Background: Removed replacement battery from its bag. At first, the battery smelled sort-of-grassy/toxic-chemically. When installing it, the battery smelled more like new plastic/rubber or something. A few hours later, I can’t detect either smell from the installed battery, even when close up. The inside of the (closed) battery bag still smells like sort-of-grass/toxic-chemicals. Problem: Is this safe/normal? The battery doesn’t seem to smell now, but the bag’s inside still does. I don’t think that either smell was sweet/acetone-like.
You should be safe. By the sounds of it that odor was coming from the bag, not the battery. If you get a rubbing alcohol or burnt skittles like odor that’s when you should start to worry.
