[RE-wrenches] Fully discharged AGM battery

[Peter Parrish]

I have a client who fully discharged a pair of SunXtender PVX3050T 6V
batteries. They were about one year old. They had no load voltages of 1.77
and 0.87 V respectively. I have ordered him a new pair but I wondered if
they could be resuscitated to some degree and be used for some odd purpose
around the shop.
 
I tried to charge them using a Vector VEC1095A charger on the AGM setting:
they took about 7.5 A at 14.4 V for about 5 minutes and then shut down. I am
now desulphating them, which I think takes the better part of a day. And I
then plan to run them through another charge cycle
 
Is there any thing else that I can do to get them in some sort of
serviceable shape?
