failure is not uncommonfor any battery brand, and some cells may deteriorate at a faster rate than others. To identify abnormal cell(s) in a string, bar graphs for cell voltage and IR (Internal Resistance) are crucial. There are different methods to test IR, but not all
Internal resistance of a DC battery doesn''t require nearly so much ceremony; it''s the voltage change from open when you apply a known current, divided by that current. The Prius battery ECU computes it automatically for every pair of modules in the battery and can report the numbers to you over the diagnostic port.
When the battery''s internal resistance, R DC, is 1 Ω, and the load, R, is 9 Ω, the battery outputs a voltage of 9 V. However, if the internal resistance increases to 2 Ω, the output voltage drops to approximately 8.2 V.
