Most of those type of units have really poor voltage regulation, open
circuit voltage on the 'Start' setting may be as high as 24v or more!
My guess is the high voltage (possibly in the form of a huge inrush current
when the solenoid contacts close) is what killed the solenoid.
You can still use the charger, just leave the battery in the circuit.
Probably best to turn the charger down, and then give the starter a rest
when the battery gets tired; as the starter will also have a very limited
duty cycle.
