I must say that is the one part of the MRT design where I do the "V-8 salute" and say "what were they thinking?" The screws should have been captive.
All I did (to avoid that very problem) was take the screws with to the hardware store and find a "shakeproof" (i think thats what they call them, http://ecx.images-amazon.com/images/I/31diHDKqLcL.jpg) washer that i could force over it on the inside of the battery cover so when I spin them loose (i have to go back and forth so it doesn't bend to far) they still can't pop out. It took a while to find one with a small enough OD to not be near to the battery terminals though.
