Regarding full recharges (and I'm like Harry in that I let the bar go down to 1 and then charge through the wall), I think I've done probably 10 or 11 since I bought my Reader in late December of last year.
When you think about it, if one can get approx. 200 charges on these batteries before they start to no longer hold a charge, then that would give me about 10 years before I have to send it in for a new factory battery.
