Title: One Star because Zero is not an option
Review: The description says that it is compatible with the V400. It is not. The other side of the battery says its for the V300.It powered the phone but I could not call out and all in coming calls go to voice mail. As soon as I put the old (OE) battery back in, I was able place and receive calls immediately.
