Lastly, the title of the talk can be tempered a bit. No? We all know what a leaking battery mean right? Toxic.

Come on. Python has had the 'batteries' metaphor for decades and this is a straightforward and obvious play on it. You're bringing 'toxic' into this which I suppose is technically and biochemically correct (both, surely, the best kinds of correct) but has far, far more negative connotations than the title warrants. You're having to work really hard to make a generic thing sound dreadful.
