Had problem with batteries since purchase, extremely short life or "change batteries" immediately with new batteries. Bought one brand of ultimate lithium that worked the best, but still too short. Per advice here, I have bent contact up. But then I put a small piece of foam under the contact to maintain the change. Hopefully this will keep me from having to go back and re-bend the contact, thus breaking it. I'll let you know...
