I have three flat top VTC4s. I went to change one out a little while ago, and noticed that there was a dent in the flat top, over 5mm deep I would say. I'd guess it's from when it got knocked off the table due to my own carelessness. It was vaping fine after the incident, but now I'm quite nervous about charging or using this battery what with the dented flat top.
Should I even attempt to repair it or just retire it?
