Query: Looked good at first, then totally died (see comment)

Just purchased this battery a few weeks ago, and it appears to be identical to the stock battery, with the same markings. It is lasting as long as the stock battery did when it was new, so only time will tell how long it can hold its charge. The original battery started losing its charge slowly after about 1 year, and at 2 years, it only gave about 15 minutes of talk time. If this one can at least duplicate that, we'll be happy to have only spent a fraction of the price that Verizon stores charge for this battery.
