Has anyone tried to charge long dead lead acid batteries?  I
have a batch of Gates 6v 2.5 amp hour sealed batteries made 
up of 3 "D" sized cells.  These are surplus batteries that 
have probably been discharged for years.  When I try to
 charge them, no appreciable current flows, even at 12v DC 
input with no current limiting resistor.  Not having done 
much with lead acid batteries, am I doing something wrong, or 
are they beyond hope?  Any help would be appreciated.
