The Difference Between Battery Resistance & Impedance Testing …
Additionally, impedance is dependent on the frequency used in the test; the measured impedance value of a cell tested at, say, 85Hz will be different to the value obtained when using 115Hz. Different instrument manufacturers favour different frequencies to test for impedance, so none will be the same value for the same cell.
How to measure a battery''s internal resistance with a battery …
Since weld anomalies will prevent the battery pack from delivering its full level of performance, it is recommended to test assembled battery packs using a battery tester. The Hioki BT3562 can measure the internal resistance of battery packs of up to 60 V, while the BT3563 can measure the internal resistance of battery packs of up to 300 V.
