battery selection

I'm at a tow lot they're are 5 6 gen2 all have batties in them I think but not connected. Guy says if they here they dead . You can have 1..... Two im looking at show 220.9V the other 211.8V . Which one to take?

 

Open case tops one top looks brand new the other much older but clean . The 220V unit showing darken bus bars lite frosting on nuts . The 211V unit lift cover looks brand new inside every sticker on every module is perfectly legible All the bus bars are copper there's no frosting One of the bus bars in the middle looks like it was brand new really weird doesn't look like the battery's ever been opened up or messed with other than the fact that the little orange thing is missing that you have to remove with the safety switch there is no blue corrosion on any of the high tension wires and their lugs the inside of the black labeled battery computer is as clean as I've ever seen in my life there's not any corrosion on any of the lugs from the pins to the board close it back up put it back in the unit test it again it's showing 211.8 volts so I took this one because of how clean it is.
