Save flat batteries

I've been given two Victron 100ah Lithium Smart Batteries. I can't connect to them by Bluetooth & they are both showing less than 4 volts across the terminals. I'm guessing that they are beyond any hope. Does anyone have any ideas if it would be possible to bring them back to life?

Find the lithium smart battery manual and there is a section in there with a recovery procedure. However, at 4V the cells will have likely suffered major damage and extreme caution is required if trying to reactivate them.
