I purchased 4 of these batteries in April, 2009 from ebatteries. I used the batteries to replace the original 2420 batteries in my AT&T; E5634B cordless phone. The initial performance of the batteries was good, but unfortunately this only lasted a few months. After 6 months of use I was only getting about 15-20 minutes of talk time on two of the batteries, and about 30-35 minutes of talk time on the other two.The cost for shipping and handling was more than the cost of the batteries. The total cost of the order, including shipping and handling, was $29.40, which works out to be $7.35 per battery.
