If someone is trying to get away from something with addictive characteristics, the last thing they need is somebody coming by to make that harder. The presumption that I don't know anything about batteries is bad enough. Disregarding what I'm up to is worse. It's like somebody talking about how they're quitting drinking and popping up to say, "But studies show health benefits to drinking!" While true, it's well known and incredibly unhelpful.

And as the replies show, his unhelpful intervention could well be wrong to boot.
