I never knew this, cool.


wow,this is cool..

yeah this is definitely cool.

I opened a 9-volt battery before and had one of those cells explode on me, I'm not sure what exactly caused it, I think I might have caused a short with the pliers some how but that's just my guess. I didn't get hurt (it exploded in my hand) and it didn't damage my clothes or the environment but it was extremely loud and it left black dust on me.

Thing is ? 3 aaa batterys are cheaper than one 9 volt.About half the price.

aaa batteries are 1,5 volt so you need 6 of them to get 9 volt, that would be the same price as one 9-volt battery

how do you get free internet on your mobile phone. please send the setting to the following email add

Even if aaa's are cheaper, if you need them quickly and all you have on hand is 9volt, then this is worthwhile.
