limits of our talk time using the new batteries.
