Ok, so I got a new battery for my laptop and I don’t think I’m using it correctly. With all these "Never"s, how am I supposed to get it to work??

-Never throw the battery pack into fire, as that could cause the battery pack to explode.
-Never hammer a nail into the battery pack.
-Never hit a hammer on the battery pack.

I’ve never used a battery before that didn’t involve a hammer and some fire — what gives??
