Hi guy!This is my first simple tutorial, and I'll show you a simple way to open a 9v battery..
(ciao ragazzi questo e il mio primo semplice tutorial, e vi mostrero un modo semplice per aprire una batteria da 9v..)

Step 1: what you need (occorrente)

the material..(il materiale)
Inside the battery that can pack a 1.5 V be 6 and how do be 6 and how do
Thats a terrible way to open a 9v battery. Why not bend the metal tabs on the bottom out and push the casing off? That way there is no risk of cutting into a battery and spraying chemicals all over the place.
I'm also not sure what one would use the "smaller" batteries for...
they work better for AAA batteries rather than AA
If you were to fold the metal tabs over on the battery, you could substitute them for a AA in a pinch, they wouldn't last as long but they will still work for more information, look up Kipkays instructable on a 9V battery hack. :) happy hacking
you could use the batteries for some low power project in place of a AAA because they are 1.5 V (nominal) each or if you need a battery smaller than a AAA.
Here Here. It looks like the batteries took a bit of abuse in opening the case. A Leatherman or Gerber is all you need to get the bottom off. I would not recommend anyone opening a 9V like this.
this has been done like 6 other times on this site and this is perhaps the worst way to do it cuz if u cut the batteries on the inside and u get it on ur skin your gonna be screwed. SO DONT DO IT THIS WAY!!!
