Since MAX34407 measures the common-mode load voltage from the lower voltage terminal of the sense resistor, this value is included in the input power measurement rather than in the output power measurement. You can compensate measured output power by adding the calculated sense resistor power dissipation, which yields the total output power. …
To measure battery capacity, you need to fully charge the battery first. Then, you disconnect it from any charging source and connect it to the multimeter or battery analyzer. The device will record the voltage and current as you discharge the battery. By integrating the current over time, you can determine the battery''s capacity.
My answer would be: get a shunt-type reference for a voltage that is lower than the battery range of interest. Let''s assume a ~5V battery, and a TL431 or the like as 2.5V reference. Now measure the TL431 voltage, using the battery as reference. Assume a 10-bit A/D (most common), that reads N. Now you know that . N * (Battery / 1023) = 2.5 hence
