So somehow I managed to knock off the little plastic button on the battery. and lost it somewhere in my less than tidy car. If I use a paperclip, I can still push down, but that is pretty mickeymouse. Any ideas? anyone have a dead 510 battery they could send me? Any vendor ideas (ie who could send me a replacement button) I know this is ridiculous, but I only have three batteries, and even the extended ones don't last long.
