I found a hack where the guy put a super small piece of cork behind the metal "prongs" inside of the housing to push them out towards the battery. Now the batteries sit more snug and are in constant contact and I haven't had a drop out since!
I've been using a bit of folded aluminum foil between the back side of the battery holder (which moves the current from battery to pedal) and the inside of the battery compartment door. This has worked w/o issue, so far.
I figured I could most easily acheive the optimal spacing for this shim using layers of folded foil.
Do any EE's here think using foil is better/worse than using a non-conductive shim hack, like cork?
