I purchased two batteries (auto titan diamonds) and am having constant issues with one of them. Doesn't consistently work when I take a hit, and the draw seems way harder than the other one. I have tried that trick with raising the center thing at the top with a pin several times now. Seems to make it better for a short while, but then it goes right back to being unruly. Any other ideas on how to fix it, or is it a dud battery? Tired of messing with it. Thanks!
