Review title: This battery did not fit in my CU400 phone
Product review: Although physically the same size as the original battery, it is notched differently. The original battery has a single notch and this battery has two notches which don't line up with the phone tab. Since the electrical connections looked the same, I modified the phone tab to make it fit but it would not charge. There must be some internal difference as well.I bought two batteries and tried them both and they both acted the same. My first attempt to make it fit was to widen the notch on one of the batteries so I guess that would make it pretty hard to return???
