When the system is repeatedly discharged to exactly the same point by a microcontroller, then recharged from that exact point, you get a blip in the discharge right there which makes the controller think the battery is _dead_ low if it gets to that point. If you use it to varying levels, no such blip develops, and even if one did, (as long as no precise voltage monitoring controller is involved), you'll probably ride right through the blip. The battery doesn't stop working, it just develops a slight change that persuades some control circuits it has discharged. It still provides current, and the voltage doesn't change enough for most devices to care.
And, to top it all off, even if you are in a memory-prone application, you don't have to discharge to 0 every time. Discharging one in tens of cycles will suffice. Deep discharge cycles are hard on cells, and especially on batteries (reversing risk), so don't wear your cells out prematurely.]]>Oct 24th 2007 3:50PMhttp://www.engadget.com/2007/10/24/chinas-starsway-touts-potassium-battery-powered-pmp/http://www.engadget.com/2007/10/24/chinas-starsway-touts-potassium-battery-powered-pmp/Heh, we once blew a hole into the ceiling during our science class with this.
So for the sake of safety, let it be potassium hydroxide...
