Yes the quest silo launchers are a 9volt killer, We did a test on 9Volts early this spring. If you are going to continue to use 9volt batteries, we have proven the new eveready energizer silver lable out lasted the duracell by about 3 times. a fresh, duracell got 5 to 7 launches, the New Energizer burned 17 igniters before failure.
If you want a quick and easy way to remedy this problem without rewiring the system. a simple drop line of 24/2gage lamp cord with a couple alligator clips and the top from one of your spent 9 volt batteries will allow the system to be used with any 12volt system without damage... I've used this add on or over a year without any damage to the launcher or contorller.
You will have to disassemble the dead 9 volt battery with 2 pair of needle nosed pliers. I found it easiest to work one corner of the seam loose, than hold the outer alum skin with one pair and twist/roll the skin onto the other. cut the lead strips leaving enought to be soldered to about 5' of 2 conductor 24ga. lamp cord from radio shack. after soldering, wrap the edge of the 9volt head with 1/2" making tape making a pocket. pour epoxy into the pocket and allow to set. strip of the tape. Now add the alligator clips. attach the contoller 9volt cap to your new cord. I filed a small opening in the edge of the battery door cover to pass the lampcord, stow the connected cord and cap in the battery compartment and close the cover.. connect to any 12volt battery you like. Works wonderfully

Hope this helps
