deep battery discharge [RE-wrenches]

[Ron Young]

<x-flowed>

Hi all,
I've got a client who inadvertently discharged his relatively new set 
of 1900 a/h lead acid batteries (left a light on that was directly 
wired for about three weeks). The voltage reading is 10.5v, I can't 
even get a reading on a hydrometer so it looks like the electrolyte is 
pretty much water. The 750 watt 12v array is only registering .4 amp in 
bright sun -through an SB50L -is this because the batteries can't 
accept a charge now? Are they toast or can they be recovered?
