THESE BATTERIES ARE DEFECTIVE. Obviously it's seconds. After I replaced the batteries in my cordless phones with one of them, the message "not registered" appeared on the phone screen and I was asked to place the phone on the main base for four seconds. Some phones registered after 40 seconds or more and then kept getting "NOT REGISTERED". I'm going to a REAL radio shack with one of these batteries and a phone to see what they can do. I am not satisfied in any way, shape or form.
