Battery probs after being left uncharged = scam?

I bought an Edge on Ebay - described to be new and "sealed box", but it arrived unsealed.

The seller explained, among other things, that these models are "known to have battery problems if not
charged for a long time" and so she opened each box and charged them for a short time, checked the backlight, and put them back in the box.
The unit does look new, and she shipped some units sealed. I'm trying to figure out if she's not too bright, or up to something.

So has anyone ever hear of this "battery problem"?

yes and no

Li-ion batteries have a tendency to fail if left uncharged for extended periods---At least that's the general consensus of "experts"---

This is from a li-ion info web site--

Sorry --I don't have the URL anymore as I copied this to my PC--

"Li-ion batteries should be stored charged. If they're stored for over three months with a cell voltage of less than 2.5V, unrecoverable capacity loss will occur. Also, leakage and corrosion are more likely. Some Li-ion battery packs won't allow a recharge if individual cell voltages fall below 2.5V, because at this point cells will have chemically altered and recharging could be hazardous. It's best to store Li-ion batteries charged at between 70 and 90 per cent of full capacity."
