Input voltage V — try 4.80 fresh, 3.50 flat

Output voltage V

Load while awake mA

Quiescent current mA — 5 µA is 0.005

Pack capacity mAh

Awake window s

Wake interval s

A buck's quiescent mA, for the comparison

Enter your voltages and load, then press Calculate.

From the book — Chapter 10. heat = (V_in − V_out) × I. Efficiency = V_out ÷ V_in and nothing else — so it is worst when the cells are newest.
