You do have to watch aftermarket batteries.
I was looking are replacing the batteries one of my UPS units. Aftermarket batteries were a good bit cheaper, then I noticed they were 5 AH versus 7 AM. So 28% less capacity.
Phone batteries undergo many more charge cycles that readers. I chare me reader maybe once a week. I charge my phone almost every day. So I would expect the reader battery to last about 5 times as long as tehphone battery.
