📞 Synergy Digital Cordless Phone Battery (Ni-MH, 2.4V, 800mAh) - Compatible with Radio Shack 23-930, Uniden BT-1018, BT-1011, BT-1022, BT8001, BATT-6010, BT18 Battery Review

I bought these for a relative to upgrade her phones. They are working well at the moment so I would recommend these batteries for their original functionality. I have no reason to use them for a long time.

Bought to replace the original. Arrived and installed quickly. Charging takes several hours. Works perfectly. Only comment: the wires are longer than they should be, making it difficult to put the cap on properly. We succeeded.

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.
