The same thing mine did, charge the battery. My first power supply was one of those puny supplies and a car battery, it worked.

At three amps, I'd worry a bit about it overcharging the battery if left on for long periods of time. If you're only going to turn it on while you're using it, though, you should be okay.
All the world’s a stage, but obviously the play is unrehearsed and everybody is ad-libbing his lines. Maybe that’s why it’s hard to tell if we’re living in a tragedy or a farce.
Do it, but add a charging regulator between the battery and supply.

If nothing else, this one is a good read and can get some thought juices flowing.

It could just charge the battery, fry the battery or fry the PSU.
It depends on the size and type of battery. If it is a deeply discharged AGM battery for example it will fry the power supply for sure (or trip its overcurrent mechanism, or blow the fuse).
I am surprised at such a sudden deterioration in a woman whose only ailment was a lazy anus.
Good find. That will work nicely with a 120w panel which makes it perfect for field day.
