seriously be careful_ eveyone keeps warning me of my mod, and all i have is a sticky fire-button.
if by battery you mean the battery itself, then chuck it. if the board is fried, and by battery you mean the mod, that's equally dangerous and no change of battry cells is going to save it.
you sure you haven't seriously burnt the cotton or fried the coils? how's the vape?
someone in this thread explained mentioned different types of smoke detectors have different reactions to vapes
indoor vaping, mould, condensation, etc.
i'm just guessing that even an alarm that isn't set off by normal vape might react to the smoke content of the vape caused by the burnt wick, maybe by the vapour going thru fried coils as well
