[TechAssist] Any way to revitalize dead sealed lead acid batteries?

I found a box of 10 brand new sealed lead acid batteries, 12V 4AH that I 
forgot I had. Problem is, they are all very low or dead. I tried 
connecting my power supply with current limiting but the batteries 
aren't drawing any current at all.

Is there any way to kick these into charging up, or are they garbage?
