Detecting the status of a Victron LFP BMS battery (no smart)

Hello,

I would like to buy a used LPF battery. The owner says he bought it at the age of 1.5 years. Now it stood in his basement for over 1 year without any cables connected. No loading and no unloading. The measured voltage is 13.1 volts.

What is the chance, that the battery will still have its full capacity? Can there be problems?

I think I have no way to check it locally, because it is 600km away.

It is still a battery without "smart". Is it correct that at that time the cells of Winston (LiFeYPo) were installed? Does anyone know the date on which Victron switched from NO-SMART to SMART?

Or can I get the real age by asking Viltron with the serial-number?

Many Thanks

I don't know the answer, but it will probably help to state the exact type (voltage / capacity / ??)
