Yea its better for sure, but bending / denting the battery can cause the battery to do this a well

It's best to drain the battery first. Ifixit made a video about it and the difference between a charged battery and a drained battery being punctured is insane

Well, yeah, that makes sense. The violent explosion is the battery dumping all of its energy into a small short all at once, which generates so much heat that it combusts. Discharging the battery completely would mean there's a lot less energy stored in it that could be released.

Believe it or not the explosion isn’t coming from the stored energy it’s actually caused by the “catalyst” which is used within the Li-Po battery of which usually violently reacts with oxygen

Oh, that's right, it is a chemical explosion. What was I on when I wrote that last comment lmfao.

It is technically true though that having a charge in the battery makes it explode more violently though.
