(Silicon Chip Magazine March '04) Say you want a 9V battery to supply 40mA to a circuit. That's a pretty modest current but if you use a PP3 style 9V battery it won't last long at all. In fact, if you're using a typical “heavy duty" 9V battery, it will last less than 20 minutes before the voltage drops to 7.8V. That may be enough to stop your circuit working. Or maybe you are using an alkaline type. Depending on the brand and price, you might get about two hours life. Not good.

By comparison, two AA alkaline cells driving this DC-DC Converter circuit to give 9V at 40mA will last about 7 hours. And rechargeable AA cells can be even offer better performance.
