The Arduino is removed from this example for simplification.
From what information i could find to determine the theoretical battery life of a given device/circuit you divide the battery capacitance in mA-h by the current drawn by said device/circuit, and some even recommend multiplying that by 0.7 I’m guessing for a more real life estimate.
So my questions are:
(A) is this a good method
(B) is there any additional, non-minor, information one should take into account.
(C) And this is the important one, if i am running (100) 2mA LEDs off (1) 9v
595 mA-h should i expect in the neighborhood of 2.08 to 2.97 hours of
lifetime in average temp. conditions?
Thank you for your time
EDIT: revised the calculated hours… originally was for 1 not 100 2mA LEDs.
