Battery died while garaged

Depends on the state of charge now. If you have a few hours, I'd put it on 2A. If you are in a hurry, go with 6A. If the battery needs the extra amps, it'll take it; if it still has some charge, the charger/battery should self-regulate (if everything IRL worked like theory). But many chargers designed for charging a battery cannot properly float a battery.

The more I think about it, the more strongly I want to suggest buying a new float charger that is designed to maintain charge during storage. You can find cheap ones for $10 and better-than-adequate ones can be found for $30-50. As others have mentioned, over-charging the battery can kill it. It can generate enough heat to cause a fire (not that likely with a small charger like you have), and can even release enough hydrogen gas to be an explosion hazard (always possible, so make sure the area around the battery is well-ventilated when charging).

Thank you. Sounds like I'll just buy a new charger if they're that inexpensive. I'm in no hurry to charge it, so I'll put it on 2A in the meantime. Should leaving it on this setting overnight do the trick? At least Ill have a new charger for next winter (if I keep the car).

If it's a decent charger, it will float (close enough for overnight) once the battery is charged.

The charger you have may work for storage, but why risk it when the right one is so cheap? But, yeah, the charger you have should work fine for overnight use (unless it's a POS).
