Another AGM conditioning question
This is my chassis battery, an agm I got used and have little experience with. Trickle charger failed in storage, it is dead as a doornail. Not covenient to babysit it for long hours on meanwell or...

Do you have another healthy enough battery you can hook the questionable AGM to, in parallel?
The MEgawatt will self limit to its maximum amperage. My meanwell on a ~60AH calcium calcium maintenance free starting battery drained to 10v had to be turned down to its lowest setting to keep amperage below 20, as moreamperage than this the battery temperature rose quickly. My meanwell is capable of 40 amps.
A battery drained as low as the OP's I would likely not even bother with, unless I paralleled another 12v battery to it and then put then put the charging source on the other battery.
I'd still not have much hope. While most flooded deep cycle say 0% charged is 10.5v, I see 'some' AGM's saying voltages in the mid 11's equal 100% dischrged:
Crown1 AGM pdf saying 11.64 is 100% discharged
If the battery was slowly brough to 1.7v i doubt I would waste any time effort or electricity trying to get it to rest above 12v ever again. Even if it did, a small load would likely have it back below 10.5v again as its capacity is likely long gone.
but best of luck and keep flammables away from it
