Have you tried a solargizer for a week and then charge a day ,
Worked for my dead battery unused for 6 months.
Now I leave it on a the solargizer

EDTA

I was trying to revive two deep cycle marine batteries. Perhaps I need to
try it again. I have a pallet full of old batteries waiting for the
recyclers. So I have plenty of materials to play with! Perhaps a
combination of shocking the batteries with the higher voltage and the use of
EDTA can bring a few of them back from the dead.
Thanks,
Dave
