The battery was delivered in less than 2 days. However it does not present a good appearance at the connector. Following the tutorials found on the net I could install the replacement battery without concern. After reassembly, charging, and then, surprise, no charge (the battery remains at 7%) and longer causes a hard reset. Assuming a bad connection, I proceed to disassembly / reassembly without success (no load over 7%). New disassembly and reassembly of the original battery (which was a bit run its course) and then the charge is normally true. So it is a purchase not convincing
