There has been a batch of LG HG2s that has turned out to be either defective or possibly counterfeit.
Here is a few links that have details:

Mooch suggests, and I agree that the 30Q would probably be a smarter purchase until they get this straightened out. I have noticed a big "LG Blowout" from some vendors, and I suspect it is to clear their inventory of any of these batteries, if they actually have any of the Low Grade/Counterfeit batteries.
