Review on GEILIENERGY BT-1015 BT1015 Battery: Uniden BT1007 Compatible, BBTY Series Replacement for Cordless Phone - 4-Pack by Sandra Allen

Batteries fit perfectly into the Uniden DECT 1580-4 cordless telephone socket. However, I had some trouble opening the battery compartment cover again due to the very tight fit between the battery and the connection cable. For the first year, the batteries held their charge well and I was able to make hands-free calls for more than an hour. Then the charge of several batteries was reduced to thirty minutes, and one battery lasted only ten minutes. I was just trying to swap out a BT-1007 battery and the connector didn't fit my phone properly. So I'll be ordering these batteries again and I'm hoping to get better long-term results this time.
