A typical CR2032 can source much more current than 5 mA. You could pull 100mA from it, for under an hour, with some caveats about it''s high ESR. The nominal current is to establish a base lifetime of the battery. CR2032, and coin cells in general, are meant for low current, long life applications, like real time clocks or battery backups of data.
In simpler terms, a battery current sensor is a tool that tells you how much electrical current is flowing through a circuit or a battery at a given time.

Assuming the battery does eventually indicate a full charge, disconnect it from the charger and let it sit for at least several hours, but ideally overnight. That''s because the first test is to check the static, or resting voltage of the battery, and for the results to be accurate it''s important that the battery hasn''t done any work recently.
Your charger can only discharge at a maximum of 1 Amp, which for a 3200mAh battery is 1A/3.2Ah = 0.3C. To discharge at 1C you need to draw 3.2A. Theoretically to get a 1C discharge you need a 3.2A constant current sink, but a …

As a rule of thumb small li-ion or li-poly batteries can be charged and discharged at around 1C. "C" is a unit of measure for current equal to the cell capacity divided by one hour; so for a 200mAh battery, 1C is 200mA. Example: common 402025 150mAh battery from Adafruit: quick charge 1C, maximum continuous discharge 1C.. Slower charge and discharge eg 0.5C or …

maximum capacity. A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would be 50 Amps. Similarly, an E-rate describes the discharge power.
They are "apples" but not exactly the same apple. You''ve got to go beyond just the eye test. Lithium Ion battery testing involves even more variable that include application use. Since most people are more familiar with lead acid batteries, let''s apply the two tests above to a lithium battery, the Safari UT. The Safari UT works with 12V systems.
Testing a Lithium-Ion Battery: Set the multimeter to measure DC voltage. Connect the multimeter probes to the positive and negative terminals of the lithium-ion battery. Check the voltage reading.
