I just got a new battery from ifixit and it smells like nail varnish. Is this bad?
It’ll be the adhesive holding the wrapper on. Do you usually sniff batteries? 😂
I doubt it. I have had batteries smell like all sorts of things. For point of reference, a leaking lithium ion battery typically has a vaguely sweet or fruity smell. If you’re concerned, give the battery a good physical inspection before installing it (wear some latex or nitrile gloves for protection). If it is leaking, you will likely see some sort of damage to the battery. Pay attention to corners in particular.
