EDIT: I purchased this from CCM Accessories. But the time stamp question is probably a good one for all retailers.Purchased the first of these on 11/12/10 for a trusty v325i. I was chagrined to find the time stamp said 12/07, so the battery was nearly three years old, and unlikely to fully charge. I called them about this and was convinced to try a "3 cycle" charge of 8 hour increments. The battery never had more than 70 minutes talk time, so I asked to swap...was told they had a newer lot in, from 2009. Did the exchange, and the next battery had a time stamp of 12/07.At least their returns department is prompt.If you want to call before ordering and find the age of the lot, that's your best bet. Otherwise forget it.
