Bulging Stick up cam 1st gen

Hi. I have 3 2+ year old 1st gen stick up cams and 2 of them are bulging but all of them still works perfectly fine. Wondering if it is safe to continue using them? Sharing pictures of 2 of them. Thanks for the help.

I wouldn’t charge it. The battery has failed. If you charge it, there is a good chance it may catch fire…

More information on it here.

Don’t throw it in the garbage…
