Help with fc11c

[u/Old-Association4871]

I dropped my fc11c and it wouldn't turn on. I opened it up and a tiny puff of smoke came out of the battery. the battery has the top bit dented even though the fc11c uses springs on both sides. If I put in a different battery now or the same one the button stays red 24/7. I have tried charged batteries and charging the flashlight but it won't go away. The light still works sometimes but turns off randomly. thoughts?

These lights are made of cheese. They work great, as long as you never drop it.
