Thanks Robin,
 They are 12V, so yes I am very worried, never seen 12V batteries that low
and recovered. Trying to fix/reverse engineer my own broken desulfator
(sigh) and charge at 500mA with my fingers well crossed. I just hoped that
someone would have a super smart charger that may be more effective.
 But yes, seeing as I likely have 140kg of scrap I was hoping a new battery
would turn up 8)

Are they 6 or 12v batteries? If 12v then a trip to the scrap yard is in
order - very unlikely to be of any use. If 6v then a slow charge would be
better than a fast one. If they are flooded batteries, check the SG and
level to see if the values agree with the volts. Battery University is
