Looking for experiences of swollen battery replacement, fire

My Dell battery is swollen, but not hot. I’ve searched and found the “What to do with a swollen battery.” I’ve run the battery down and it’s not connected to power. I have it on a nonflammable surface and would like to try to remove and replace it myself (especially given the present world situation). I’m looking for advice, especially from people who’ve had experience, with unscrewing the T5 screws, the un/likelihood of fire if I don’t puncture, etc. I’m studying up on safety, etc. but just am looking for helpful tips, do’s/don’t’s. Thank you!
