@fabriziocornali - To clarify things a bit. The battery is made up of two assemblies the batteries them selves and the controller board which holds the micro controller which interfaces with the battery assembly both power and sensors. CoconutBattery is reading the dialog from the controller (date). So… Its possible the controller board was sitting on the shelf for awhile, while the battery assy was newer. COVID has messed up a lot of stuff, so its possible the battery maker was trying to use what they had (granted way old). But, that doesn’t help you, iFixit clearly is making this right which is what I would expect. Once you put the battery in check the date and let us know what you end up getting and if you still have issues.
