Review on 6-Pack iMah BT166342/BT266342 2.4V 750mAh Ni-MH Batteries - Compatible with VTech CS6114 CS6429 CS6719-2 AT&T EL5210 EL51203 Telephones by Laura Church

Batteries don't work at all. I called AT&T to find out what battery I need for my EL52200 phone model. I have received the necessary information. I didn't want to order from them so much more expensive than your site. I made sure I ordered and matched the phone model confirmation number etc from Revain. This is the second time I've ordered batteries that don't work. Now I'm thinking maybe the phones are just too old. And the batteries are not to blame. In case anyone has the same phone model. And can give information to help, it will be much appreciated. Otherwise you will have to return the batteries after a few days. I've read other reviews from people who ordered more than one or two batteries. Maybe two out of three or four don't work. Or it could say the battery is low or something. But I've never seen any of them work. I will be returning the ones I purchased for a refund as soon as possible. Could you send me a return label, thank you.
