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 bring it home. Would it be bad to do the following?

Charge overnight on 14.4v, 10amp smart charger. Then condition with meanwell another day.

???

Seems a new starting battery would be a better choice. I wouldn’t want to get stuck somewhere.

PS

Twiddle the voltage setting on the Meanwell to 14.4 volts and you can leave it humming away for 2 weeks -- no sweat. Winter temperatures compensated for advice.

When I was using the meanwell on the first of the fiamms, I set it at 14.7 but it went up to 15.2 before I realised.

Is that not a concern at 14.4? Is the meanwell preferred over the smart charger for overnight at 14.4?

What exactly is dead....the charger OR the battery ??

If it is the battery, it probably is a total loss.

Under those conditions, worrying about "conditioning" is probably a total waste of time.

To try and RECOVER the battery, put it on the highest capacity charger that you have for about 4 hours. If that charger is fully automatic, leave it connected for 12 hours or more to see if it comes back up to voltage or not (12.8 at least). But that's probably a waste of time too.

Desulfating, I think. Mex is the battery pro [emoticon]
