Not sure if it's a Sanyo problem or a Zebralight problem, but I bought a SC64c to EDC and discovered to my dismay that if it even so much as falls off a coffee table it will smash the top of the NCR18650GA that Zebralight sells with it. Before today I had always assumed that flat-top batteries were solid under the flat top, but now I know they cave in.
