I wonder if there wasn't a not so good batch of Mega's that slipped through recently. I've been using mine for 5 months without any problems (I have a couple of them), and all of a sudden I see people with issues. I've not had any problems at all with the batteries in the pcc. However, they've always said 3 to 4 full charges of the batteries, and I've always gotten at least 3, and once in a while 4, before having to recharge the pcc.
