Could it be a setting on the gun that the kid screwed up? Is there a way to do a factory rest?
What's happening is that the solenoid is not kicking the sear hard enough to make it release the bolt reliably.
This is most often caused by a low or cheap battery, but it seems you've already tried that.
Make sure the battery connection is good and that the battery is not jostling below the contact prongs. Rather than bending the prongs, which can cause them to break, you might want to try wedging some paper beneath the battery to give it a secure fit.
After that, you may want to try raising the gun's dwell setting. Normal SLGs don't have this software feature but the UL does. Consult your manual and give this a try. Dwell is the only software setting that can affect the gun's ability to fire.
Finally, as a last resort you may need to try compressing the sear spring. Remove the grip frame and push out the sear pin to remove the sear and gain access to its spring. Pinch it down with your fingers to reduce its strength slightly, but beware: if you reduce the spring strength too much the sear may not be able to hold onto the bolt and the gun will go into uncontrollable full auto. There's a balance to be achieved here. If you think you've compressed it too much, remove it and stretch it slightly. Again, try this last.
Hope this helps.

You're probably going to have to solder on a snap-on battery connection then.
