Have found that measuring the impedance of cells in batteries will give you a good indication of each individual cell condition and shape , a HP 4328A is the standart that most batteries manufacture use ( the newer HP4338B cost over $ 5,000) the older model is very good and available on e-bay from 100 to several hundreds .
The lower the impedance , more effecient the charging and discharging becomes .
Variation in cell figurs should not be over 60% , the actual figure will varied in relation to size (a/H) chemistries ,age , state of charge , temperature .
Impedance is usualy the first reading , that I concentrate on .
Would appreciate any comments regarding this note .
