It’s not just fire but explosion as well with bad battery packs. Some years ago some friend bought a “comparable” laptop battery off eBay for an older laptop. They were charging it one day and battery exploded. Fortunately they were not sitting in front of it. I was in the office when my friend got the call from his wife and asked me to come look at the computer. We arrived with smoke in the room and little fires burning in different corners of the room with a scorch mark on the desk and the laptop in the middle of the floor with smoke wafting out of it. I dug some charred plastic out of the battery compartment and hooked it up to external power and it booted ok. Be safe out there kids.
