The most accurate way to measure battery capacity is through a discharge test. In this process, the battery is discharged at a known rate (in amps) until it reaches a predefined voltage limit. By multiplying the discharge rate by the time it takes for the battery to reach that limit, you can calculate the battery''s capacity in amp-hours (Ah).
The conventional test to obtain the direct current internal resistance (DCIR) has only experimented with a duration time of 5 seconds in the discharge region~.
