Query: ONE SIZE DOESN'T FIT ALL

As far as quality is concerned,this is is really not much different than the other replacement batteries from AT&T.That; seems to be more related to which country or company was the supplier.Electrically they are all comparable,but,it is the physical size that separates one from another.Seems more like a way to sell different types of batteries.Some have connectors and other don't.It is like shoes one size fits the others don't.Always wondered why this item,after a short while was not readily available even from Bestbuy where the phone was purchased.For some reason it was restricted to one AT&T; and Vtech model only so there wasn't much demand for this item.If the shoe store only carries small shoes because they sell better,it won't work if you take a medium shoe.Not much choice here.
