I have a Duracell D battery that has a voltage of 1.5V. I am curious on how much current I can expect to draw from this batter. Wikipedia shows that for a standard D cell alkaline battery the capacity is
20500 (mAh). Does this mean that each battery should be able to provide 20 A h?My system draws about 1A so it should run for 20 hours? Unfortunately the battery doesn't seem to be giving me back that much current and I was hoping if someone could explain what is going on. In fact when I first power up my system there is a surger of current drawn and the D cells don't seem to handle that well.
How can I figure how much current the D cell battery is rated to provided? I don't see anything on the packaging.
If I need more current with the same batteries what should I do? Line them up in parallel? Will this double the current?
Thanks for your thoughts.
