Battery odour, Headaches and polish smell ... Why?
I repair a lot of iPhones , ipads, but sometimes when i have to change a battery there's a sort of smell like polish remover coming from the battery .
The odour is not very annoying but when i sniff/breathe this odour, I feel a few headaches during 1 hour or less.
This odour can also be breathed sometimes on new batteries (Which are defective) or used batteries and sometimes also when taking off the batteries when it is broken
What this smell is composed of ?
Is this a good question?
