    I have a portable scanner that is rechargable(7.2V/600mAh) and every time I get it out of the drawer, it has self-discharged. That's not much help if it's storming and the power is off. I would like to convert it to run on non-rechargable lithium batteries. As near as I can tell, there aren't any single cell 7.2V lithium batteries made that will fit in the space vacated by the old batteries. I really don't want to have to connect multiple cells together every time I have to replace them. Can I run it on a 9V battery without damaging it? The scanner is also capable of running on 12V DC from a car power point. Does that mean it can handle 12V but 7.2 is enough to power it? Would there be a way to regulate the 9V down to 7.2?
