Hands up the people that own lead crystal batters and have a charger that delivers the specified volts and currents and program to suit LC batteries.....not one that "will do the job" like Redarc states.
My bet is none of you have.
Thanks Ed the battery on convrete was just a old hand me down bit of advice from the 90's
Crunchy i bought a AGM battery for a dirt bike i owned it came fully charged i lost interest in the bike it sat in my shed for 9 or 11 months from memory i wheeled it out and she fired right up could not believe it, if that was a regular battery it would have been flat after 2 months

Out of interest I'd hook it up in parallel with another fully charged battery using heavy leads then make a run for it, give it half an hour then try it again with your battery charger.Might try a high amp charger to kick it in the guts and see if it can be recovered, tried recovery mode on my 7amp c-tek but its not up to the task - just a pesky red error light the next day.
If you get a result you may be able to revive it then by giving it a few full charge/discharge cycles.
It's ability to charge, hold a charge & load testing would tell the story.
Have you measured the open circuit Voltage at it's battery terminals?
