dont like this:::::: > [@web site](#): > > 1. you can save even more, too > Submitted by mind on Mon, 2007/08/20 - 12:02am. > you can save even more money if you do this with a car battery, which is 12 volts also. however, because car batteries contain much more energy, you want to partially discharge it first! the best way to do this is to take a metal bar and put it across the battery terminals for ten minutes or so. then use the claw part of a hammer to crack it open so you can remove the individual cells. make sure you do all of this outside, as it will be a bit messy. ---

Cool, but who owns a bunch of stuff that uses button cells? My laser pointer, but it’s not like I use that enough to need to replace the batteries. The 9volt looks more promising since it looks like those are AAA sized cells. ---
