Yeah, I've tried a small steel washer on the positive contact but the issue still happens, which makes me feel that it's internal to these Meta batteries or something else. It might be the small pogo spring contacts under the battery.

Meta - your reply is useless and disrespectful. If you don’t have a real solution (or are a bot) stop belittling us with irrelevant responses
Could this be the problem? Also, similar problem here.
Thanks Fish… you are on the right track …. i had found that article, but the solution that worked for me was to put a folded up piece of paper in the battery compartment between the cover and the battery. Seems to be working so far. Pretty poor product design IMO; especially for a device that will encounter a lot of movement… Meta should include a small rubber pad to adhere to the battery cover. I have some here and will do that as a permanent fix if these keep working.
