Are sealed lead-acid batteries safe to use indoors?
I have a small, 12V sealed lead-acid battery. I know regular lead-acid batteries can be dangerous to use or charge indoors, due to the fumes they release and the potential for acid to leak out or spill. A sealed lead-acid battery wont release fumes or spill though, correct? Does this make it safe to use/charge indoors? Thank you!
